Performance Evaluation of Strength and Durability of Cement Mortar with Ceramic waste Powder and Bacterial Solution

Abstract

This paper reports the experimental investigation of partial substitution of cement with ceramic waste powder and water-cement ratio with bacterial solution. The entire investigation was carried out in two phases. In 1^st phase, cement was substituted with ceramic waste powder and in the 2^nd phase, along with the cement, 50% of water-cement ratio was also substituted with the bacterial solution. The water-binder ratio was kept constant at 0.32 throughout the investigation. The compressive strength, UPV and pH values of the samples were investigated after 3, 7, 28 and 56 days of curing. The 1^st phase results showed a decline in the compressive strength as well as in the UPV values. At 10% substitution the decline was not very much significant but reached to around 40% at 50 percent substitution. In the 2^ndphase, 10% and 20 % cement substitution with ceramic waste powder has shown significant improvement in the compressive strength as well as in UPV values. At 10 % substitution, the increase in strength was around 45% for both 7 and 28 days of curing. The pH value of the samples in the second phase at 3, 7, 28 and 56 days of curing was between 11.30 – 12.52.
