Scientists Have Ascertained A Method To Create Environment-Friendly Cement From Waste Materials,
Scientists at Nanyang Technological University In Singapore(NTU Singapore) have ascertained a method to create bio-cement from waste materials, converting it into a viridescent and more imperishable replacement for ordinary cement. Bio-Cement is a kind of inexhaustible cement that combines soil into soil block by the use of bacteria to persuade a hardening reaction. Bio-Cement is being prepared by NTU scientists using two ordinary waste products - Industrial carbide sludge and urea ( (from mammalian urine). They discovered a process for making hard solid or precipitate in industrial carbide sludge by mixing urea with calcium ions.

- Bio-Cement creation is more environment-friendly than the standard cement
The precipitate ties soil particles with each other and infuses gaps between them when this reaction takes place in the soil, deriving in a dense mass of soil. This develops a bio-cement block that is herculean, long-standing, and impregnable to water.
The study was divulged in the Journal of Environmental Chemical Engineering. The analysts surmise that their bio-cement might work to enhance the soil in a wide range of ways, involving hardening the ground for construction and excavation, limiting beach erosion, reducing dust or wind erosion in the desert, and constructing freshwater reservoirs on the beaches or in the desert.
It can also be utilized as bio grout to seal cracks in rocks for oozing control and also for renovation and repair of monuments like rock carvings and statues.
Professor Chu Jian, Chair of the School of Civil and Environmental Engineering and who is also the Director of NTU's Centre for Urban Solutions, said that bio cement was imperishable and inexhaustible alternative to traditional cement that has a lot of capability in construction projects. In the long run, it will not only reduce the cost of manufacturing bio-cement, but also the cost of waste disposal.
Bio-Cement creation is more environment-friendly than the standard cement manufacturing processes. Professor Chu said that the burning of raw materials at a very high temperature exceeding 1,000 degrees Celcius generates clinkers which is a cement tieing agent is one aspect of the cement forming process. This process emits a noteworthy amount of carbon dioxide. Bio-Cement on the other hand is prepared at room temperature without using any energy.
