What Is Fresh Concrete?

Properties of Fresh Concrete

• Workability.
• Temperature.
• Water Cement Ratio.
• Segregation.
• Bleeding.
• Plastic shrinkage.
• Setting Time.
• Hydration.

1. Workability of Fresh Concrete

Factors Affecting Workability

• Influence of Mix Proportions
• Influence of Aggregate Properties
• Influence of Admixtures
• Effect of Time

Test of Workability for Fresh Concrete

• Slump Test
• The Competing Factor Test
• The Vee-Bee Consistency Test
• The Flow Test
• Spread / Flow Table
• Kelly Ball
• Ouimet
• K- Slump
• Visual Assessment

4. Segregation of Fresh Concrete

Harmful Effects Due to the Segregation of Concrete

• To comb the concrete honey.
• The high permeability of concrete.
• Low compressive strength.
• Poor finishing of surfaces.

5. Bleeding of Fresh Concrete

Prevention of bleeding in concrete

• Bleeding can be reduced with appropriate proportions and uniform and complete mixing.
• Bleeding is reduced by the use of finely divided pozzolanic materials, making a long way to cross the water.
• The air-penetrating agent is very effective for reducing blood.
• Bleeding can be reduced by the use of fine cement or cement with low alkali content.
