Abstract

In Malaysia and worldwidely, concrete is one of the most popular construction material because of it's strong, durable and inexpensive material. It has speciality of being cast in any desirable shape but plain concrete however is porous, possesses very low tensile strength, limited ductility and little resistance to cracking. These problem become more complicated in various environmental condition like Malaysia to which concrete is exposed. Conventionally, a variety of sealing agent namely, latex emulsions suffer from serious limitations of incompatible interfaces, susceptible to ultraviolet radiations, unstable molecular structure and high cost. Therefore, a novel and more environmental friendly technique is proposed for treating concrete material in structure by employing bacteria induced calcium carbonate precipitation in the form of calcite
