Abstract

Compressive strength and flexural strength are two important parameters in the concrete job mix formula. Both parameters are strongly influenced by the characteristics of the constituent aggregates. This study aims to obtain the relationship between the compressive strength and flexural strength of concrete mixtures using local aggregates for construction projects around the province of South Kalimantan. The experimental mechanism was carried out by examining aggregates and designing concrete proportions using type V Portland cement with an initial setting time of 80 minutes and a final setting time of 150 minutes. Meanwhile, coarse aggregate from Katunun and fine aggregate from Barito are used in the concrete job mix formula. In this case, the results of the analysis show that there is a correlation value (K) for f'c 30 MPa and f'c 35 MPa, which are 0.84 and 0.78, respectively.
