The advantages of C.S.A. cement - Caltra

The main phases of Portland cement are calcium trisilie (C3S) responsible for the initial strength at approximately 60% and calcium disilie (C2S) the main phase at approx. 20%, responsible for the strength over time. CSA cement does not form any free lime like Portland cement, which results in a lower alkali content. The pH of CSA lies at 10.5-11 whereas Portland …

1 Characteristics of calcium aluminate cement

Calcium aluminate cement offers a series of special characteristics. Thus, while its setting time is virtually identical to that of Portland cement, it hardens much more quickly. As a result, mortar and concrete made with calcium aluminate cement reaches strength, after only a few hours, which is about the same as that obtained at 28 days with

Development of Strength for Calcium Aluminate Cement

13.01.2019· In the present study, the development of strength in different calcium aluminate cement (CAC) mixture mortars with granulated ground blast-furnace slag (GGBS) was investigated.

Calcium Aluminate Cement Concrete| Concrete Construction

01.05.1982· Calcium aluminate cement concretes are not rapid setting. They are, however, rapid hardening; that is, they will develop as much strength in 24 hours as Portland cement concrete will achieve in 28 days. Calcium aluminate cement concretes should be cured for at least 24 hours, using a water spray or fog, ponding, wet burlap or a curing merane.
