An Investigation into the Use of Manufactured Sand as a
2/6/20161 Introduction In many countries sources of natural sand for use as an aggregate in construction are becoming scarce as sand pits are exhausted and environmental legislation prevents dredging [1 2 3] This is driving the need to source alternative aggregates such as those from construction and demolition waste

Some mechanical properties of normal and recycled
recycled concrete aggregate was 3 to 5 times more than that of natural aggregate in the saturated surface dry state due to the porosity of mortar around the recycled concrete aggregate Arum [6] found that the workability of aggregate concrete is better than that of recycled aggregate concrete at the same water/cement (w/c) ratio
