Building mortar and preparation process thereof
The invention belongs to the technical field of building materials, and particularly relates to building mortar and a preparation process thereof. The building mortar comprises the following components in parts by weight: 40 parts of cement; 30 parts of coal gangue; 18 parts of bentonite fine powder; 4 parts of a mortar activator; and 8 parts of glass fiber powder; the coal gangue is naturally orartificially combusted coal gangue; wherein the bentonite fine powder is sodium bentonite fine powder; the process comprises the following steps: S1, preparing raw materials; S2, feeding the raw material; S3, mixing the raw materials. The phenomenon that when dry-mixed mortar is poured into an aqueous solution to form a mortar solvent, the mixed dry-mixed mortar is dispersed by the aqueous solution due to poor adsorption cohesiveness after mixing of the dry-mixed mortar, the mutual cohesiveness between building mortar is affected, the anti-cracking and anti-seepage effects are achieved, and the service life of the building mortar is prolonged is effectively prevented.
本发明属于建筑材料技术领域，具体的说是一种建筑砂浆及其制备工艺；各组分的重量成分为：水泥：40份；煤矸石：30份；膨润土细粉：18份；砂浆活化剂：4份；玻璃纤维粉：8份；煤矸石采用自然或人工燃烧过的煤矸石；膨润土细粉采用钠质膨润土细粉；该工艺包括如下步骤：S1：原料制备；S2：原料投放；S3：原料混合；有效防止干混砂浆在倒入水溶液形成砂浆溶剂时，由于干混砂浆之间混合后的吸附粘结性较差，进而导致水溶液将混合后的干混砂浆进行冲散的现象，进而影响建筑砂浆之间的相互粘结性，且抗裂变防渗效果，提高建筑砂浆的使用寿命。
