Abstract: The aim of this study is to investigate the characteristics exhibited by three different grades of concrete using mix design approach. From the result of the sieve analysis, it shows that the sands used for the experiment is a well graded sand of zone 1 of BS882

When most contractors think about concrete mix design—if they think about it at all—the first thing that comes to mind is "bags" or "sacks." In the old days, when most concrete was mixed on site, cement was purchased in bags. A bag is 94 pounds of cement, or about 1 cubic foot; but if you order a 6-sack mix, all that tells you is how much portland cement is in the mix. That mix could be ...
