The durability of a structure depends on the strength of concrete as well as the ability of the cement to deflect in case there is a load applied to it. This is done by looking at the tensile strength and elastic modulus. Load-bearing capacity is done using deflection which is measured by compressive strength of the cubes and cylinders in the experiment.
In the construction industry, bagasse has been used as a substitute for Portland cement (Thangavel, 2007). This is because it has a high silica content which is the same as Portland cement. On the other hand, it is considered to be less costly and can easily be obtained as opposed to Portland cement. Bagasse ash is manufactured by burning the bagasse.
