بیشترA typical concrete mix contains 60 to 80 percent sand and gravel, also known as an "aggregate." This aggregate compound is more than filler. It plays an important part in the concrete's composition. The amount of sand and gravel in a bag of concrete determines the mixture's strength and texture.

بیشترIf a concrete screed (layer) is to be applied over a waterproofing membrane, the membrane is made rough by sand broadcasting. This is throwing a thin layer of sand by hand over the wet membrane (before it has set fully) so that the sand sticks to the membrane and provides a rough surface the concrete can adhere to.
