Fly ash is an inexpensive replacement for portland cement used in concrete, while it actually improves strength, segregation, and ease of pumping of the concrete. Fly ash is also used as an ingredient in brick, block, paving, and structural fills. Fly ash can be a cost effective partial substitute for Portland cement in markets that are experiencing supply shortages.
An industrial by-product that is otherwise waste, fly ash is environmentally friendly because it is recycled and has low embodied energy.
Because fly ash cement requires less water than portland cement, it is easier to use in cold weather. It can be formulated to produce various set times, cold weather resistances, strengths and strength gains, depending on the job. Fly ash can be used sparingly as an admixture or in large amounts to replace portland cement. The material is somewhat lighter than portland cement.

Diatomaceous earth (DE), also known as diatomite, diahydro, kieselguhr, kieselgur and Celite, is a sedimentary rock primarily composed of the fossilized remains of unicellular fresh water plants known as Diatoms.
The typical chemical composition of diatomaceous earth is 86% silica, 5% sodium, 3% magnesium and 2% iron.
The De has a high porosity, with lower density, larger surface area, strong absorption, good suspending performance, it has relative incompressibility and chemical stability without any poison and smell.
Therefore, the diatomaceous earth and its products are used as a filter medium, especially for swimming pools. It is also used to filter beer,wine,glucose,syrups and sugar. Other industries such as paper, paints, ceramics, soap and detergents use it as a filling material.
It has been widely used to decolor and refine of the animal oil and fat, plant slipid and cosmetic raw material, petroleum industry, chemical industry for daily use, it has also been used in sewage disposal, filter noxious gas and catalyze petroleum in grain.
