Super Absorbent Polymer. A pH responsive super absorbent polymer used in chemical method. Water-absorbing polymers, which are classified  Sep 10, 2015 · Chemical Admixtures for Concrete. Chemical admixtures can either accelerate or slow the curing process, reduce the water content, or introduce air bubbles into the mix—called air-entraining admixtures. Each type of admixture is introduced to the concrete during the batching process, targeting a specific concrete challenge:
  • Types of Admixture. There are mainly two types of admixtures . Mineral admixtures; Chemical admixtures; Mineral Admixture. Mineral admixtures are siliceous and insoluble material other than cement and aggregate that are added at a range of 20 to 70 percentage by the mass of cement.These are fine materials that affect the concrete by hydraulic and pozzolanic activity.
  • Oct 15, 2021 · Admixture types | Mineral and Chemical Admixture Admixture is an ingredient added in concrete along with cement, sand, water, and aggregates to modify/enhance the properties of concrete and make it more desirable for a particular environment.
  • Pozzolanic or Mineral admixtures; There are various types of chemical admixtures that we have already discussed in our previous articles such as concrete accelerators, concrete retarders, plasticizers, superplasticizers, air entraining admixtures etc. Here we will discuss pozzolanic or mineral admixtures.
  • Among many types of chemical admixtures, air-entraining admixtures and water-reducing admixtures (WRAs) are commonly used in modern concrete. Air-entraining admixtures encourage microscopic air bubbles (10-1000 µm in diameter) to form and stabilize these bubbles during the mixing of the fresh concrete.
  • Bonding admixtures can be divided into the two groups as follows: 1. Re emulsifiable type . 2. Non re-emulsifiable type. This class of bonding admixtures is better suited for external use as it is water resistant. These emulsions generally are added to the mixtures in proportion of 5 to 20% by weight of cement.
  • Among many types of chemical admixtures, air-entraining admixtures and water-reducing admixtures (WRAs) are commonly used in modern concrete. Air-entraining admixtures encourage microscopic air bubbles (10-1000 µm in diameter) to form and stabilize these bubbles during the mixing of the fresh concrete.
  • Gas forming Admixture: A gas-forming agent is a chemical admixture which reacts with the hydroxide produced in the hydration process to produce minute bubbles of hydrogen gas throughout the cement matrix. It causes a slight expansion of plastic concrete and increases the bond between the rebars and the grout.
