Types of Admixtures used in Concrete Construction Chemical

Concrete admixtures' construction chemicals are the ingredients other than water, portland cement, and aggregates that are used to modify the properties such as heat of hydration, accelerate or retard setting time, workability, water reduction, and dispersion and air-entrainment, impermeability, and durability factors. Concrete admixtures are available as mineral and chemical admixtures.

Chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing. Producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete during mixing, transporting, placing, and curing; and to overcome certain emergencies during concrete operations.

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.

Types of Concrete Admixtures

Concrete admixtures are of different types and they are as follows:
  1. Water Reducing Admixtures
  2. Retarding Admixtures
  3. Accelerating Admixtures
  4. Air entraining concrete admixture
  5. Pozzolanic Admixtures
  6. Damp-proofing Admixtures
  7. Gas forming Admixtures
  8. Air detraining Admixtures

Wood Pellet Market Set for Massive Progress in the Nearby Future

  Wood pellets are produced using finely ground wood bark and majorly used as a fuel. These are extensively used in residential houses for efficient burning in smaller stoves. Wood pellets are produced from numerous wood waste products and considered as a source of renewable energy. Currently, along with residential heating, there is an increased use of wood pellets market for power generation across the globe. These are largely utilized globally as fuel which is also expected to increase the demand for wood pellet in coming years. Europe is the leading region for the consumption of wood pallets for power generation, along with this North America is the significant exporter and expected to increase the production facilities of wood pellet in coming years. Renewable energy plays a vital role to play in meeting the future energy needs in both rural and urban areas. The scarcity of resources, along with an increase in awareness about adverse environmental impacts of fossil-based pr...
