The study, co-authored by an AURAK researcher, used Machine Learning techniques to develop strength prediction models

Ras Al Khaimah, UAE, June 27, 2024: As part of quest for substitutes for cement in the construction industry, a group of researchers from ten universities – including the American University of Ras Al Khaimah (AURAK) — have published a paper that explores the viability of the use of rice husk ash as a partial replacement of cement for the production of sustainable concrete.

Rice husk ash (RHA), which is rich in silica, has favorable chemistry as supplementary cement-like material for use in concrete. The use of RHA in concrete results in its chemical reaction with the hydrates of cement, chiefly Calcium Hydroxide, and forms secondary products that impart strength and stability to the resulting concrete mixture.
