Readymix concrete is often misunderstood, especially when compared to cement. This SACAA overview explains what readymix concrete is and clarifies the key differences between cement and concrete in practical terms. In South Africa, many people use the term “cement” when they actually mean concrete. The guide explains that concrete is a mixture of materials including sand, stone, water, cement, and sometimes ash. Understanding this distinction is important for construction, infrastructure development, and material selection. The article provides a simple, non-technical explanation to help industry professionals and the public better understand how these materials are used.
