The effect of igneous rock aggregates on flexural and compressive strength of concrete

Turkiewicz T., Góra J., Piasta W.

Structure and Environment

2013

Vol. 5, no. 2

12--18

The test results presented concern ordinary concretes containing 5 coarse crushed aggregates made from igneous rocks and one made from gravel. The two aggregates i.e. granite and basalt were from southwest Poland and three i.e. granite, basalt, granodiorite were from West Ukraine. Natural gravel was comparatively tested as well. The tests of aggregates dealt with bulk density, grinding ratio, content of irregular grains and content of mineral powder. Flexural and compressive strength of concretes were tested after 28 and 365 days. Better strength properties of concretes containing Polish aggregates in relation to comparable petrographic Ukrainian aggregates were found.
