Abstract
The development of green technology requires the utilization of waste products and processing of them into cheap and environmentally friendly materials. The idea was applied in the concrete block (conblock) production. The usage of coconut shell waste for the concrete mixed material will reduce the cost and produce an environmentally friendly road conblock for pavement, which also quickly absorbs runoff into the soil so that pavement is more durable.The purpose of this research was to evaluate the compressive strength of concrete obtained by the addition of fine aggregate mixture and a coarse aggregate of coconut shell. The test specimens used were cubes with a size of 15x15x15 cm consisting of 5 samples for each variation of coconut shell and powder content (0%, 20%, 25%, and 30%) and tested at 28 days.The average yield of compressive strength and absorption at 28 days were 18.5 MPa and 22% for 0% variation, 11.4 MPa and 16% for 20% variation, 7.6 MPa and 14% for 25% variation, and 6.7 MPa and 12% for 30% variation. The results inform that the concrete given a mixture of fine and coarse aggregate coconut shell has decreasing compressive strength and absorption.
