How long can bacteria survive in dry concrete?

These spores are viable but dormant cells and can withstand mechanical and chemical stresses and remain in dry state viable for periods over 50 years (Fig. 1). However, when bacterial spores were directly added to the concrete mixture, their life- time appeared to be limited to one-two months [16].

How does bacteria improve the strength of concrete?

The bacterial Bacillus pasteruil in the concentration of 8.6*108 cells/ml can improve the strength of the concrete by forming a calcite layer in the crack. Thus, the strength of the beams has improved back to 81.97% of the original strength.

What happens to calcium lactate in bacterial concrete?

As the bacteria feeds oxygen is consumed and th e soluble calcium lactate is converted to insoluble limestone. The limestone solidifies on the cracked surface, t hereby sealing it up [6]. As the oxygen is consumed by bacteria in the process, it prevents corrosion of the embedded form of leaching.

How is bacterial concrete used for crack remediation?

BACTERIAL CONCRETE (Microbiologically Enhanced Crack Remediation Technique) INTRODUCTION Cracking is an inevitable phenomenon in structures and is one of the inherent weaknesses. Water and other salts seep through these cracks; corrosion initiates, and thus reduces the life of structures.
