Hydrated Lime Applications : 

  • Hydrated lime or quicklime is mixed with water to give an alkaline slurry which neutralises the low pH of acids. Milk of lime can also be used to avoid the need for slurrying equipment. Often insoluble calcium salt is precipitated during the reaction which can help to remove impurities from the system. It is mainly used in waste water treatment.
  • Quicklime is mixed with cement, sand, water and aluminium powder to give a slurry which rises and sets to form honeycomb structured blocks which have excellent thermal and sound insulation properties. The heat generated when quicklime reacts with water and the alkaline conditions combined with aluminium powder generates hydrogen bubbles which cause the blocks to rise.

    The heat generated subsequently causes the slurry to set. The blocks are then heated in an autoclave, which promotes reactions between calcium and silicates in the sand or PFA and gives extra strength. Dolomite lime and/or modified quicklime can be added to reduce excessive shrinkage or cracking.

  • Hydrated Lime or Slaked Lime is also used in Paper and Plastics / Rubber Industry. The caustic properties of hydrated lime are used in the sulphate process during the manufacture of paper and pulp. When making plastic, if any potential water is not removed then steam bubbles may occur in the finished product, which can affect its strength and appearance.
