Also Read:High Performance Admixtures. Concrete additives have various functions depending on what the contractor wants to achieve. There are two main types of concrete additives which are chemical and mineral.
In high performance concrete, this is the method of choice, since it increases the cementitious content. This increase is compensated by a decrease in the fine aggregate content. Addition method usually results in higher strengths.when fine materials such as silica fume are used, this method can cause a substantial increase in the water demand.
Mineral additives zeolites, SiO 2 micro dust etc. are some of the most prospective components of concrete in the development of new building materials such as high performance concretes, special concretes absorbing heavy metals or suppressing radioactive radiation. These additives modify and accelerate Portland cement hydration process ...

studied at the end of the last century. Currently, high-performance concrete is used in massive volumes due to its technical and economic advantages. Such materials are characterized by improved mechanical and durability properties resulting from the use of chemical and mineral admixtures as well as specialized production processes. This paper
The additives can be added at the manufacturing point, or at the job site. At Big D Ready Mix, we ensure we follow the best concreting and batch methods. There are two types of additives, chemical and mineral additives. Their usage depends on what the contractor wants to achieve. Chemical Additives. These are used to: Reduce the construction cost
Ultra-High Performance Concrete UHPC is a relatively new construction material, which is a combination of high performance concrete, minerals admixture and steel fibers. The compressive strength reaches beyond 150 MPa, which allows the construction of sustainable and economic buildings with an extraordinarily slim design.
