Bioconcrete Technology and Neglected Biotoxicity

Abstract

Bioremediation of concrete durability issues becomes a new trend to revise and adopt. Bacteriology becomes an important branch of science in concrete applications. The use of nonpathogenic bacteria spores as microorganisms for biodeposition of calcite in concrete has been widely investigated. These microorganisms play same role as a self-healing agent, which has attracted the attention of several researchers while neglecting the biotoxicity side. Moreover, fewer have pointed at the provisions and precautions that should be applied to avoid “opportunistic pathogenic attacks” on living organisms within the boundaries of microbial concrete structures. The presence of bacteriologist is highly crucial for safe application of bioremediation of concrete properties. Limited applications are suggested. Introduction
