Mixing Of Concrete | Concrete Mixing Methods | Hand Mixing

Mixing of Concrete is a very complex process. For making good quality concrete, we just have to follow some standard process of mixing its ingredients. It just does not up to making concrete, but making good quality concrete is important.. Production of good quality and bad quality of concrete includes the same material, but the proportion and mixing method can be a differentiating factor.

Methods of Transportation of Concrete - Dumpers, Trucks

Feb 09, 2017 · Transporting the concrete mix is defined as the transferring of concrete from the mixing plant to the construction site. The main objective in transporting concrete is to ensure that the water-cement ratio, slump or consistency, air content, and homogeneity are not modified from their intended states. Concrete produced from a mixer is required to be transported to the

Methods of Batching Concrete - The Constructor

To make 1:1:2 ratio concrete mix according to volume batching, one should take one bag of cement (35 liters), 1 gauge box of fine aggregate (35 liters) and 2 gauge boxes of fine aggregate (70 liters). If the water-cement ratio is 0.5, then half of the volume of cement which is 25 liters of water should be taken. Fig 1: Gauge Box or Measuring Box.

4 Concrete Processing | Nonconventional Concrete

Batch mixing and concrete placement are usually separated by both space and time. There is time between the mixing of the constituents until the plastic concrete is placed in the forms or machines to take on final net-shape. The stiffness of the concrete is increasing during this interval, and the workability of the mix is decreasing.

Types of Concrete Batching Plant: Know Before Concreting!

Feb 22, 2019 · Concrete is the most popular construction material. For the concrete to be durable and attain the desired strength the ingredients of concrete must be mixed in a definite proportion. Batching is the process in which the quantity or proportion of materials like cement, aggregates, water, etc. are measured based on either weight or volume to prepare the concrete mix.
