The Influence of Specimen Shape and Size on the PCC Compressive Strength Values
Abstract The paper discusses the effect of the specimen shape and size on the result of compressive strength tests performed on polymer cement concrete (PCC). The shapes of tested specimens included cylinders and cubes of dimensions as recommended in EN-206 when determining the compressive strength class of cement concrete. Moreover, apart from cubes of standardized size of 150 mm, the research included tests of cubes of size 71 mm and 100 mm. The tests were performed on PCC with two different polymer aqueous dispersions: styrene-acrylic copolymer and carboxylated styrene-butadiene latex. As a reference, the tests were performed on the (polymer-less) ordinary concrete (OC). The results showed that the general rule – the smaller is the specimen, the higher values of strength it obtains – cannot be directly applied to PCC. Also the relation between compressive strength measured on cylinder and cube specimens (both for OC and PCC) did not show the conformity with reference ratios for OC.
