Streszczenie
Solution proposed by authors of this paper is to change the type of coarse aggregate
into the aggregate of higher quality in order to achieve better strength for a given
concrete with a specifi c quantitative composition. Concrete classifi ed in 3 groups
was subjected to test: ordinary concrete of w/c = 0,70 and w/c = 0,58, and also
high strength concrete of w/c = 0,28. In each group concrete was made using four
different types of coarse aggregate. Comparing test results of strength properties
it should be stressed that there is a signifi cant effect of coarse aggregate on the
values obtained, as confi rmed by a statistical analysis. One can look for “concrete
strength” in other sources than those consisting in a unit increase of cement
content, through as shown, an appropriate choice of the type of coarse aggregate.
