Indirect check of aggregate pore effects on concrete

Lydon, F. D. / Al-Mahfoud, H. H.

Abstract It is very difficult to quantify aggregate pores directly in a way that allows pore/water interaction to be accurately related to hardened concrete properties. This work examines, a number of aggregates through water absorption checks and gives results of tests on some concretes made with them. Three especially relevant concrete properties are examined, initial surface absorption, freeze/thaw behaviour and drying shrinkage; it is shown that aggregate absorption is reflected in these properties.
