Factors determining the correlations between high strength concrete properties
چکیده انگلیسی

The factors that influence the reliability of the correlations between the properties of concretes with water-cement ratios between 0.26 and 0.42, tested at the ages of 7, 14, 28 and 365 days, were investigated. For this purpose, from the strength of correlations point of view; (i) the effect of the closeness of the sensitivities of the properties to the pore structure of cement paste and (ii) the effect of the closeness of dependences of the properties on the compositional factors were investigated. It was found that at the ages of 7 and 14 days, the closeness of dependences of the properties on compositional factors is the most important agent in determining the strength of correlations between them. However, at 28 days and after, the reliability of the correlations is mainly influenced by the closeness of the sensitivities of the properties to the pore structure of cement paste.
