In recent years, self-compacting mortar is widely used in various parts of construction projects due to its high efficiency. The efficiency of self-compacting mortars depends on the composition used in the mixing plan and the characteristics of its components, such as the type of aggregates, super-lubricating quality, additives, etc. Also, to improve the properties of cement mortars, the use of additives such as fly ash, nano particles, etc. has become popular. Considering the importance of examining the mechanical properties and efficiency of cement mortars, in this study, the effect of microsilica and super-lubricant on the efficiency and compressive strength of self-compacting mortars has been investigated. The research results show that the addition of microsilica increases the compressive strength and reduces the small slump flow in the mortar. Also, the ratio of water to cement is one of the important parameters in increasing the short-term compressive strength, which has a greater effect than other parameters, and by reducing the ratio of water to cement, more compressive strength was obtained.
