Experimental study on long-term compressive strength of concrete with manufactured sand

In this paper, experimental studies on compressive strength development of concrete with manufactured sand were carried out. Influences of stone powder content on long-term compressive strength of concrete with different water-to-cement ratios were analyzed. Tests results showed that when content of stone powder was less than 13%, it basically had positive correlation with the long-term compressive strength of MSC. Based on tests data, forecast model of long-term compressive strength of MSC considering curing age, water-to-cement ratio and cement's compressive strength and density are proposed.
