Abstract:
The amount of fly ash waste is increasing, causing environmental and storage problems. One solution is to utilize the fly ash as an artificial aggregate. This research focuses on getting the right formula for mixing fly ash, cement, and superplasticizer (SP). The tests carried out were compressive strength at 3, 14, 28, and 56 days. The results showed that the best composition with a ratio of cement: fly ash of 1:4 added with a superplasticizer of 1.2% by weight of the mixture resulted in a compressive strength of 79 MPa at 56 days of age.
