Description of the Invention (1) This invention is an application for a manufacturing method of cement infiltrating materials and cement compositions, and concrete products made using it. The invention of heating and curing methods such as steam curing to make mortar or cement promote its coagulation and improve strength in a short period of time is often used when the cement secondary product is lifted and peeled off. Until now, secondary cement products often have many varieties, types, and are sold in large quantities. Correspondingly, the secondary product workshop must always have many types of mold frames, and it must have a large place for placing products. On the field. Therefore, early demolding methods such as how to improve production efficiency with fewer mold frames are often the subject of research. Generally, the method of early stripping is to increase the curing temperature, use high hydraulic cement, or use strong hardening accelerators such as chloride or nitrate and dithiocyanate to promote cement hardening. However, although the water and reaction of such an unreasonable improvement of cement can obtain the peeling strength in a short period of time (different depending on the shape and weight of the secondary product, roughly speaking, the peeling strength of large and heavy articles is 8 N / mm2 ~ 15N / mm2), but the strength will be reduced afterwards, so in order to ensure the strength of the design, the amount of cement per unit must be increased again, and new problems arise. The present inventors have proposed improvements to the disadvantages of the above-mentioned conventional coagulation promotion methods, that is, the use of ettringite containing gypsum and alumina sulfate or alum stone with ya, acid ya, and biquat sulphate Method for adding stone materials (Japanese Patent Application Laid-Open No. 4-160042). Although this method can prevent the peeling strength obtained by heating and curing for a short time, the Chinese national standard (CNS) A4 specification (210X297 mm) is applied to this paper size (read the precautions on the back of the first cabinet and then fill out this page). Order, —4 — Printed by the Consumer Standards Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs A7 B7 V. Description of the invention (2) Long-term reduction, but sulphite and other products were suppressed by sharp anti-eagles such as aluminum sulfate, which accelerated the process. For purposes such as manufacturing cycles, the pre-aging time before heating and aging is shorter, and because the heating rate is too fast, cracking due to thermal expansion cannot be effectively suppressed, so there are still problems. The inventors have conducted intensive research results in order to solve the above problems, and found that in addition to ensuring operation time, it can also reasonably promote coagulation, shorten the premature aging time, and accelerate the maturation time without generating excellent thermal expansion. Film method, thus completing the present invention. That is, the present invention is (1) a cement cementitious material containing gypsum and aluminum sulfate and / or alum stone and activated silica. (2) In addition, it may further contain one or two or more kinds of alkali metal aluminate or alkali metal silicate (Γ) cement cement material. (3) Cement infiltrates contained in (1) or (2) containing one or two or more hardening substances and potentially hydraulic substances. (4) A cement composition containing cement and any of (1) to (3), the cement admixture contained therein. (5) A method for manufacturing a concrete product, which uses the cement admixture contained in any one of (1) to (3), kneads it with mortar or concrete, and after molding with a mold frame, the temperature ranges from 40 to 100 °. C heat and mature. The present invention will be described in detail below. The gypsum used in the present invention may be generally called insoluble or insoluble type I I anhydrous gypsum or dihydrate gypsum, hemihydrate gypsum, and soluble type I I I anhydrous gypsum, all of which have long-term strength effects. The added amount is 100 parts by weight to the cement, which is converted to Ca S 04 at most 6 parts by weight, more preferably 5 parts by weight or less, and the optimal range is 0.2 to 4 parts by weight.

Description of the Invention (3) Although it does not reach 0.2 parts by weight, it only slightly changes the long-term strength. When it exceeds 6 parts by weight, its long-term strength is still good, but the setting time increases. The effect of shortening the pre-aging time or the effect of suppressing cracking caused by thermal expansion is not good, so it is not a good choice. In addition, among gypsum, it is best to use type II anhydrous gypsum called insoluble or hardly soluble. The surface area of the Bryan powder surface measurement method is not particularly limited, but it is 2 50 0 cm 2 / More than g is preferred. In addition, the aluminum sulfate and alum stone of the present invention are generally commercially available articles. Although they have a coagulation promoting effect and a short interhumidity strength after heating and ripening, they have a small effect on suppressing cracking after thermal expansion. Therefore, substances containing crystal water or substances that can be converted into anhydrous salts after calcination can be used. Regardless of each of these substances, when used alone or in combination at any ratio, each of them is converted to the total amount of anhydrous substances, so that at most 2.5 parts by weight of cement is added to 2.5 parts by weight. ' , More preferably 2.0 parts by weight or less, and the optimal range is 0.1 to 1.5 parts by weight. If it is less than 0.1 part by weight, the shortening effect of the scouring time or short-term strength is small. When it exceeds 2.5 parts by weight, the workability required for molding cannot be ensured, and it is easy to coagulate rapidly, which is disadvantageous for use. In addition, because of its high reactivity, there is no particular limitation on the degree of powder or particle size. Commercially available granular or fine powder can be used directly, or it can be used after being crushed. The active silica used in the present invention may be, for example, silica powder, dusty sand dioxide powder, metakaolin, ashes or floatation of sanded wood, and the like. Therefore, when these ultra-fine powders, which are finer than cement, are used in combination with gypsum or aluminum sulfate and / or alum stone, as long as they are very small, they have the ability to promote the setting of paper.

The above 'the cement cementitious material containing gypsum and aluminum sulfate and / or alum stone and active silica is preferable to 8.5 parts by weight to 100 parts by weight of cement', preferably 8.5 parts by weight Hereinafter, the best is 0.35 ~ 6.5 parts by weight. i. The present invention is a combination of gypsum and aluminum sulfate and / or alum stone with active silicon dioxide. Under the premise of promoting the setting effect, shortening the pre-maturation time and suppressing the cracking phenomenon of thermal expansion, Alkali metal aluminate or alkali metal silicon salt can be used together. Among them, alkali metals are sodium, potassium, lithium, and the like. These compounding amounts are preferably 100 parts by weight of the cement, preferably 1.0 part by weight or less, more preferably 0.8 parts by weight or less, and most preferably 0.04 to 0.6 parts by weight. When it is less than 0.04 parts by weight, the effect of accelerating the setting is poor. When it exceeds 1.0 part by weight, the cement often undergoes rapid setting due to the difference in the amount or type of cement, so it is not a good choice. Above, the cement cementitious material containing gypsum and aluminum sulfate and / or alum stone and active silica and alkali metal aluminate or alkali metal silicate is 1 1 to 100 parts by weight of cement. 5 parts by weight or less, preferably 9.5 parts by weight or less, and most preferably 0.39 to 7.1 parts by weight. In addition, in the present invention, when it is desired to increase the strength effect of a mixture of gypsum and aluminum sulfate and / or alum stone, active silicon dioxide, and alkali metal aluminate or alkali metal silicate, it can be used in combination.

The latent hydraulic material is blast furnace slag which is hardened by alkali stimulation. _ These are different from the previously mentioned active silicon dioxide, 'the particle size is almost the same as that of cement, and its powder particle size (according to the Blaine powder specific surface measurement method' void ratio 0.5) is 3000cm 2 / g ~ 8500cm 2 / g of powder, as long as the powder particle size is within this range, there is no limitation. Although its own water and activity are relatively small, when it is added together with aluminum sulfate and / or alkali metal aluminate, etc., and the previously mentioned ultrafine powder of active silica, etc., it can promote short-term strength and long-term strength. The reason is not fully understood, but it may be that water and extremely reactive aluminum sulfate or the like or alkali metal aluminate etc. are mixed with active silicon dioxide, which is easy to agglomerate and not easily dispersed, to improve the dispersion effect after being mixed in advance. The result of mixing cement and other solidified substances and showing the effect of strength, may have considerable chemical effect between the solidified substances and other ingredients. 0 重量 份 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the t side before filling out this page) These additives, such as hardening substances, are added to the cement 1 0 0 parts by weight to 0. 1 ~ 2. 0 parts by weight The best effect is that the expected effect will not be obtained when it exceeds 2 parts by weight, and it cannot be expected to have an effect when it is less than 0.01 part by weight.

Description of the invention (7) Special cement and various Brent cements are added with slag, ash, or silicon dioxide Any mixed cement can be used, and the hard cement can only shorten the working time. 'The strength effect has not been improved, so it is not suitable for use. The method for adding the cement infiltration material to the concrete or the kneading method may be a general method, and there is no particular limitation. The method for adding the cement infiltration material is generally to mix the respective powder components in advance, or The mixture is made into a suspension, which can also be added to the kneading machine when the mortar or concrete is kneaded, or the ingredients can be added separately and then mixed. In the following, the present invention will be described in more detail with examples, but the present invention is not limited by the examples. Example Γ 'In the unit amount is 360 g of water, 1000 g of cement, 1 500 g of sand, and water reduction In the mortar formed by the agent, change various types and addition amounts of gypsum, aluminum sulfate, alum stone, activated silica, etc., and adjust the fluid value within the range of 200 ± 5mm with a water reducing agent during mixing and kneading. The coagulation condition after 60 minutes of pressurized water and the compressive strength at the time of demolding after heating and curing were measured. The results are shown in Tables 1 to 3. The amount of water reducing agent is to adjust the fluid value within the range of 5 to 20 g. If the amount of aluminum sulfate or alum stone and active silica is increased, the amount of water reducing agent should be increased. The mortar mixing method is based on the mechanical mixing of IS IS R5201. Put the water into the mixing cylinder, pour the mixture of the ingredients and the cement in the low-speed mixing, stir for 30 seconds, and then pour the sand into the low-speed mixing 3 〇 This paper is applicable to Chinese National Standards (CNS) Cong Mi (21〇χ297 公 爱) (#Please read the notes on the back before filling out this page) '袈 · -1010-Printed by the Consumer Standards Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs Make A7 B7 V.

Description of the invention i: 2f) As shown in Table 7, only experiment No. 4-1 with the addition of hardened substances was added, so its strength was almost the same due to the small amount of addition. It does not have the effect of addition. In contrast, the present invention only requires 0.1 parts by weight to have the effect of addition. When the amount of addition is increased, the strength increases sequentially, but when it exceeds 2 parts by weight, the addition does not increase the expected strength effect. 》 The cement infiltrating material of the present invention with gypsum and aluminum sulfate and / or alum stone and active silica as the main components can accelerate the setting speed of mortar and concrete and shorten the pre-maturity when mixed with mortar or concrete. In time, it is possible to suppress thermal expansion cracks caused by heating and maturation and to increase the strength in a short time, and it is possible to manufacture a sand paddle or concrete that does not reduce the long-term strength. When alkali metal aluminate or alkali metal silicate is used in combination, the coagulation time can be further shortened, and the effect of suppressing thermal expansion cracking and improving the short-term strength can be improved. When using hardening materials or latent hydraulic materials together, it can increase the short-term strength and long-term strength. Therefore, for the secondary concrete products factory, the manufacturing cycle from mixing of mortar and concrete to de-framing can be shortened, and the production efficiency can be further improved.
