Determine the batch weights needed for all materials for a 1yd^3 batch yielding an f'c= 2500 psi given the following information.
•slump = 5 inch max
•w/c = .55
•cementitious content = 675 lbs
•fly ash content= 30% by weight
•fly ash specific gravity= 2.8
•CA (limestone) specific gravity (SSD) = 2.578
• FA (sand) specific gravity (SSD) = 2.654
• cement( type 1) specific gravity = 3.14
•air content = 4% ( air entrained)
•coarse aggregate absorption = 2.4%
•coarse aggregate moisture content = 1.6%
•fine aggregate absorption= .8%
•fine aggregate moisture content = 2.8%
•58 % coarse aggregate
•42% fine aggregate
