). Presumably the better activity of particular components in the CSA 1180 allows to produce more ettringite without disturbing the dissolution of initial material. The ettringite is known as forming an impermeable layer during the early cement hydration
Calorimetric measurements Calorimetry is a good method for studies on cement hydration during its first hours of action when chemical and physical processes occur most intensively. This technique bases on continuous measurements of heat released in
agents are presently used all over the world. In desert (hot and dry) climate regions, self-curing concrete will increase concrete strength. According to the study, internal curing improves cement hydration at the start of the procedure. Self
°C in nitrogen atmosphere, at the heating rate of 10 °C min −1 , the sample mass was 9–13 mg, measurements were carried out after 3, 7, 14 and 150 days of cement hydration
] on the behavior of SF on the steel slag powdered concrete, a decline in the CS was observed beyond 8% of addition of SF, which is due to the fact that Ca(OH) 2 produced upon cement hydration was exhausted as a result of which no C–S–H gel could be
