High Performance Slab Gap Filler - Fly Ash For Cement Raw Materials Coal Fly Ash For Concrete Admixtures – Kehui

Fly ash is a fine powder that is a byproduct of burning pulverized coal in electric generation power plants. Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement. This makes fly ash suitable as a prime material in blended cement, mosaic tiles, and hollow blocks, among other building materials. When used in concrete mixes, fly ash improves the strength and segregation of the concrete and makes it easier to pump.

Fly ash can be used as prime material in many cement-based products, such as poured concrete, concrete block, and brick.
Adding fly ash to the concrete saves a lot of cement and fine aggregate, reduces water consumption; improves the workability of the concrete mixture; enhances the pumpability of concrete; reduces the creep of concrete; Heat of hydration and thermal expansion; improve the impermeability of concrete; increase the modification of concrete.

We also can offer Class C Fly Ash,it provides unique self-hardening characteristics and reduces permeability. Especially useful in pre-stressed concrete and other applications where high early strengths are required. Also useful in soil stabilization.
