【 摘 要 】

The focus of this work is on comparison the compression strength of the cementitious - limestone composite samples made according to different recipes. The study includes the results of own experimental research of the high performance cementitious - limestone composites as well as an analytical calculations of the mixture proportioning and designed compressive strength. Mixture proportioning based on the formulas of Funk and Dinger was determined. In the following step compressive strength based on the modified formulas Larrard was designed. Three test samples with dimensions of 100 x 100 x 100 mm were made for each recipe B1, B2, and B3. Information on the curing of research samples, cement, microsilica, limestone powder and limestone sand was presented. On the basis of experimental results after 7 days curing with using the proper amount of superplasticizer, the following section of the paper presents results after 28 days. Then a reference sample for the comparative analysis of the mixture proportioning was made and marked as B4. Based on the reference sample, the next samples with removed fractions (B5
