Question
If 75% of the natural coarse aggregate (NA) is replaced with recycled coarse aggregate (RCA) on a volume basis, calculate the RCA and NA contents
If 75% of the natural coarse aggregate (NA) is replaced with recycled coarse aggregate (RCA) on a volume basis, calculate the RCA and NA contents in kg. Assume the RCA's SSD density is 25% lower than that of NA. What is the wet density of this concrete?
NA's SSD density = 2.73x10^3kg/m^3
Fresh concrete wet density only with NA = 2415.09kg/m^3
