Stone powder and machine-made sand compound mortar and preparation method thereof
The invention aims to crush the crushed high-calcium stones to obtain the machine-made sand and the stone powder, and based on the obtained machine-made sand and the stone powder, the cement, the mineral powder, the fly ash, the water and the additive are doped to obtain the stone powder and machine-made sand compound mortar. According to the stone powder and machine-made sand compound mortar prepared by the invention, the stone powder is added into the mortar, so that the water consumption can be reduced, and meanwhile, the compressive strength of the mortar can also be improved; the stone powder can enhance the bonding effect of the mortar, reduces the cost of the mortar, and is suitable for industrial production.
本申请旨在将经过破碎时的高钙石子进行破碎，得到机制砂和石粉，基于得到的机制砂和石粉，掺入水泥、矿粉、粉煤灰、以及水和外加剂即得到石粉与机制砂复配砂浆。本申请制备而得的石粉与机制砂复配砂浆，该砂浆内加入石粉，能减少用水量，同时还能增加砂浆的抗压强度；石粉还能增强砂浆的粘结作用，降低了砂浆的成本，适于工业生产。
