Background
In the key period of high-quality development of the economic society in China, the demand of important infrastructure and large-scale town construction on concrete materials, especially cement materials, is huge. According to the statistics of the national statistical bureau, the 2022 national cement yield is 21.2 hundred million tons, and the cement production needs to consume a large amount of energy and resources and release a large amount of CO 2 And dust, causing serious pollution to the environment. Therefore, reducing the amount of cement in concrete while ensuring that the concrete strength is met is a significant topic of current social and economic development.
At present, the problem of large concrete slump loss is particularly serious in the concrete construction process in many areas of China. Constructors are used to directly add water into the concrete to increase the flowability of the concrete, so that the strength of the concrete is reduced, the durability of the concrete is reduced sharply, engineering hidden danger is greatly increased, and the service life of the engineering is greatly shortened. In order to enhance the strength and fluidity of concrete, researchers have developed various water reducers excellent in performance, and proposed a concept of a slurry admixture having a water reducing function. At present, the slurry admixture in China pays attention to the development of the water reducing function, and has low attention to the segregation and bleeding phenomenon and slump loss phenomenon of concrete. Therefore, it is necessary to develop an additive with reinforcing and slump retaining functions to improve the performance of concrete.
Disclosure of Invention
In view of the above, the present invention aims to provide a method for preparing a slurry admixture with reinforcing and slump retaining functions, so as to solve the problem of poor reinforcing and slump retaining effects of the existing slurry admixture.
In order to achieve the above purpose, the technical scheme of the invention is realized as follows:
a preparation method of slurry admixture with reinforcing and slump retaining functions comprises the following steps:
1) Mixing 63-79 parts of zeolite, 0.7-1.3 parts of grinding aid and 42-57 parts of water according to parts by weight, and carrying out superfine treatment on the zeolite by adopting a wet grinding process to obtain superfine zeolite slurry;
2) Adding 5.9-8.3 parts of polymerization precursor into the superfine zeolite slurry, uniformly stirring, then adding 0.06-0.13 part of ammonium persulfate, and carrying out in-situ polymerization under certain conditions to obtain the slurry admixture with the functions of enhancing and retaining slump.
Optionally, in step 1), the grinding aid is a mixture of sodium tripolyphosphate and sodium hexametaphosphate, and the mass ratio of the sodium tripolyphosphate to the sodium hexametaphosphate is (0.6-1.2): (1.1-1.5).
Optionally, the wet grinding process in step 1) has a wet grinding speed of 23-29rpm and a wet grinding time of 30-45min.
Optionally, the grinding medium of the wet grinding process in step 1) is a zirconia grinding body; the zirconia grinding body has a mass which is 3 times that of the zeolite, and the grading of the zirconia grinding body is 10 mm:8 mm:5 mm:3 mm=1:4:4:1.
Optionally, the ultrafine zeolite slurry in step 1) has a median particle size of 6-10 μm and a water content of 50% -70%.
Optionally, the polymerization precursor in the step 2) is a mixture of acrylic acid, hydroxyethyl acrylate and methyl allyl polyoxyethylene ether, and the mass ratio of the acrylic acid to the hydroxyethyl acrylate to the methyl allyl polyoxyethylene ether is (0.3-0.4) to (0.6-0.8) to 10.
Alternatively, the reaction temperature of the in-situ polymerization reaction in step 2) is 50-60 ℃ and the reaction time is 3-4h.
The second object of the present invention is to provide a slurry admixture with reinforcing and slump retaining functions, which is prepared by the above method.
The third object of the invention is to provide an application of the slurry admixture with the reinforcing and slump retaining functions in cement concrete, wherein the mixing amount of the slurry admixture with the reinforcing and slump retaining functions is 5-10% of the dosage of the cementing material of the cement concrete.
The preparation mechanism of the invention:
the invention takes zeolite and water as main materialsThe slurry admixture with the functions of enhancing and retaining slump is prepared from raw materials by wet milling technology and in-situ polymerization under the action of a polymerization precursor, ammonium persulfate and a grinding aid. Wherein, the wet grinding process introduces water molecules in the grinding process, reduces the surface energy of particles, and prevents the possible agglomeration phenomenon of particles in the conventional grinding process. Ultrafine treatment is carried out on zeolite to obtain zeolite particles with particle size smaller than that of conventional grinding, which is beneficial to the calcium (OH) provided in the hydration process of active silicon and active aluminum occluded in zeolite and cement 2 Secondary reaction occurs to generate more hydration products, so that the strength is improved. In addition, the polymerization precursor interacts with an initiator to perform in-situ polymerization reaction to synthesize the slow-release slump retaining agent with ester groups. Because the zeolite is porous and has excellent adsorption performance, ultrafine zeolite is used as a carrier to adsorb the slump retaining agent generated by in-situ polymerization reaction, and the aim of slow-release slump retaining can be realized. Under the synergistic slow release effect of the two, the cement paste can still keep good fluidity in the later stage of hydration, and the requirements of ultra-long distance and ultra-high pumping construction are met.
Compared with the prior art, the slurry admixture with the functions of enhancing and retaining slump has the following advantages:
1. the slurry admixture with the functions of reinforcing and slump retaining is prepared by an in-situ polymerization method, so that the preparation process is effectively simplified, the production cost is reduced, and the slurry admixture can partially replace cement slurry and is directly used for producing building materials. When the cement paste is used for cement concrete in the mixing amount of 5-10%, the fluidity of the cement paste is increased by 30% in 1h, the fluidity is increased by 20% in 2h, and no loss is caused in 3 h; the 1d compressive strength is improved by 5 percent, and the 28d compressive strength is not reduced.
