An ever-evolving world needs constantly developing construction ways. In the present world, concrete is one of the most widely used construction materials. This can be due not alone to the large choice of applications that it offers, however, besides, its behavior, strength, affordability, durability, and flexibility play vital roles. Therefore, constructing-building works have faith in concrete as a secure, strong, and simple object. It is utilized in all sorts of buildings (from residential to multi-story workplace blocks) and infrastructure comes (roads, bridges, etc). Concrete is used for the development of foundations, columns, beams, slabs, and different load-bearing components. In this article, we are going to cover the following topics:
What is Concrete?
Composition of Basic Concrete Mix
Types of Concrete Mix
So, then let us dig into the details:
What is Concrete?
Concrete Definition: Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate (sand, gravel, stone, brick chips, etc.), water, admixtures, etc in specific proportions. The strength and quality are dependent on the mixing proportions.
The formula for producing concrete from its ingredients can be presented in the following equation:
Concrete = Binding Material + Fine & Coarse Aggregate + Water + Admixture (optional)
Concrete is a very necessary and useful material for construction work. Once all the ingredients -cement, aggregate, and water unit of measurement mixed inside the required proportions, the cement and water begin a reaction with one another to bind themselves into a hardened mass. This hardens the rock-like mass in the concrete.

Concrete is powerful, easy to create, and can be formed into varied shapes and sizes. Besides that, it is reasonable, low cost, and instantly mixed. It is designed to allow reliable and high-quality fast-track construction. Structures designed with the concrete unit of measurement are plenty durable and should be designed to face up to earthquakes, hurricanes, typhoons, and tornadoes. This is an incredible advancement. With all the scientific advances there are in this world, there still has not been a way of preventing nature's injury.
Composition of Basic Concrete Mix
If we evaluate the concrete composition to see what concrete is mad
Based on the variations in concrete materials and purposes, concrete can be classified into three basic categories-
Lime Concrete
Cement Concrete
Reinforced Cement Concretes
There are four concrete sorts to settle on from counting on the work being done. Such as-
Dry Ready Mix
Ready Mix
Bulk Dry Materials
Transit Mix
There are other various types of concrete for different applications that are created by changing the proportions of the main ingredients. Such as:
Regular Concrete
High-strength Concrete
Stamped Concrete
High-Performance Concrete
Self-consolidating Concretes
Vacuum Concrete
Shotcrete
Roller-Compacted Concrete
Glass Concrete
Asphalt Concrete
Rapid Strength Concrete
Polymer Concrete
Limecrete
Light-Transmitting Concrete
Brief Descriptions of all these 21 types of concrete are discussed below:
Lime Concrete
Lime concrete uses Lime as the binding material. Lime is usually mixed with surki and khoa or stones in the proportion 1:2:5 unless otherwise specified. The khoa or stones are soaked in water before mixing. Lime concrete is used mainly in foundation and terrace roofing.
Advantages of Lime Concrete
Lime concrete is cheaper than cement concrete.
Lime concrete is more workable than cement concrete.
Lime concrete has a lower heat of hydration, which makes it suitable for mass concrete works.
Lime concrete has good resistance to fire.
Lime concrete has good resistance to sulfate attack.
Disadvantages of Lime Concrete
Lime concrete has a lower strength than cement concrete.
Lime concrete is not as durable as cement concrete.
Lime concrete is susceptible to attack by frost.
Cement Concrete
Most engineering construction uses cement concrete composites as the main building material. It consists of cement, sand, brick chips, or stone chips of the required size. The usual proportion is 1:2:4 or 1:3:6. After mixing the required amounts of concrete materials, the mix is cured with water for 28 days for proper strength building.
