The Effects Of Temperature On Concrete During Installation

Oct 04, 2017 Temperatures during the manufacture and placing of concrete can affect its setting time and final strength. When temperatures are high, this can lead to cracks, and many mass concrete works use chilled water for the mixing process to control the temperature of the concrete and reduce the chances of cracking and damage.

Cement Milling Understanding Cement

Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris 2CaSO 4.H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4). This is calcium sulfate with a

Cement clinker

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
