UNIMIX Process

Concrete consists of a mixture of aggregate (sand and gravel),cement and water.
Concrete can be cast in almost any shape desired and once hardened it becomes a structural element. “Ready-mix” concrete (RMC) is a prescribed mix of aggregate, cement, water and often other admixtures and products that enhance the properties and characteristics of concrete.

Raw material used to produce concrete

  • Aggregates
  • Additives
  • Water
  • Cement
  • Air
Aggregates
Aggregates,which make up roughly 60% to 75% of ready-mix concrete’s volume,are obtained from quarries and aggregate banks.

Additives
Additives are solid or liquid chemical substances that can be added to raedy-mix concrete before or during preparation.Most commonly used additives either improve a hardened concrete’s durability a reduce of concrete’s waster content in an effort to shorten setting times.

Water
This is the mix’s vital fluid,which sets of 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 the different components come together to produce a uniform mass of concrete.Mixing time is registered from the moment material and water is poured into the cement mixer,and it begins rotating.While transporting concrete to a site,the cement mixer never stops revolving at a speed of two to six rotations per minute.
