By introducing dimensionless concrete composition content indicators, the structural composition of concrete mixes can be graphically described, opening the way for analysing the effects which influence the performance properties of fresh and hardened concrete mixes using an approach that differs slightly from what has gone before. The present paper deals with the continuation of the observations and the analysis of the results. By an analysis of factors that have influence on the compressive strength, it is possible to make further progress towards an explanation for the two problems mentioned in the literature (summarised in the first part of the present series of papers), which have never so far been fully understood. The analysis of drying shrinkage deformation tests of small-scale prisms prepared during the laboratory experiments is also presented, and the relationships between the concrete composition content indicators and the drying shrinkage deformations in hardened concretes are highlighted. An interesting parallel is revealed in the effects that influence compressive strength and those that influence drying shrinkage deformation, and this provides an opportunity to estimate drying shrinkage deformation in advance from the concrete composition content indicators.
