Concrete strength - Understanding Cement

Almost everyone interested in cement is also concerned to at least some degree with concrete strength. This ebook describes ten cement-related characteristics of concrete that can potentially cause strengths to be lower than expected.

Cement Types

Construction documents often specify a cement type based on the required performance of the concrete or the placement conditions. Certain cement manufacturing plants only produce certain types of portland cement. What are the differences in these cement types and how are they tested, produced, and ...

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 ...
