Abstract:

In this study, the concrete consists of a mixture of self-curing agent, bottom ash, superplasticizer, water and cement. By adding self-curing agent in concrete, it can reduce water evaporation effect and therefore increase the water retention capacity of concrete compared with conventional concrete, which leads to, improved compressive strength. Bottom ash is the residue that is not capable of burning attached to the wall of the combustion process in the furnace. In previous studies, outcomes showed that the introduction of bottom ash to concrete could increase the level of hydration and compressive strength. The trend of self-curing concrete will be analyzed in detail. Furthermore, the lab scale testing will be conducted to determine the workability and mechanical properties by varying the percentage of self-curing agent and bottom ash. The results reveal that Polyethylene Glycol (PEG) increase concrete workability and compressive strength compared to control mix. This promising result shows the potential of producing self-curing concrete using bottom ash.
