Cement And Concrete With Precise Manufacture

Aluminum Forms for Concrete Construction -

The Precise Forms 36″ modulation reduces the number of forms handled by 33% over the traditional 24″ wide plywood forming systems. This cuts labor costs and minimizes crew fatigue. A 36″ wide aluminum form has 50% more square footage of face sheet compared to a 24″ wide steel and plywood form with approximately the same weight.

The Manufacture of Portland Cement

The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1 - Quarrying The raw material for cement manufacture is a rock mixture which is about 80% limestone (which is rich in CaCO3) and 20% clay or shale (a source of silica, alumina and Fe2O3). These are quarried and stored separately.
