Alternative Raw Materials For Making Cement

Eco-Friendly Alternatives To Traditional Concrete

Jul 18, 2019AshCrete is a substitute for traditional concrete that heavily utilizes recycled fly ash. Fly Ash is mixed with lime and water to make it strong and durable, similar to conventional cement. Use of fly ash in Ashcrete makes it an environment friendly alternative, since it can replace cement which in turn leads to reduced CO2 emissions.

Alternative Raw Material Sources For Cement Production

This study was therefore to investigate alternative source of raw material for the production of cement. These investigation was geared towards industrial waste and Agricultural residues. Agricultural residues are composed of organic constituents such as cellulose, lignin, fibre and small amounts of crude protein and fat.

Using alternative raw materials CemNet

Apr 18, 2012Switching from limestone to alternative raw materials can affect the production process in several ways There are occasions when an alternative material appears at first to be attractive for use in the cement clinker raw mill but when explored further its value seems to diminish relative to the status quo.

Raw Material Substitution Cembureau

The cement industry already replaces some of its raw natural resources with waste and by-products from other industrial processes. Selected waste and by-products containing useful elements such as calcium, silica, alumina and iron can be used as raw materials in the kiln, replacing natural substances like clay, shale and limestone.

Alternative Raw Material Sources for Cement Production

The cost of exploiting the limestone: the major raw material constitute about 50% of the production cost which results in the high cost of cement. It therefore becomes imperative to bring down the cost of cement by investigating into alternative source of raw material for cement production and hence this project.

How Cement Is Made Portland Cement Association

The finely ground raw material or the slurry is fed into the higher end. At the lower end is a roaring blast of flame, produced by precisely controlled burning of powdered coal, oil, alternative fuels, or gas under forced draft. As the material moves through the kiln, certain elements are driven off in the form of gases.

Alternative Raw Materials Industrial Efficiency

Alternative Raw MaterialsTechnologiesMeasures. As the calcination energy demand is estimated to be 1.9 GJ/t-clinker, substituting 10% of clinker with steel slag will reduce energy consumption by 0.19 GJ/t-clinker. Equipment costs are mainly for material handling and vary between US $200,000 and $500,000 per installation.
