레디믹스드콘크리트의 조합설계안 분석보고

This report presents the survey findings on the proportioning of ready mixed, concrete mixtures. According to this report, the W/C ratio and S/A ratio, based upon the type 25-210-12, in mix proportion of ready mixed concrete are 53% and 45% respectively. The problems to be improved, coming out in this study, are (1)using the adequate quantity of cement (2) alternation of mix design cope with the change of kinds of aggregates (3)large standard error in the mix proportion.
