What is concrete made up of? The answer to this common question is aggregates, additives, water, and cement. This combination creates the second the most consumed material in the world, second only to water. It is the most consumed man made material in the world due to its resiliency and versatile applications used in everyday life.

Raw Materials Used to Produce Concrete:

• Aggregates make up roughly 60% to 75% of ready-mix concrete’s volume, are obtained from quarries and aggregate banks.
• Additives are solid or liquid chemical substances that can be added to ready-mix concrete before or during preparation. The most used admixtures typically improve concrete’s durability or reduce its water content in an effort to shorten setting times.       
• Water is the mix’s vital fluid, which sets off a chemical reaction when it comes into contact with the cement.
• Cement no other material rivals cement’s importance in the mix; it’s the ingredient that gives concrete its resistance. 

Concrete Mixing

During the mixing phase, these four components come together to produce a uniform mass of concrete. Mixing time is registered from the moment material and water are poured into the cement mixer, and it begins rotating.

Transporting

While transporting concrete to a site, the cement mixer never stops revolving at a speed of two to six rotations per minute.
