Experimental Investigation on High-Performance Light-Weight Concrete Using Cotton Fine Trash as Partial Cement Replacement

Abstract

The use of cotton fine trash, a byproduct of the cotton industry, as a partial substitute for  cement in high-performance concrete is examined in this study. The key objective is to assess how various replacement levels (0%, 5%, 10%, 20%, and 30%) influence concrete's workability, density, tensile strength, flexural strength, and compressive strength. The 10% level of replacement (M2) provided the best property balance among the evaluated mixes. The 10% mix showed greater workability, as seen by higher slump, compaction factor, and flow table values as well as a shorter Vee-Bee time. This was explained by better particle packing and less friction because the cotton fine trash was fibrous. Along with higher flexural and tensile strengths, the 10% replacement level also showed the strongest compressive strength at 7, 14, and 28 days. These advantages are attributed to greater particle packing, possible pozzolanic reactions, and enhanced bonding characteristics of the cotton fine trash. Furthermore, the concrete's density dropped as the amount of cotton fine trash increased, which makes the 10% mix advantageous for lightweight concrete applications. Higher negative mechanical qualities, and the concrete cement content, and the negative organic material content of the negative organic material. By encouraging the recycling of industrial waste and lowering reliance on conventional cement, the study emphasizes the sustainability advantages of employing cotton fine rubbish in concrete.
