What Makes Up Concrete?

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 Up Concrete?

Concrete is a construction material composed of cement, aggregate (generally a coarse aggregate made from crushed rocks such as gravel, limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures.

Concrete production is the process of mixing together the various ingredientscement, aggregate, water, and admixturesto produce concrete. Concrete production has a number of stages.

First, the cement (usually Portland cement) and aggregates are mixed together in a dry environment. The water and admixtures are then added and the resulting slurry is mixed until it reaches a uniform consistency.

The concrete is then placed into forms and allowed to cure or harden.

The properties of concrete depend on the proportions of the ingredients, the methods used to cure the concrete, and the desired properties of the finished product. Curing is a process that helps concrete maintain its strength and durability.

There are many methods of curing concrete, but the most common is to simply allow it to air dry. Concrete is a versatile material that can be used for a variety of construction projects.

It is strong and durable, making it ideal for foundations, walls, and floors. It is also easy to work with, making it a
