Abstract
Studies show that mortar and concrete are used as the main materials in more than 80% of technologies. Therefore, pay attention how to increase workability and improve performance required of mortar and concrete. Mortar can be made in numerous ways, but studies have shown that the ready mixed mortar has many advantages compared to others, but without quality control and production monitoring, the customer confidence would be missed. The aim of this study is to investigate the possibility of using specialized sand in the factory for making mosaic mortar mix and controlling mortar properties. In this study, mortar specimens were created by specialized sand for making mosaic, and ordinary sand in different ratio of cement to sand. Also, specimens were produced by the ready mix mortar. The results of the compressive strength and water retention of mortar, the comparisons of fracture specimens and scanning electron microscope (SEM) images showed the possibility of using specialized sand mosaic in the production of dry mortar.
