TI  - Bio-Cementation in Construction Materials: A Review.

AB  - The rapid development of the construction sector has led to massive use of raw 
      construction materials, which are at risk of exhaustion. The problem is 
      aggravated by the high demand for cement as binding powder and the mass 
      production of clay bricks for construction purposes. This scenario has led to 
      high energy consumption and carbon emissions in their production. In this regard, 
      bio-cementation is considered a green solution to building construction, because 
      this technology is environmentally friendly and capable of reducing carbon 
      emissions, thus slowing the global warming rate. Most of the previously published 
      articles have focused on microbiologically induced calcium carbonate 
      precipitation (MICP), with the mechanism of bio-cementation related to the 
      occurrence of urea hydrolysis as a result of the urease enzymatic activity by the 
      microbes that yielded ammonium and carbonate ions. These ions would then react 
      with calcium ions under favorable conditions to precipitate calcium carbonate. 
      MICP was investigated for crack repair and the surface treatment of various types 
      of construction materials. Research on MICP for the production of binders in 
      construction materials has become a recent trend in construction engineering. 
      With the development of cutting edge MICP research, it is beneficial for this 
      article to review the recent trend of MICP in construction engineering, so that a 
      comprehensive understanding on microbial utilization for bio-cementation can be 
      achieved.
