Anti-seepage and anti-crack cement mortar material and preparation method thereof
The invention discloses an anti-seepage and anti-crack cement mortar material and a preparation method thereof. The anti-seepage and anti-crack cement mortar material is prepared from the following substances in parts by mass: 200 to 300 parts of cement, 8 to 18 parts of bentonite, 500 to 750 parts of sand, 0.2 to 1.8 parts of basalt fiber, 2 to 3 parts of a water reducing agent and 100 to 150 parts of water. The preparation method comprises the following steps: step 1, mixing 200 to 300 parts of cement, 8 to 18 parts of bentonite and 500 to 750 parts of sand at a speed of 140 to 160 r/min, and carrying out dry stirring for 3 minutes; 2, 0.2-1.8 parts of basalt fibers are added into the mixed dry mixture obtained in the step 1, and dry mixing is conducted for 5 min at the speed of 140-160 r/min till the basalt fibers are completely dispersed; 3, adding 100-150 parts of water in which 2-3 parts of a water reducing agent is dissolved into the mixed dry mixture in the step 2, and carrying out wet mixing at the speed of 140-160r/min for 10 minutes; and 4, molding and pouring the test piece, and curing in a standard curing box to the age. The anti-permeability performance grade of the prepared cement mortar reaches P8 grade or above, the crack limiting grade reaches I grade, and the cement mortar conforms to national relevant safety and performance index regulations.
本发明公开了一种防渗抗裂的水泥砂浆材料及其制备方法。防渗抗裂的水泥砂浆材料包括下列质量份的物质：水泥200～300份、膨润土8～18份、砂500～750份、玄武岩纤维0.2～1.8份、减水剂2～3份，水100～150份。所述的制备方法包括以下步骤：步骤1：将200～300份的水泥、8～18份的膨润土、500～750份的砂以140～160r/min的速度混合干拌3min；步骤2：再将0.2～1.8份的玄武岩纤维加入步骤1所述混合干拌物中，以140～160r/min的速度干拌5min至完全分散；步骤3：将溶有2～3份的减水剂的水加入至步骤2所述混合干拌物中，水的份数为100～150，以140～160r/min的速度湿拌10min；步骤4：试件成型浇筑并标准养护箱中养护至龄期。本发明制备的水泥砂浆的抗渗性能等级达到P8级以上，限裂等级达到I级，符合国家相关安全与性能指标的规定。
