Today researchers all over the world are focusing on ways of utilizing either industrial or agricultural wastes as a source ofraw materials for the construction industry. The sugarcane bagasse is locally utilized in sugar industries for power production that yields a huge amount of dumped waste sugarcane bagasse ash. This waste utilization would not only be economical but may also help to create a sustainable and pollution-free environment. As river sand resources are depleting worldwide due to uncontrolled extraction of sand for concrete production. Sugarcane bagasse is one such fibrous waste- product of the sugar refining industry, along with ethanol vapor. Bagasse ash mainly contains aluminium ions and silica. This study presents the laboratory work on lightweight foamed concrete made by partial replacement of fine aggregate with sugarcane bagasse ash by using the synthetic foaming agent. The untreated bagasse ash has been partially replaced in the ratio of 5%, 10%, and 15% by volume of fine aggregate in concrete. The study intends to ascertain the compressive strength of foam concrete with sugarcane bagasse ash in different percentages as above mentioned. Mix design of M30 is performed for foam concrete and the compressive strength was tested for 7 days, 14 days and 28 days for cube specimens and split tensile strength for cylinders. And the same is compared with varying the percentages of SCBA. The result shows that bagasse ash can be a suitable replacement for fine aggregate.
