Gap-Graded Aggregate And There Advantages - Civil Knowledges

For the given aggregate/cement and water/cement ratio, the highest workability is obtained with a lower sand content in case of gap-graded aggregate. It requires less cement and lowers the water/cement ratio because of the high percentage of coarse aggregate for the same workability. Because of omission of some size, it may reduce the number of ...

This paper presents an experimental research on mechanical properties of recycled aggregate concrete (RAC) at low and high water/binder (W/B) ratios. Concrete at two W/B ratios (0.255 and 0.586) was broken into recycled concrete aggregates (RCA). A type of thermal treatment was employed to remove mortar attached to RCA. The RAC at a certain (low or high) W/B ratio was prepared with RCA made ...
