| dc.description.abstract | The strength, nature of concrete depend on the nature of the basic material and
durability 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.
