CALIBRATING THE DENSITY OF CONCRETE FROM WASHED AND UNWASHED LOCALLY 3/8 GRAVEL MATERIAL AT VARIOUS CURING AGE [ ]


Concrete densities were calibrated at different water cement ratios and curing age, the study expressed the rate of fresh mix cement design with locally occurring 3/8 gravel to monitor its performance base on these conditions, the densities calibrated expresses model equations from washed and washed gravel as it characterized. The results express concrete densities at different water cement ratios and curing age, the variations are base on mix proportion thus variation on compactions, most results calibrated express variations base on the influences from mix proportion and compactions, other influence are impurities from unwashed 3/8 gravel, it express some variation of densities from graphical representation, these affect the densities of concrete as it express in various curing age, the developed model will be apply to predict the densities of concrete to determine variations of concrete performance.
