High Performance Concrete Additives. Modified date: Aug 14, 2021. Concrete additives are added to the mixture of water cement and aggregate in small quantities to increase the durability of the concrete, to fix concrete behavior and to control setting or hardening. They can either be liquid or powdered additives.

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.

In this study, the change of the effect of high temperature in concrete by the types of mineral additives was examined experimentally. For this purpose, CEM I 42,5 R cement was used together with different minerals such as Barite, Diatomite, Silica fume, F class Fly ash that are added in a substituted manner at the rates of 10%, 20%, 30% and 40% by volume.

Therefore, high performance concrete (HPC) is used massively due to its technical and economical advantages to fulfil people demands towards the concrete usage. Optimum mineral blended admixture replacement ratio with the addition of superplasticizer are the main component which contributed to the formation of HPC in terms of high workability, high strength and high durability.

With mineral additives added to the concrete mix the strength of concrete with the same or higher w/c ratio increases . 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.
