Concrete internal curing agent as well as preparation method and application thereof
The invention relates to the technical field of concrete, in particular to a concrete internal curing agent as well as a preparation method and application thereof. The preparation method of the concrete internal curing agent comprises the following steps: performing in-situ polymerization, crushing and drying on a mixture of foam concrete and a polymer precursor solution to obtain the concrete internal curing agent, the mass ratio of the foam concrete to the polymer precursor solution is 1: (0.4-1.5); the polymer precursor solution comprises an unsaturated monomer, a cross-linking agent, an initiator, a coupling agent and water; the volume weight of the foam concrete is 400 to 1000g/L. The inorganic raw materials and the organic raw materials adopted by the concrete internal curing agent are regulated and controlled, in-situ polymer is carried out, the prepared concrete internal curing agent has the water absorption performance, and the shrinkage resistance and the compressive strength of concrete are improved.
本发明涉及混凝土技术领域，尤其是涉及一种混凝土内养护剂及其制备方法和应用。混凝土内养护剂的制备方法，包括如下步骤：泡沫混凝土与聚合物前驱体溶液的混合物进行原位聚合，破碎、干燥，得到所述混凝土内养护剂；所述泡沫混凝土与所述聚合物前驱体溶液的质量比为1﹕(0.4～1.5)；所述聚合物前驱体溶液包括不饱和单体、交联剂、引发剂、偶联剂和水；所述泡沫混凝土的容重为400～1000g/L。本发明通过调控混凝土内养护剂所采用的无机原料和有机原料，进行原位聚合物，制得的混凝土内养护剂可兼顾吸水性能，并提高混凝土的抗收缩性能和抗压强度。
