The bacterial concrete is one step forward towards smart concrete. The smart concrete was to be defined as concrete adopt itself as around its environment.
Soil bacterium commonly called Bacillus Pasteruii was used in bacterial concrete. Over the mortar layer it create the layer of calcite which is highly impermeable.
The bacterial concrete has the ability to repair itself (Bio-Material) also called smart Bio-Material. The plastic shrinkage cracks were sufficiently improved by using this concrete. The smart concrete increase the durability of concrete (Higher the bacterial dosage, Higher the performance).
- Alkali and sulphate attack resistance was sufficiently improved.
- Freezing and thawing resistance was improved.
- Plastic shrinkage cracks where reduced.
- The strength was increased 5% to 10% as compared to ordinary concrete.
