Concrete is made of 3 main dry ingredients: cement, sand and stone. These 3 ingredients are mixed together to form dry concrete, which is what you find in a bag of Quikrete. When water is added to the mix, it reacts with cement to form a paste that eventually hardens. As concrete dries it grows stronger which is called curing.
