Abstract
Concrete structure are subjected to cracks and it is one of the immanent frailties of concrete thus reduces the life of concrete structure thereby results in high replacement cost. The study was inspired by the technique to find a remedy for cracking using bacteria namely Bacillus subtilis and Bacillus cereus on filling the voids, and the compressive strength, split tensile strength and flexural strength of bacterial impregnated concrete are compared with conventional concrete. The evaluated results of strength revealed that the use of bacteria in combination showed better improvement and SEM, XRD analysis showed that the material growth, increased calcite crystalline when compared to conventional concrete.
混凝土结构会出现裂缝，这是混凝土的一个固有缺陷，因此会降低混凝土结构的寿命，从而导致高昂的更换费用。这项研究的灵感来自于利用细菌（枯草芽孢杆菌和蜡样芽孢杆菌）填充空隙的开裂补救技术，并将细菌浸渍混凝土的抗压强度、劈裂拉伸强度和抗折强度与传统混凝土进行了比较。强度评估结果表明，结合使用细菌能更好地提高强度，扫描电镜和 X 射线衍射分析表明，与传统混凝土相比，材料增长，方解石结晶增加。
