て来ている。2. Description of the Related Art Conventionally, concrete has been widely used as a floor material for buildings and outdoor facilities. However, when using these conventional ones, for example, in parks, sidewalks of hills, poolside, underpasses, baths, parking lots, station yards, etc., there is no water permeability, i.e., no water absorption or drainage. There have been various drawbacks, such as the formation of water pools on the surface, which makes the vehicle slippery, and the lack of sound absorption causes noise from passing vehicles. In recent years, accidents caused by the above-mentioned defects have frequently occurred, and this has become a serious social problem.

防止に役立つ。[Problems to be Solved by the Invention] The material of the high-strength water-permeable concrete of the present invention is a commonly used material for concrete.
The main material is crushed stone having a relatively narrow range within the particle size range of the crushed stone and the crushed stone. In order to impart strength after molding to the crushed stone material sized to a predetermined particle size, one or two or more of known inorganic binders and organic binders are used in an amount of 0.4 to 0.5% with respect to cement. Add. If the amount of water to be added exceeds 0.5 part by weight per 1 part by weight of cement, the water permeability of concrete deteriorates, while
When the amount is less than parts by weight, it is difficult to perform sufficient kneading.
It was determined to be 0.27 parts by weight. Adding a ceramic pigment or using a color glaze for the purpose of coloring the product is effective in enhancing the aesthetics after the product is installed. Also, by adding 0.4 to 0.5 parts by weight of special binder to cement, the strength exceeds that of ordinary concrete secondary products. By limiting the aggregate to No. 7 crushed stone and No. 6 crushed stone, the interparticle space between the material particles is controlled, whereby the porosity is 10 to 13% and the water permeability is 0.17 Cm.
/ Sec or more. In addition, No. 7 crushed stone, 6
By using the crushed stone, the surface condition of the product can be made uniform and rough, whereby the coefficient of friction of the surface can be increased and the slip caused by water can be reduced. Further, by setting the porosity to 10 to 15%, the incident sound absorption coefficient becomes 700.
An effect of 60% or more is obtained at 5,000 Hz, which helps to prevent noise.

透水性や高強度の経年変化も極めて少ない。[Means for Solving the Problems] As the cementitious substance used in the present invention, various kinds of ordinary, early-strength, ultra-high-strength and white Portland cement are used. Further, low heat cement, sulfate resistant cement, alumina cement and the like can also be used. In the present invention, the aggregate refers to a crushed stone No. 7 or a crushed stone No. 6, and it is preferable to use an aggregate selected according to a rule having a Mohs hardness of 6 or more or a Knoop indenter hardness of 700 Kgf / mm 2 or more in terms of strength. . Thereby, when molded in a pressurized state, a permeable concrete having a high porosity filling structure and high strength can be manufactured. Examples of inorganic binders used as the binder include porcelain powder such as anhydrous gypsum powder, kaolin and feldspar, blast-furnace granulated slag powder, powder discharged from a silica stone manufacturing plant, and various alumina-based compound powders. Various resins can be used in the form of latex as the organic binder. Further, formalin polymers are also suitable. These are indispensable additives for maintaining high strength, and the mixing range is 0.4 to 0.5% with respect to cement. The ratio of cement to water (W / C) is one of the major factors that determine the performance of permeable concrete. If W / C is small, the bonding between the aggregates is weakened, and the strength becomes practically insufficient.
On the other hand, if W / C is too large, the gap between the aggregates is filled with cement, and the water permeability becomes insufficient. Therefore, in the present invention, W / C is set to 0.24 to 0.27. According to this value, the product has high water permeability and sufficient bending strength, and its water permeability and high strength change over time is extremely small.

ものである。[Action] The product obtained according to the present invention exhibited high strength and excellent water permeability. The product of the present invention had a water permeability coefficient of 0.16 to 0.17 Cm / sec with respect to the water permeability interlocking standard of 0.01 Cm / sec. In the compression strength test (28 days of material age), it was 150 kgf / Cm 2 or more, and in the bending strength test, it was 49.1 kgf / Cm 2 (pavement design standard: 45 kgf / Cm 2 ), and each test reached the reference value. The porosity of the product of the present invention is 12% to 6-8.
It seems that the strength test value is further increased by lowering the strength test value. Therefore, from the above test results, it is an excellent product that can be sufficiently used as an interlocking block and for concrete pavement, and is practically used as a product that is kind to nature, protects groundwater, and considers natural ecosystems. .
