Abstract

In this paper, different rocks like marble, calcite, basalt, granite and quartz were used to produce the sand of CA mortar. Results showed that the type of sand had notable effects on the mechanical properties of CA mortar. For the calcium carbonate composition rocks like marble and calcite, when use the anion emulsified asphalt, the compressive strength and water resistance of CA mortar were higher than those of used the cation emulsified asphalt. But for the silica composition rocks like basalt, granite and quartz, the rule had reversed. Those may have the relationship with the charge type of the sand. Results also showed that for both of the anion and cation emulsified asphalt, when used the marble based sand, the compressive strengthwere very low. This paper may have some significance for the selection of the emulsified asphalt and sand of CA mortar.
