dry concrete. Definition. Concrete that has a low water content, making it relatively stiff. The effects are a lower water-cement ratio, less pressure on forms, lower heat of hydration, and a consistency that allows for placement on a sloping surface.
Cement is a binding agent made of limestone and clay; it has no strength and cannot be used to construct sidewalks or walls. Concrete is an actual construction material made of cement, rocks, sand and water -- and it is useful for building driveways, walls and sidewalks.
