Tests for concrete strength are made shortly after it has been placed (7 to 90 days). It is always tested for acceptance at fairly early ages with respect to the concrete life and for this reason the strength obtained is less than the ultimate strength the concrete will attain. Flexural strength and compressive strength develop at different rates within the concrete. Except for the first few ...

Lightweight Concrete: Weighing in on the Differences

Standard concrete mixes typically use crushed natural stone as the coarse aggregate in the mix (along with Portland cement, water, and sand). The actual weight may vary slightly depending upon the local stone that is available, but generally, natural stone is relatively dense for its size, adding to the weight of the concrete mix.
