Abstract
This experimental study is deals with assessment of behavior of bacterial concrete with three different bacteria’s such as Bacillus Subtilis, Bacillus Sereus and E- Coli. M25 grade concrete mix is designed as per IS 10262: 2009. The compressive strength is carried out at 7, 14 and 28 days of curing period, whereas the water permeability test is done at 28 days to determine co-efficient of permeability of concrete. The 7 Days compressive strength results shows that the Bacillus Subtilis, Bacillus Sereus and E- Coli strength increases by 13.07% , 11.11% and 14.36 % respectively as that of normal concrete. The 28 Days compressive strength results show that the Bacillus Subtilis, and E- Coli strength increases by 6.20% and 13.88% respectively. Bacillus Sereus strength decreases by 6.95 % comparing with normal concrete. The co efficient of permeability for Bacillus Subtilis, Bacillus Sereus and E- Coli bacteria decreased by 63.76 %, 51.18 % and 92.90 % as that of normal concrete.
