It is a mixture of Portland cement, water and aggregates: sand, gravel, or crushed stone. Batch plants combine a precise amount of rock, sand, water and cement together by weight, allowing specialty concrete mixtures to be developed and implemented on construction sites.
Fly ash is a fine powder which is a by product from burning pulverized coal in electric generation power plants. The fly ash produced by coal-fired power plants provide an excellent prime material used in blended cement, mosaic tiles, and hollow blocks among others.
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. Successful use of admixtures depends on the use of appropriate methods of batching and concreting. Most admixtures are supplied in ready-to-use liquid form and are added to the concrete at the plant or at the jobsite.
Coarse aggregates are an important material used in the production of concrete products, which provides strength to concrete. They are also known as Jelly/stones, Blue Metal or Crushed Stones. Coarse aggregates are particles greater than 4.75mm, but generally range between 9.5mm to 37.5mm in diameter. They can either be from Primary, Secondary or Recycled sources.
This cement is commonly used for House construction RCC works, where initial setting time is not of importance. PPC cement is a blended portland pozzolana cement, which is best suited for non -building concreting works like brick/ block walls construction, flooring, plastering as chances of developing cracks are less due to low heat of hydration.
Light weight concrete which is lighter than conventional concrete. It has thermal properties and sound insulation. It reduces loads on foundation and sunken slab. Easily pumpable it permits modification on the structural member with minimal dead load.
Screed is a thin, top layer of material laid over a concrete subfloor, that is traditionally made of sharp sand and cement. It is used to cover structural flooring concrete, and can be applied to either a solid, in-situ or precast concrete floor slab. It shows durability under various service conditions. It creates a smooth, level surface finish. It reduces surface cracks.
