Influence of processed spent bleaching earth on the durability of foamed concrete in acidic environment

The present research investigates the durability performance of foamed concrete with PSBE as partial cement replacement upon exposure to acidic environment. A basic control mix of foamed concrete (FC) cube was designed for density of 1600kg/m3 and 30% of PSBE by weight of cement namely as PFC were...
