Abstract

The main objective of this research goal is to investigate the impact behavior of cockle calm as fine aggregate in concrete under drop weight impact test. In this study,cockle calm is used in the ratio of 0%, 10%, 20% and 30% in the weight of fine aggregate in concrete matrix. Water Cement ratio was 0.42 for compressive test and drop weight impact test. Four slabs were casted in the dimension of 500mmX500mmX50mm and 6mm diametersteel bars were used with 90mm center to center spacing. The Impact testing machine was self-fabricated. The test results indicate the failure pattern of the slab by visible observation of First crack and final crack occur in the slab. The cracks length, width, depth were observed in every blows.
