Experimental investigation of Bamboo Leaf Ash and Rice Husk Ash as partial replacement cement in concrete

Abstract

Construction work was mostly done in the ancient era using mudstone obtained from industry. The experimental investigation on the strength properties of M30 grade concrete, in which rice husk ash and bamboo leaf ash have largely substituted cement. One of these waste materials produced as a by-product of the rice paddy milling industry is rice husk ash (RHA). and Bamboo is used as scaffolding for the manufacture of domestic goods and construction paper. In this investigation, concrete specimens created with 0%, 5%, 10%, and 15% of the RHAsh and BLAsh as the cement replacement percentages were used to calculate the strength-related parameters such as compressive strength, splitting tensile strength, and flexural strength. Samples were examined at 7, 14, and 28 days old. Finally, it was determined that, when compared to other replacement levels, the 5% RHAsh and BLAsh replacement level in M30 grade concrete demonstrated to be greater.
