Special concrete is concrete whose one or more characteristics are more important depending on the conditions or situation of the project. These special functions and characteristics achieve by taking advantage of fundamental improvements in the application of raw materials or new technologies. In some cases, special aggregates, light aggregates, steel fibers, plastic fibers, glass fibers, special heavy aggregates or special additives are necessary.
In fact, special concrete is a particular mix design to achieve the desired technical specifications in concrete. In order to achieve high compressive and tensile strength, being waterproof, and improving chemical resistance, the use of polymers and special additives is unavoidable.
