Flexural Behavior of RC Beams by Using Agricultural Waste as a Cement Reinforcement Materials

Taha A. El-Sayed, Abeer M. Erfan & Ragab M. Abd El-Naby · Journal of Engineering Research and Reports · 2019

Using replacement for cement to assure sustainability is critical as the raw materials (limestone, sand, shale, clay and iron ore) used in making cement are depleting. The use of agriculture waste byproducts to replace cement is becoming an economic option. Rice husk ash (RHA), r...
