Abstract

As cotton dust (CD) from spinning textile industry contains considerable amounts of cellulose, it can be used as an
alternative secondary material for the production of concrete. This study was performed by replacing cementitious material
with incinerated CD. Fresh and hardened cotton dust ash concrete was compared to a reference series. The level of replacement was at 0%, 5%, 10%, 15%, and 20% by weight. Observed results indicated that CD ash concrete had consistently led to
improvement in strength performance. It was found that CD ash dosage at 10% by weight gave the ultimate compressive,
flexural, and splitting tensile strength of 32.92, 8.36, and 4.84 N/mm²
, respectively. However, an increase in the percentage
replacement of CD ash dosage resulted in an increase in the porosity of concrete. The results evidently exhibited that CD ash
can be used for partial replacement of cement in concrete. Thus, the partial substitution of CD ash helps to contribute
towards sustainable development in civil engineering practices
