Materials Used to Make Concrete

What are the basic materials used to make concrete?

a. portland cement, rocks, admixture
b. portland cement, aggregates, water
c. portland cement, water, grout
d. portland cement, mortar, water

Answer:

The basic materials used to make concrete are Portland cement, aggregates, and water.

Explanation: The basic materials used to make concrete are Portland cement, aggregates, and water. Portland cement acts as the binding agent in concrete and is made by heating limestone and clay in a kiln. Aggregates, such as rocks or gravel, are added to give concrete strength and stability. Water is necessary for the chemical reaction that occurs between the cement and aggregates, forming a solid and durable material.

Concrete is one of the most commonly used construction materials due to its strength, versatility, and durability. By combining these basic materials in the right proportions, builders can create structures that are reliable and long-lasting.
