  • What are anti-washout admixtures?
  • Anti-washout admixtures are used in concrete especially for under water concrete structure. It protect the concrete mix from being washed out under water pressure. It improves the cohesiveness of concrete. This type of admixtures are prepared from natural or synthetic rubbers, cellulose based thickeners etc. 11. Grouting Admixtures
  • What are accelerator admixtures?
  • Accelerating admixtures are used to reduce the initial setting time of concrete. They speed up the process of initial stage of hardening of concrete hence they are also called as accelerators. These accelerators also improves the strength of concrete in it early stage by increasing the rate of hydration.
  • What are the different types of admixtures used in concrete?
  • Various types of admixtures are used in concrete to enhance the performance of concrete. Concrete admixture is defined as the material other than the aggregate, water and cement added to the concrete. 1. Water Reducing Admixtures Water reducing admixtures, the name itself defining that they are used to minimize the water demand in a concrete mix.
  • What is superplasticizing concrete admixture used for?
  • Our products are good for ready mix concrete used for swimming pools, sea walls, tunnels, bridges, basement, etc. Our superplasticizing concrete admixture products are used in hot climates like Nigeria to produce Precast and ready mix concrete, slabs, basements, foundations, walls, columns and piers.
  • What are water reducing admixtures?
  • In addition to increase in workability it also improves the strength of concrete, good bond between concrete and steel, prevents cracking, segregation, honeycombing, bleeding etc. Water reducing admixtures are also called as plasticizers and these are classified into three types namely plasticizers, mid-range plasticizers and super plasticizers.
  • What are pozzolanic admixtures used for?
  • Pozzolanic admixtures are used to prepare dense concrete mix which is bets suitable for water retaining structures like dams, reservoirs etc. They also reduce the heat of hydration and thermal shrinkage.
