Experimental investigation on mechanical, durability, and microstructural sugarcane bagasse fiber reinforced concrete with partial replacement of cement by corn waste ash
Abstract The expensive cost of cement and environmental pollution resulted in its production can be decreased by using partially cement replacing materials like corn waste ash (CWA).

| description | Abstract The expensive cost of cement and environmental pollution resulted in its production can be decreased by using partially cement replacing materials like corn waste ash (CWA). CWA (a blend of Corncob ash and Cornhusks ash) have been found to contribute to the better improvement of concrete properties such as high strength, durability, thermal conductivity and insulating properties. In addition, concrete cracks and issues of strength can solved using fibrous materials. Sugarcane bagasse fiber (SCBF) also has a great effect on microstructure of concrete mix since it allows a homogeneous distribution of the cement paste. In this study, the effect of CWA and SCBF on concrete strength, durability and microstructure was investigated. Concrete composite with 1% SCBF gains strength within the acceptable strength limit, which is required to attain 65% of the strength gained at 28 days. An optimum of 1% SCBF was used to reinforce concrete. The split tensile strength of SCBF reinforced concrete increased with CWA blend increment up to CWA of 7.5% cement replacement, then it decreased. The compressive strength of SCBF reinforced concrete decreased with CWA blend increment. The least water absorption and the highest resistance to chemical attack (H2SO4 and NaOH) of SCBF-reinforced concrete were observed with a CWA of 7.5% blend. However, for further addition of CWA, water absorption and weight loss due to chemical attack increases. After 28 days of % sulfuric acid curing, the optimum compressive strength was found with a CWA of 2.5% blend. The microstructure of SCBF reinforced with CWA of 2.5% blend shows very compacted with negligible pores and cracks due to the filler effect of CWA and its pozzolanic reaction. |
