Compressive strength of high-strength concrete with cornice adhesive as a partial replacement for cement

Abstract

Concrete was made from a mixture of water, cement, and aggregate with a ratio depending on the type of concrete. The purpose of this study was to determine the effect of using Cornice Adhesive as a partial replacement of cement on the compressive strength. Variations of cornice adhesive used were 0%, 5%, 10%, and 15% replacing cement. The compressive strength test was used to evaluate the mechanical characteristics of the concrete produced at 3 days, 7 days, 14 days, and 28 days. The results showed that cornice adhesive makes a positive contribution to the weight loss of concrete and can be used to reduce the weight of the structure. Although for the compressive strength value of the concrete mixture using Cornice Adhesive as a partial replacement of cement with variations of 5%, 10%, and 15% at the age of 3 days, 7 days, and 28 days could not exceed normal concrete (0% cornice adhesive). However, the biggest increase in compressive strength value from 3 days to 28 days is using a concrete mixture with a variation of 10% cornice adhesive as a replacement for cement, up to 70.4% increase.
