Concrete is the structural material used in construction which is consisting of chemicals and is bonded with water and cement. The cement is made up of a chemical component of 8 materials like clay, shale, sand, iron ore, limestone, marl, chalk, and bauxite. The mixture is filled between the aggregate and spread effectively. The strength of concrete is calculated in kilogram per square centimeter or pounds per square inch. Concrete strength is affected especially by temperature, environmental factors and moisture.
Types of concrete:
Concrete is a pavement or structure with the lowest carbon footprint. It has unparalleled durability, resilience, strength, and longevity with maximized energy efficiency. Concrete which is specifically manufactured for construction projects of the customer and single product on site is known as Ready Mix Concrete. The mixture is made up of cement, water and aggregate like gravel, crushed stone or sand.
The positive concept of this RMC is lower costs, high-quality products, saving time in business and eco-friendly process. According to mixed designs, this concrete is manufactured in a batch plant. This concrete is generally delivered in two ways by cement manufacturers. The barrel truck mixture will be in the plastic state delivered to the construction site. Volumetric concrete mixtures will be dry and allow mixing the concrete in the construction site. It comes in three types where each type is determined by its ingredients with a specific mixture.
Shrink mixed concrete: The RMC is partially mixed in a plant mixer. During transit, in the truck, the remainder of concrete will be mixed in the mountain drum.
Transit Mixed concrete: It is also known as dry-batched concrete and all the basic ingredients including water also mixed in the truck mixer. Then the truck’s mixer drum rotates quickly and gives three variations.
Mixed at a job site – It gives a smooth mixture of 70 -100 revolutions at a speed of 12 -15 rpm by arriving at the construction site.
Mixed in transit – This mixture is continual 70 revolutions during transit, and then it slows down to 2 rpm and it finally discharges at the construction site.
Mixed in the yard – On the yard the mixture will be rotated at 12 – 15 rpm high speed for 50 revolutions during the transit period.
Central Mixed concrete: It is also called central batching plant concrete. Before loading into the mixer truck, the concrete is mixed thoroughly.
Advantages of RMC:
It is a good choice for a construction site due to its durability and consistency. These plants are manufactured with sophisticated equipment, consistent methods and strict controls on testing the material and process.
Efficiency: It is mechanized operations of a mixing plant that allows for higher output of concrete.
Lower consumption: The more appropriate handling and proper mixing practice help in lower consumption of cement.
Environmental friendly: The efficiency of production requires less energy and it helps in lower consumption of overall energy. So making it environment friendly in choosing concrete.
No need for storage: There is no need to store raw material on site because it will be delivered as it is ready to use.
Less chance of errors: The manufacturing process is automated; it does not require human involvement, so it will lower the chance of human error.
