Abstract
The aim of this study was to investigate the influence of bacterial carbonate precipitation on the compressive strength and capillary water uptake of fly ash concrete. Cement was replaced with three percentages (10%, 20% and 30%) with fly ash by weight. The effects of bacterial induced precipitation on concrete strength were studied through compressive strength test. Tests were carried out for compressive strength and water absorption at the age of 28 days. Experimental results indicated that Acinetobacterjohnsonii induced carbonate precipitation in fly ash concrete enhanced the compressive strength. Bacterial carbonate precipitation effectively reduces capillary water uptake, and reduced the porosity of fly ash concrete. Acinetobacterjohnsonii induced carbonate precipitation improves strength and durability of fly ash concrete.
