Waste generation from the production of ready-mixed concrete

 · Ready-mixed concrete companies are responsible for a substantial part of concrete production in many countries. Waste is generated in every concrete truckload. A fraction of the concrete load is always returned to the plant, because not all concrete can be unloaded from the rotary drum as it is adhered to the internal surface.

What Is The Proper Method For Concrete Slurry Disposal?

If you have already collected the slurry in drums or pits, both AQUAmaxx and ECO-QUICKgel can help with your slurry disposal. Add AQUAmaxx to reduce the amount of waste and just decant the water. Then add ECO-QUICKgel to solidify the remaining concrete slurry. With both products, it is best to mix it in the concrete slurry to create a faster reaction and speed up processing time.

Concrete CO Fact Sheet

when compared to other building materials. As with any building product, production of concrete and its ingredients does require energy that in turn results in the generation of carbon dioxide, or CO2. The amount of CO2 produced during manufacturing and the net impact of using concrete as a building material is relatively small.

Concrete Wastewater Treatment - M.W. Watermark | M.W ...

These regulations could potentially lead to fines for concrete manufacturers because the production of concrete and the cleaning of equipment increases the pH levels in water. A filter press can efficiently recycle wastewater that is produced during concrete manufacturing and help producers avoid costly fines while reusing water.

Environmental impact of concrete - Wikipedia

The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the primary producers of carbon dioxide, a potent greenhouse gas.

Betonblock.com | Welcome

Disposing of leftover concrete is expensive, and a waste of material. In addition to the production of concrete blocks from new concrete, added value can be created from surplus concrete, by processing the waste into a simple but very efficient by-product that reduces processing costs and provides an optional source of income.
