Expansive Cement - an overview | ScienceDirect Topics

Depending on the tricalcium aluminate and gypsum content of ordinary portland cement, the maximum ettringite content of the hydrated product at early ages is approximately 15%; cementing systems containing industrial by-products, such as fly ash, with lime and gypsum may have a higher ettringite content of, for instance, 20% (Solem and McCarthy, 1992); expansive cements based on calcium

Górka Cement

Calcium aluminate cements (e.g. GÓRKAL 40, GÓRKAL50+) are made from two materials: bauxite and limestone.In high alumina cements (e.g. GÓRKAL 70, GÓRKAL 80) bauxite is replaced with alumina.In the process of production, pre-mixed raw materials are ground, and the slurry obtained is collected in tanks.Depending on the desired type of cement, we make corrections to the premix to obtain an

Heat evolution in hydrating expansive cement systems

11.05.2010· The calcium aluminate cement CAC 40 was ground together with special sulfate–lime sinter to produce an expansive additive to Portland cement (CEM I 42.5R). The expansive additive in the environment of hydrating cement transforms into ettringite at “right time” to give expansion before the final setting and hardening takes place. In the experiments the proportions of components of expansive mixture and basic cement were variable. The rate of hydration versus time for common cements …

Accelerators - Peramin - Imerys Aluminates

Accelerators also increase the speed of drying, particularly for formulations containing both Calcium Aluminate Cement and Calcium Sulfate binders wherein the drying results from the formation of ettringite. Cement accelerators are additives that can act in one of two ways, and sometimes both at the same time, they : Reduce the setting time of

Heat evolution in hydrating expansive cement systems

11.05.2010· The mixtures composed of the calcium aluminate cement and the lime–anhydrite sinter play successfully the role of expansive agent when used as an additive to Portland cement. The mixtures added as ca. 8% Portland cement replacement give a slight expansive effect; at the 12 or 16% cement replacement, the controlled expansion occurs. The volume changes are stabilized within the …
