TYPES OF CONCRETE ⋆ Archi-Monarch

1) Introduction

Concrete is a composite material composed of cement, water, aggregates (such as sand, gravel, or crushed stone), and often other materials such as fly ash, slag, or chemical admixtures. When these ingredients are mixed together, they form a plastic mass that can be molded into any shape and then hardened into a strong and durable building material.

Concrete has been used in construction for thousands of years and is one of the most widely used building materials in the world today. Its popularity is due to its strength, durability, and versatility. It can be used in a variety of applications, including building foundations, walls, floors, and roofs, as well as in the construction of roads, bridges, and other infrastructure projects.
