Performance of agro-waste sugarcane bagasse ash in concrete under durability tests

The concrete industry frequently uses waste material known as sugarcane bagasse ash (SCBA) because of its excellent pozzolanic qualities. Cement is a rare and essential component of concrete construction that is in high demand all over the world. Meanwhile, carbon dioxide (CO2) is generated widely due to the infrastructure development in the construction sector. To lower CO2 emissions, concrete must contain less cement. Replacing some of the cement in concrete with agricultural wastes such as rice husks and sugar cane bagasse significantly reduces the material’s environmental impact. Therefore, this study focuses on the durability performance of concrete with sugarcane bagasse ash as a partial replacement for cement at 5%, 10% and 15% by weight. The durability of the concrete was studied through the electrical resistivity test, rapid chloride infiltration test, initial surface absorption test, as well as carbonation after 7 days and 28 days. It was observed that the SCBA is a pozzolanic substance with good binder qualities that may be utilised in concrete mixtures to partially replace costly cement.
