Anti-crack waterproof composite additive for concrete as well as preparation method and application of anti-crack waterproof composite additive
The invention discloses an anti-crack waterproof composite additive for concrete as well as a preparation method and application of the anti-crack waterproof composite additive. The anti-crack waterproof composite additive for concrete is prepared from the following components in parts by weight: 30 to 40 parts of mica powder, 10 to 20 parts of attapulgite powder, 3 to 5 parts of coupling agent, 10 to 20 parts of polyamide fiber, 5 to 10 parts of sodium 4-cumenesulfonate, 10 to 15 parts of sodium dodecyl benzene sulfonate, 2 to 4 parts of ammonium sulfate, 1 to 2 parts of carboxymethyl cellulose ether and 12 to 15 parts of calcium sulphoaluminate. According to the anti-cracking and waterproof composite additive for the concrete, the raw materials are compounded, when the anti-cracking and waterproof composite additive for the concrete is added into the concrete, gaps in a concrete matrix can be filled, various complex reactions are carried out, anisotropy among the raw materials is reduced, then the anti-cracking and waterproof performance of the prepared concrete is improved, and the application field of the concrete is remarkably widened.
本发明公开了一种混凝土用抗裂防水复合添加剂及其制备方法和应用，所述混凝土用抗裂防水复合添加剂由如下重量份组分组成：云母粉30～40份、凹凸棒粉10～20份、偶联剂3～5份、聚酰胺纤维10～20份、4‑异丙苯磺酸钠5～10份、十二烷基苯磺酸钠10～15份、硫酸铵2～4份、羧甲基纤维素醚1～2份和硫铝酸钙12～15份；本发明混凝土用抗裂防水复合添加剂通过各原料复配，当添加到混凝土中时，能够填充混凝土基体内的空隙，同时进行各种复杂反应，降低各原料间的各向异性，进而提高制备混凝土的抗裂和防水性能，显著提高了混凝土的应用领域。
