HYDRATION OF CEMENT - University of Misan

HYDRATION OF CEMENT It is the reaction (s eries of chemical reactions) of cement with water to form the binding material. In other words, in the presence of water, the silicates (C3S and C2S) and aluminates (C3A and C4AF) form products of hydration which in time produce a firm and hard mass -the hydrated cement paste. There are two ways in which compounds of the type present in cement can ...

Concrete mixer - Wikipedia

A concrete mixer (often colloquially called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete.A typical concrete mixer uses a revolving drum to mix the components. For smaller volume works, portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to ...

Hydration kinetics modeling of Portland cement considering ...

The mechanism of cement hydration is discussed based on literaturereview. The model is then developed considering the effects of chemical composition and fineness of cement, water–cement ratio, curing temperature and applied pressure. The ultimate degree of hydration of Portland cement is also analyzed and a corresponding formula is established. The model is calibrated against the ...
