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.
How Is Concrete Made?
Concrete is one of the most commonly used materials in construction and is made from a mixture of sand, water, cement, gravel and other materials. The process of making concrete is complex, but it can be broken down into three main steps: preparation, mixing and curing.
The first step in the process of making concrete is preparation. The materials used to make concrete must be carefully measured and combined in the correct proportions in order to ensure the strength and durability of the finished product. The most common ingredients used in concrete are cement, sand, gravel and water. The cement is the most important ingredient, as it acts as a binding agent and helps the other ingredients to form a strong and durable material.
The second step in the process is mixing. The ingredients must be thoroughly combined in order to create a homogeneous mix. A concrete mixer is used to mix the ingredients together until they achieve the desired consistency. Once the mixture is ready, it can be poured into forms to make different shapes and sizes, depending on the project.
The final step in the process of making concrete is curing. Once the mixture is poured into forms, it must be left to set and cure before it can be used. The curing process involves allowing the concrete to dry slowly
