Sulfur concrete is usually a Particular concrete that takes advantage of sulfur as being a binder and won't require cement or drinking water.
Yet another method of mass concrete structures that minimizes cement's thermal by-products is the use of roller-compacted concrete, which takes advantage of a dry combine that has a A lot decreased cooling requirement than typical soaked placement.
This phenomenon of prestressing can make the decrease part of your concrete member to be stronger towards the tension. The process of prestressing will require hefty tools and labor skill (jacks and gear for tensioning). That's why the prestressing units are made at website and assembled at website. These are generally Utilized in the application of bridges, hefty loaded structures, and roof with longer spans. Also Read: Prestressed Concrete Concepts, Will need and Strengths 5. Precast Concrete
