The factors affecting the strength of the mortar are: When the quality of the raw materials is constant, the strength of the mortar depends mainly on the cement number and the amount of cement. In addition, mortar strength is also related to sand, admixtures, blended materials, and masonry and curing conditions. When sand contains mud and other impurities, mortar strength is also affected.
For the various technical properties of mortar, the application of magnesium aluminum silicate thixotropic lubricant in mortar has the following advantages:
Excellent workability and processability: it can extend the open time and operating time of mortar and paste, increase the lubricity of mortar and paste, reduce the stickiness of knife, and increase work efficiency and labor productivity;
Improve sag resistance: The yield value can make the surface of the mortar and paste more full, smooth and reduce the loss of mortar
Good thixotropy: it can save labor during construction, increase construction efficiency, and reduce labor costs;
Good anti-settling performance: reduce the settlement and stratification of floor and self-flowing flat cement, and make the same structure;
Storage stability: It can make the mortar homogeneous and stable, prevent stratification and water precipitation; improve pumpability and shear thinning: reduce the friction between cement and sand, with a smooth effect, make the mortar easy to pump When the shear force overcomes the yield value, the flow viscosity of the mortar can be reduced, so that the pumping is more convenient and the transportation efficiency is improved, thereby reducing the overall cost.
