Importance of Gravel and Sand for Concrete | Hunker
Though water makes cement easier to pour and helps it to harden, cement and water by themselves don't hold together very well. In fact, cement isn't typically used without sand and gravel. The addition of sand makes cement more binding. Cement mixed with water and sand becomes mortar, the paste used to hold bricks together. Once you add gravel to the mix, it becomes concrete....
The concrete conundrum
discovery of Portland cement, the key ingredient used in concretes today. The process of roasting, and then grinding to a powder, limestone and clay to make 'artificial stone' was patented in 1824 by Joseph Aspidin of Leeds, UK, and later refined by his son William into a material very close to the cement used today. The main reaction occurring in Aspidin's kiln was the formation of ......
