Study of microstructural analysis (MSA) on properties related to strength and its characteristics on bacterial concrete

Abstract

Cement Concrete broadly used in building material for all civil engineering applications due to its well-known In India Conventional Cement Concrete (CCC) are used in growth of construction. Concrete is liable to create a micro crack while substituting by building materials and consumes pores which are highly unwanted because of were they afford an open pathway for water and other poisonous substances. In way to improve more durable for the structure it is better to take HPC. It is also a cement concrete which has far bigger strength and durability features compared to CCC. HPC does not mean only achieving the detailed compressive strength but also other parameters such as im-permeability, resistance to environmental factors, shrinkage, corrosion resistance, electrical resistivity etc. In this study the mineral admixtures are to add. such they are silica fume, ground granulated blast furnace slag, rice husk ash, fly ash and highly reactive metakaolin in and also have a look on improvement in the micro-structure of concrete in various complexes. The bacterial degradation technique is eco-friendly and durable. Bacteria need to resist withstand high pH of concrete and mechanical stresses during mixing. Based on the data collection of literature that, information available that different bacterial samples namely Bacillus Megaterium (BM), Bacillus Subtilis (BS) and Pseudomonas Aeruginosa (PA) are considered in concentrations of 104, 105 and 106 cells/ml of mixing of water. M30 grade concrete is designed and used for embedding different types of bacteria. In this dissertation, investigations are carried out on strength-related possessions such as compressive strength, splitting tensile strength, flexural strength, modulus of elasticity and bond strength.
