Abstract

The objective of this study is to analyze the degree of surface-glossing of cement mortar with the grading of aggregate and contents of limestone powder. According to the experimental results, degree of surface-glossing of cement mortar using river sand is higher than that of crushed sand. As F.M of aggregates is less than 2.78, degree surface-flossing of cement mortar has better performance, Also, as the contents of limestone power increase, degree of surface-flossing is shown to be improved, And it shows that degree of surface-glossing decrease with elapse of age.
