        abstract = {Concrete is widely used in civil engineering infrastructure, but cracking is one of its major durability problems. Cracks may permit the entry of water and aggressive agents and can increase maintenance requirements. Self-healing concrete is an innovative material designed to seal or repair cracks without conventional manual intervention. This paper presents a preliminary study and development of bacterial self-healing concrete using bacteria and calcium lactate as the healing system. The work is based on a diploma project in which cement, fine aggregate, coarse aggregate, water, bacteria and calcium lactate were used. The experimental procedure involved preparation of the bacterial solution, concrete mixing, specimen casting, curing, controlled crack formation and observation of crack healing. The source project reports that the induced cracks were reduced after the healing period and that durability was improved compared with conventional concrete. The study discusses the mechanism, materials, methodology, advantages, limitations, applications, cost and future scope of bacterial self-healing concrete. Since the source project does not provide numerical crack-width, healing-percentage, strength or statistical data, the results are reported qualitatively rather than by invented numerical values. The study indicates that bacterial self-healing concrete has promising potential for durable and sustainable construction, while further controlled experimental testing is required for quantitative validation.},
