Experimental investigation of fiber reinforced concrete using septage ash

Abstract

In this experimental investigation, the concrete has replaced with septage ash in place of cement and banana fiber is added as a percentage of the weight of cement. Concrete is one of the materials which use a maximum number of non-renewable resources. Due to the high demand for non-renewable resources in the construction industry, recent investigations are carried out to find alternative construction materials which are eco-friendly and cause some impact in reducing pollution in the environment. Septage ash or septic tank sludge is the by-product from the faucal sludge sewage treatment plant of household septic tanks. Banana fiber is the natural fiber which is obtained from the stem of the banana tree, banana fiber is mainly used in the textile industry, but a huge quantity of fiber which can’t be used in the textile manufacturing is as waste. So, in this experimental investigation authors have used these two materials to find the optimum percentage that can be replaced in concrete. In this research septage ash is put back by 10%, 20%, 30%, and 40% instead of cement without and with banana fiber added 1% of the weight of cement. Compressive, tensile along with flexural strength test is conducted for 7days and 28 days and results are compared to finding the optimum percentage of septage ash with banana fiber that can be replaced instead of cement.
