Investigation Into the Suitability of Sand and Gravel Materials Commonly Used in Building Construction

Abstract

This report comprises the use of aggregate both fine and coarse aggregate in the production of concrete, these coarse aggregate are strong in compressive strength of concrete. The coarse and fine aggregate that possess both physical and mechanical properties in the production of concrete which in a correct proportion to give desire strength of the concrete. The mixing ratio that was used is 1:2:4 which known as pure mixing and the other ratio is ratio 1:3:6. 1:2:4 gives 1 head pan of cement with 2 head pan of sharp sand or fine aggregate while 4 head pan for coarse aggregate. After the production of the casted cube, curing was carried out. The duration of the curing is 7 days, 14 days, 28 days. After the curing days, compressive strength test was performed to determine the suitability of the sand and gravel materials in the strength of concrete generally used in the building construction.
