Use of calcium chloride in the concrete doesn't cause entrainment of air, however when used with air entraining agents, it facilitates in producing more air content in less quantity of air entraining agent. 4. Freezing and Thawing Concrete containing calcium chloride hardens rapidly and develops early resistance to damage by freezing and thawing.

The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials.
Slag cement has been proven effective in decreasing chloride conductivity due to the additional C-S-H phases and higher alumina content that refine the microstructure [13]. Apart from the usage of SCMs, another field of interest has been towards the broad group of MgO-based cements and the usage of MgO as an expansive agent in concrete.
The role of chloride in cement has had a mixed history. On the one hand, chloride has long been used to accelerate cement hydration and strength gain. On the other, chloride deprives embedded steel of the corrosion protection normally developed in …

Calcium chloride can reduce resistance to this process. Effects of Calcium Chloride on Concrete. The addition of calcium chloride to a concrete …
Slag cement can resist attacks from both chlorides and sulfates and, at the same time, is an ideal option in case of any risk associated with alkali-silica reactions. Slag cement undergoes a hydration process that is pretty slow, which is responsible for its setting time to be high initially along with a high slump retention level.
In order to identify the influence of slag content on carbonation, chloride penetration resistance and their coupled effect, mortars with twelve cement blends in a range of 0–70% slag were evaluated based on chloride migration coefficient, accelerated carbonation and …
Calcium chloride accelerates cement's rate of hydration. A reduction in setting time helps protect freshly placed concrete. The effect is most noticeable in cool weather. Ready-mixed concrete sets more slowly at temperatures …
