Concrete is a composite material made up of cement, water, and aggregates.

• Types of concrete include plain, reinforced, pre-stressed, and lightweight.

• Materials used for concrete include cement, water, aggregates (sand, gravel, crushed stone), and admixtures (chemicals added to improve properties).

• Different types of aggregates can be used to achieve different properties, such as strength, durability, and workability.

• Admixtures can be used to improve properties such as workabili...read more

Mix ratios for grade of concrete

• Mix ratios for concrete vary depending on the grade of concrete required

• For example, for M20 grade concrete, the mix ratio would be 1:1.5:3 (cement:sand:aggregate)

• Higher grade concrete requires a higher proportion of cement in the mix

• The mix ratio should be carefully calculated to ensure the desired strength and durability of the concrete

RMC offers better quality, consistency, and efficiency compared to site mix.

• RMC is produced in a controlled environment, ensuring consistent quality.

• It reduces the need for on-site storage of raw materials and equipment.

• RMC reduces the risk of human error and increases efficiency.

• It also reduces the amount of waste generated on-site.

• RMC can be customized to meet specific project requirements.

• Site mix, on the other hand, is prone to variations in quality and consistency.

• It req...read more

The slump test is a method to measure the workability of fresh concrete.

• A slump cone is filled with fresh concrete and compacted in three layers

• The cone is then lifted and the amount of slump is measured

• The slump value indicates the consistency of the concrete

• The test is performed in accordance with ASTM C143 or EN 12350-2 standards
