POROSITY-STRENGTH RELATION IN CALCIUM ALUMINATE CEMENT PASTES

This study investigates the relationship between the compressive strength and the volume porosity of calcium aluminate cement pastes. The influence of mass fraction of lithium carbonate on compressive strength and porosity of calcium aluminate cement (CAC) has been investigated at different water-cement ratios. The functions proposed in the literature for different technical materials were tested on obtained strength and porosity data. Those functions have been a base for further development of more general functional dependence of strength and porosity for cement materials. An equation is developed to relate the strength and porosity for CAC pastes. The model uses effectively only one empirical constant and accounts for the composition of material. The model also describes well the high porosity range.
