“…Among the samples tested, those containing calcium lactate and bacteria exhibited the highest compressive strength, demonstrating a significant enhancement of 17%. Additionally, a thorough analysis of flexural strength recovery was conducted on the concrete samples, exhibiting that the control specimen displayed better flexural strength recovery (41.5%) compared to the variant containing bacteria (26.1%) after subjecting them to 28 days of wet/dry cycles [19].…”

Background: Due to advances in biotechnology and the material sciences in the last decade, we have developed some smart and innovative materials that can be developed further to benefit humanity. One of them is the self-healing concrete which could be hyper-porous - holding water like a sponge and which can be used for making our building eco-friendly by using the green walls and green roofs concept. This self-healing concrete composed of 90% recycled material. On the other hand, there is self-sensing concrete (pressure-sensitive or piezoresistive concrete) which has been developed by mixing functional fillers like-carbon fibres, carbon nanotubes, nickel powder, steel fibres, etc. into concrete to enhance its capacity to sense stress, strain, cracking or damage and even improving mechanical properties which can be used further for converting the footfalls into electricity and developing self-sensing building to act as a warning system for the residents in event of any natural or man-made calamities. Methods: We have used the systematic literature study to find the latest developments in the field of material science regarding these two materials under discussion. This will focus more on the recent research and wider applications by encouraging more research and adaptation. Findings: This research paper will delve into depth to find more interesting aspects of the new innovative materials and study the comparatively different aspects like applicability, uses, manufacturing process, cost of construction, time of setting, environmental benefits and economic benefits that humanity can gain by adopting this in construction of buildings. Results: This research will help policymakers to look for more comprehensive uses in future. Conclusions: The findings of the research paper will help in the adoption and further research in the field of biocrete and self-sensing concrete which can be applied in the field of construction and other allied fields for the future.
