Cement, like flour, is an ingredient. To make concrete a mixture of portland cement (10-15%) and water (15-20%) make a paste. This paste is then mixed with aggregates (65-75%) such as sand and gravel, or crushed stone. As the cement and water mix, they harden and bind the aggregates into an impenetrable rock-like mass.
What Makes Concrete?
Concrete is the most widely used construction material in the world. It is a composite material made of cement, aggregate (usually sand and gravel), and water.
The cement is the binding agent that gives concrete its strength, while the aggregate provides the structure. Concrete is strong in compression, but weak in tension.
It is therefore often reinforced with steel or other materials to increase its strength. Concrete is a versatile material that can be used for a variety of applications.
It is often used as a foundation for buildings, roads, and bridges. It can also be used to create walls, floors, and ceilings. Concrete is also commonly used in the construction of dams, reservoirs, and canals.
The production of concrete is a complex process that involves the use of a variety of raw materials. The most important of these raw materials are cement, aggregate, and water.
Cement is a fine powder that is made from limestone and clay. The limestone is crushed and then heated to a high temperature in a kiln.
This process causes the limestone to break down into a substance called calcium oxide. The calcium oxide is then mixed with water to form a slurry. The clay is also heated in a kiln and then mixed with water to
