Sand mining in world rivers (FINAL)LC

2020年10月30日 that by better understanding and communicating the impacts of sand mining – aggregate extraction encompasses sand, gravel, pebbles or cobbles, but is collectively referred to as sand mining – on rivers, the organisation can influence key decision-makers to ensure that extraction is done sustainably.

RACBase: A cloud-based database of recycled aggregate

The changeable service environment can induce durability degradation of concrete structures. Compared with natural aggregate, recycled aggregate has a higher porosity and water absorption, and a lower apparent density [4], which leads to the durability of recycled aggregate concrete (RAC) being generally lower than that of conventional concrete ...

Sand, rarer than one thinks - UNEP Sioux Falls

The environmental impact of in-stream mining might be avoided if the annual bed load were calculated and the mining of aggregates restricted to that value or less (Ashraf et al., 2011).
