Hear one of our Emerging Engineer finalists, Maxime Van Crombrugge, talk about his research on the impact of a rice husk ash (RHA) and laterite as alternative construction materials in the production of concrete roof tiles.

In his investigation, RHA was used as a 15% partial substitute for cement in the concrete mix and acted as the control sample.

Different percentiles of laterite were incorporated as partial substitution for sand in the fresh concrete at 10%, 25% and 50%. A total of 78 samples were cast and cured, consisting of 24 cubes and 54 tiles, to evaluate laterite concrete’s 7-day and 28-day compressive strengths, 7-day and 28-day flexural strengths, and 28-day water absorption and water permeability.
