THE ROLE OF AGGREGATES AND SANDS IN THE

A good concrete aggregate must be clean, chemically inert, and durable and roughly cubic in shape after crushing and of a size grade suitable to make concrete of desired physical qualities. Natural sand consists of loose grains which are commonly the result of the chemical weathering and/or physical breakdown of rocks.

The Benefits of Using Recycled Aggregate Products

Jul 13, 2020 While most of the time you get what you pay for in this world with recycled aggregate, you’ll get the same quality product at a lower price. It is a great way to spend less while maintaining the same results. Environmentally Friendly. Using this type of construction material reduces the need for furthering mining for new materials.
