Effect of Stone Ash Mixture and Coconut Fiber on Concreate Compressive Strenght

Abstract

Abstract: The composition of the concrete mixture determines the compressive strength. Concrete mixtures generally consist of cement, water, coarse aggregates, fine aggregates, and concrete drugs. In this study, it will be tried to mix stone ash and coconut fibers. The purpose of this study is to find out the concrete compressive strength with add stone ash and coconut fibers to normal concrete. Data was collected through laboratory tests by carrying out an additional mixture of stone ash and coconut fibers. There were six types of specimens produced which were measured for 7, 14, 21, and 28 days. Variation of specimens 1) normal concrete, 2) normal concrete + stone ash, 3) normal concrete + coconut fiber (1.5%), 4) normal concrete + stone ash and coconut fiber (1.5%), 5) normal concrete + stone ash and 1% coconut fiber, 6) normal concrete + 1% coconut fiber. From the results of testing the concrete compressive strength was obtained 455 kg/cm2 for the age of concrete for 28 days with a mixture of normal concrete + stone ash.
