Lecture 1. Introduction to concrete technology

Concrete is a mixture of cement (9 – 15%), water (15 – 16%), fine aggregate (sand, 25 – 30%), coarse aggregate (gravel or crushed rocks, 30 – 45%), air (2 – 6%) and chemical admixtures in which the cement and water have hardened by a chemical reaction

Concrete Vs. Asphalt Roads — Which Is Better? –

Concrete is made using aggregate (like crushed rock and sand), along with cement and water. The cement acts as the binder in concrete, holding the aggregate together. As the mixture dries, it forms a stiff, unforgiving solid that is prone to cracking and breaking, especially if the surface beneath it is not perfectly smooth.
