In the laboratory, and when designing concrete mixtures, we really talk of only two moisture conditions. The first, oven dry, means exactly what it sounds like. The aggregates, which contain pore spaces of their own, have those pore space filled only with air. The second, saturated surface dry condition, is defined as the condition in which all ...

More cost effective than natural sand: Manufactured sand can be produced in areas closer to construction sites, bringing down the cost of transportation and providing an assurance of consistent supply. Compliant with the new European Standards: Manufactured sand can be used as aggregates in screed and concrete mixes, as per EN13139. It can be used as a replacement or as a blended mixture with natural sand.
