More Information
Summary:The invention discloses compression-resistant mortar and a preparation method thereof. The method comprises the following steps: mixing fine sand, yellow sand and vitrified microbeads, adding the obtained mixture into a ball mill for wet grinding for 4 to 12 hours; mixing bentonite, a sodium silicate aqueous solution, ferric oxide, alkylbenzenesulfonic acid, sodium lignin sulfonate and a melamine-serial water reducing agent, and conducting even dispersing; slowing adding the mixed dispersion to mortar slurry, and then placing the obtained mixture in a double-shaft horizontal stirring kettle, and conducting even stirring, wherein the stirring speed is 300 to 400 r/min, and the stirring time is 1 to 2 hours. The added alkylbenzenesulfonic acid can increase the compressive strength and flexural strength of the mortar of the present invention. An appropriate amount of water is added to the milled mixture to make the resulting mortar having a water content of 33-35%. Controlling the moisture content of the mortar
