Concrete water-retaining agent and preparation method thereof and concrete using concrete water-retaining agent
The invention relates to a concrete water-retaining agent and a preparation method thereof and concrete using the concrete water-retaining agent, and belongs to the technical field of concrete admixtures; the concrete water-retaining agent comprises 20-30 parts of polycarboxylic acid, 2-6 parts of tea saponin, 10-20 parts of cellulose ether, 5-14 parts of dispersible latex powder, and 30-40 parts of an inorganic water-absorbing material. The preparation method of the water-retaining agent comprises the step of uniformly mixing the raw materials to obtain the water-retaining agent. The water retention performance of the concrete can be improved, and the self-drying shrinkage problem of the concrete is solved.
本申请涉及一种混凝土保水剂及其制备方法和使用其的混凝土，属于混凝土外加剂技术领域，其包括聚羧酸20‑30份、茶皂素2‑6份、纤维素醚10‑20份、可分散乳胶粉5‑14份、无机吸水材料30‑40份。该保水剂的制备方法：将上述原料混合均匀即得保水剂。本申请能够提高混凝土的保水性能，解决混凝土的自干燥收缩问题。
