Influences of Quality of Aggregate on the Properties of Cement Mortars in Floors Using Expansion Agent
초록
In this paper, physical properties of fresh and hardened mortar for floor using expansion agent are described under various grain shape, grading and chloride contents of aggregates. According to experimental results, as fineness modulous increase, fluidity show high it also shows high with cement mortar using riversand and continuous distribution of grading. We can not detect any difference in fluidity according to chloride contents. Air content shows to be decreased with crushed stone having large fineness modulous and continuous distribute on of grading. chloride content does not influence on the air content. compressive strength tends to increase when crushed sand with continuous distribution of grading is used and chloride contents decreases.
