Experimental Investigation On Self Healing Concrete With Calcium Lactate And Pseudomonas Fluorescens Bacteria

Abstract

Bacterial concrete has lately appeared as a new option for healing cracks in constructions such as pavements, reinforcedconcrete (RCC) buildings, bridges, pipes, and canal linings. Commonly occurring cracks in concrete allow chemicals andwater to seep in, weakening the structure and harming the reinforcement when exposed to these and other pollutants. Itmight be expensive to repair these cracks because they usually need regular upkeep and specialist treatments. Henk Jonkersdeveloped bacterial concrete as a solution to this problem, allowing concrete structures to have their fissuresrepaired.According to his research, some bacteria can be employed to seal existing fissures. The usage of calcium lactateand the bacteria Pseudomonas fluorescens to stop concrete cracking is investigated in this experimental investigation.Thekey to the bacteria's selection is its capacity to endure in an alkaline environment. Pseudomonas fluorescens and calciumlactate were added to M40 grade concrete in the investigation at weight percentages of 5%, 10%, and 15%. A link betweencompressive strength and flexural strength is given as the empirical formula.
