Abstract: Several standard methods are used for determining some mechanical properties of two groups of finegrained concretes (ordinary – OPC and composite CPC) as a function of the pore volume (Vp). The latter varies within a broad range of the investigated water/cement ratios. It has been shown that both compressive strength logarithm (CC) and microhardness logarithm (MHV) are interrelated with the changes of pore volume and depend strongly on its size. The higher values of CC and MHV for CPC are due to the combined participation of the active additive and the acidic granulated slag. Their contribution to the enhanced hydration and dense cement structure formation is analyzed and the character of the СС=f(MHV dependence is determined. Microhardness measurements can be used for express indirect assessment of basic mechanical parameters of different composite construction elements.
