The current world consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110 kWh/tonne, and around 40% of this energy is consumed for clinker grinding.There is potential to optimise conventional cement clinker …
2.1 Materials and Specimens. In the experimental study, waste concretes were used instead of limestone in Cem II B-L limestone tempered cement production. As waste concrete, concrete pressure test was performed on it and 15 cm cube samples were used (Fig. 1).The cement used in waste concrete production was Cem I 42.5 R. 5, 10, …

While estimating quantity of concrete for particular structural work, we normally consider 3-5% as wastage. But wastage of concrete more than that can increase the cost of project and may impact project progress. So, it is necessary to control the concrete wastage at site. Concrete wastage can be prevented by proper planning of pour.

The Mills Concrete culture centers on pushing the limits and excelling predominantly in client satisfaction.
Concrete milling is done to fix irregularities in concrete and create a smooth, level surface that provides plenty of traction. Why is this important? Irregular or uneven concrete surfaces are unsafe for vehicles and pedestrians. They can result in tripping hazards, poor tire traction, and other hazards. Milling helps to restore s…

In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.
