Abstract

Across world cement is utilized as one of the chief raw materials in construction sector. Increased production of cement to meet the demands from construction sector has resulted in emission of catastrophic amount of CO2 gas into the atmosphere. Awareness about global warming has resulted in innovation of inorganic polymer binder termed as Geopolymer concrete (GPC). In recent times, priority is given to studies focusing on development of self-consolidating ability in GPC. Such concrete is being addressed by the term Self-consolidating Geopolymer Concrete (SCGC). This experimental investigation focuses on studying the influence of Bacillus Subtilis bacteria on workability and strength characteristics of alkali activated Self-consolidating concrete (SCC) mixes. Experimental studies were carried out on 10 different SCGC mixes. In each mix, bacterial cell concentration was varied in order of 0%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8% and 9% of total binder content. Test values concluded that all fresh SCGC mixes with bacteria exhibited better workability as per EFNARC guidelines.
