Abstract

The use of recycled coarse aggregate (RCA) could be an alternative solution to the scarcity of natural aggregates as a concrete material and also the problem of construction waste. This paper aim is to analyze the model of compressive stress-strain curve of recycled aggregate concretes based on the literature review using the statistical approach. Database of existing experimental tests from different researchers consists 124 test specimens that come from 25 previous published journal articles. The specimens was selected based on the proportion of RCA mixtures that been used which are 50% and 100% of the concrete aggregates. This research was using simple linear regression analysis method with Statistical Package for The Social Sciences (SPSS) software. The data of the specimen analysis was differentiated into three stages of analysis, namely the analysis for the whole group data specimens, the group of concrete specimens without any additives, and specimens that use additives. The results show that the significant value from the data analysis was lower than 0.05, which are the limit values for significant value of the data analysis. This means that the water-cement ratio has the influence to the compressive strength of RCA concrete mix.
