| Abstract Scope |
The exploration of alternative materials for producing green concrete is on the rise, with promising options like pulverized waste glass and rice husk ash (RHA) gaining attention for their sustainability. This paper discusses the performance of glass and rice husk ash concrete subjected to the South African durability index test. Concrete mixtures were prepared incorporating pulverized soda lime waste glass and a blend of Portland cement and RHA as binders. The results indicated a reduction of about 52% in chloride conductivity (CCL) and 33% in the oxygen permeability index, respectively. Concrete containing a high percentage of RHA significantly decreases CCL values, indicating an increased ability to resist chloride ion transport. An optimal replacement level of 12.5% RHA is deemed suitable for structural concrete. |
