Abstract: Shrinkage strain, compressive strength and water absorption of high performance concrete (HPC) are estimated to high accuracy with linear equations using the w/c ratio and paste volume as variables. A paste volume reduction, thus an increase in coarse aggregate fraction, improves the HPC properties. These changes most likely result from: 1) adsorption of water on a greater surface of aggregate, leading to bulk paste desiccation and densifying and reduction in actual w/c ratio and width of aggregate-cement paste interfacial transition zone; 2) beneficial influence of larger volume of coarse aggregates produced from rocks of high strength and low water absorption.
