Concrete Compressive Strength Test Using Ancol Maras Beach Stone South Bengkulu as Coarse Aggregate in Concrete Mixes

Abstract

Concrete is a widely used material and is the main element in buildings. One of the main components in the manufacture of concrete is coarse aggregate, coarse aggregate has a very large role in determining the compressive strength of concrete, this is because coarse aggregate is the largest component in the percentage of concrete constituent materials. The purpose of this research is to find out whether ancol beach stone can be a coarse aggregate and meet the standards as a concrete material with fc' 25 Mpa. Based on the research that has been done, it is found that the normal concrete mixture using ancol beach stone by 40% with a curing age of 28 days has an optimal compressive strength value of 35.9846 Mpa. From the research that has been done, it can be concluded that ancol beach stone can be used as alternative for coarse aggregate in concrete.
