Pengaruh Kuat Tekan Beton CampuranTempurung Kemiri Sebagai Pengganti Agregat Kasar

Abstract

The strength, durability and nature of concrete depend on the nature of the basic
material, the value of the proportion of the material, the stirring method and how
it works during the pouring of the concrete mixture, as well as the compression and
selection methods during the curing process. High or low concrete performance
depends on the nature of the building blocks and the alternative materials used. The
better the nature of the specifications. The use of candlenut shell waste aims to
provide knowledge about the impact of candlenut shell waste on concrete mix. In
this research, the utilization rate of candlenut shell waste is as a gross aggregate
of 5%, 10%, 15%, 20%, and 25%. This research was carried out by testing the
concrete compressive strength specimen when the concrete was 3, 7, 14, 21, and 28
days old. From the results obtained, it can be seen that the mixture of candlenut
shells as much as 5% is the highest concrete with a compressive strength of 277.11
kg / cm2 when the concrete reaches the age of 28 days. As a result of testing,
concrete with the addition of candlenut shell waste affects concrete from concrete
reaching the age of 3 days until the concrete is 28 days old. As a result the best
concrete mix for construction work.
