You want to increase the sustainability of a concrete mixture by replacing 35% of the portland cement by mass with a locally available natural pozzolan that can be used in place of ordinary portland cement (CEMPOZZ). The quantity of cement in the concrete mixture is 620 lb/yd3. You can assume that the specific gravity of portland cement and CEMPOZZ are the same for this problem. What is the quantity of CEMPOZZ for the mixture? Round to the nearest whole number and do not include units when entering your answer.
