The Function Of Sand Producing Concrete. 5 hours ago Concrete is formed of two parts: cement (accountable for 8% of total global CO 2 emissions) and aggregate (essentially made of gravel and sand). In spite of the abundance of sand across the globe, the availability of sand for the production of concrete is quite restricted since sand particles ...

2018-4-13 Sand, the most common aggregate, is then added to the cement. The sand binds everything together and makes an artificial rock. The sand also enhances concrete's most favorable properties such as thermal expansion, compression strength, and tensile strength. Water acts as a lubricant and is key to mixing, setting, laying, and hardening concrete.
