A Case Study of Placed Remicon in "S" Apartment

This subject,'S" apartment structural frame has not been achieved without considerable effort by all quality controller involved. Therefore, it is appropriate at this time to report by all the fact of concrete quality control in our site. These are emphasized that the average strength of placed concrete must always exceed the specified value of design strength used in the structural design phase. In general, quality of ready mixed concrete largely depends not only upon the manner of production and proper observance of recognized methods of placement, finishing, curing, transportation etc. ,but also many kinds of influential factors even more handling of the test procedure, As this practical report, approaching to judgement by analysis of sampled specimens in site weather placed concrete have satisfied quality compare the specified strength with the target strength which is applied to standard deviation related with influential factors as above mentioned. This case study is consist of 1) A foreword, 2) Site brief, 3) A precondition for analysis, 4) A formulas derivation and quality analysis, 5) Economic gains by the coefRcient of increase and 6) A conclusion.sion.
