Alite - Wikipedia

Hydration steps. Alite is the mineral in Portland cement responsible for setting and development of "early" strength. The other silicate, belite contributes "late" strength, due to its lower reactivity. Alite is more reactive because of its higher Ca content, and the presence of an oxide ion in the lattice.

cement | Definition, Composition, Manufacture,

Cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass.Setting and hardening result from hydration, which is a chemical combination of the cement compounds with water that yields submicroscopic

Sac de ciment gris ou blanc, chaux, mortier : les liants

Le ciment est un liant hydraulique, c'est-à-dire un matériau minéral finement moulu qui, gâché avec de l'eau, forme une pâte qui fait prise et durcit par suite de réactions et de processus d'hydratation et qui, après durcissement, conserve sa résistance et sa stabilité même sous l'eau.

The Effect of Sodium Gluconate on Pastes'

The goal of this paper provides better understanding of the effect of sodium gluconate (SG) on ordinary Portland cement (OPC) hydration behavior. Pastes' performances of ordinary Portland cement, including setting time at 20°C and 35°C curing temperature, mechanical strength, fluidity, and zeta potential are studied.

Relation chaleur d'hydratation du ciment : montée en

L'hydratation du ciment est une réaction exothermique. Ce phénomène est particulièrement surveillé lorsque des pièces massives sont construites étant donné l'élévation de la température, le développement de contraintes thermomécaniques et le risque de réaction sulfatique interne. Compte tenu de la grande variété des formules de béton, le choix d'un ciment ayant une basse

Portland Cement, Concrete, and Heat of Hydration Fig.1 demonstrates the effect of element size on concrete tempera-ture with time due to the heat of hydration. Temperature rises of 55°C (100°F) have been observed with high ce-ment content mixes.(2) These tem-perature rises cause expansion while the concrete is hardening. If the tem- perature rise is significantly high and the concrete
