Adhesive mortar special for inorganic quartzite and preparation method of adhesive mortar
The invention provides special adhesive mortar for inorganic quartz stone and a preparation method of the special adhesive mortar. The adhesive mortar specifically comprises Portland cement, heavy calcium powder, fine aggregate, redispersible latex powder, cellulose ether, hybrid fibers and a functional additive. Wherein the functional additive is formed by compounding an organic silicon defoaming agent, an alkyl sulfate air entraining agent, a polycarboxylic acid water reducing agent and an organic silicon water repellent according to the mass ratio of 1: 1: 2: 2. The adhesive mortar has the advantages of excellent physical and mechanical properties, fast development of early strength, high strength, high bonding strength, low water absorption rate and shrinkage rate, good flexibility and impact resistance and good constructability, is especially suitable for large-area paving engineering of large-size inorganic quartz stone, has excellent efficiency under the action of different humid and hot environment factors, and has good application prospects. The long-term safe service effect can be achieved, and the engineering quality is ensured.
本发明提供一种无机石英石专用粘结砂浆及其制备方法。该粘结砂浆具体包括硅酸盐水泥、重钙粉、细骨料、可再分散乳胶粉、纤维素醚、混杂纤维和功能添加剂。其中，功能添加剂为有机硅消泡剂、烷基硫酸盐引气剂、聚羧酸减水剂、有机硅憎水剂按照1：1：2：2的质量比复配而成。该粘结砂浆具有优良的物理力学性能，早期强度发展较快且强度较高，粘结强度高，吸水率和收缩率低，柔韧性和抗冲击性能好，具有良好的可施工性，尤其适用于大尺寸的无机石英石大面积铺贴工程，且在不同湿热环境因素作用下效能优异，可实现长期安全服役效果，确保工程质量。
