2.0 Batching and Mixing Concrete Mixing concrete is simply defined as the "complete blending of the materials which are required for the production of a homogeneous concrete" (Young, 267). This can vary from hand to machine mixing, with machine mixing being the most common.
All surface of forms or shutter facing concrete shall be treated with shuttering oil and dampen with water few minutes before concrete will be poured. Clean the slabs on grade using air compressor for dust or any small particles or deleterious materials that may impair the workability of concrete.
S = volume of concrete produced per batch in cubic f e e t ; V d = volume of concrete which the batch was de-signed to produce in cubic yard s . N O TE: A value for Ry greater than 1.00 indicates an ex-cess of concrete being produced, whereas a value less than this indicates the batch to be short of its designed vo l u m e .

8. PUMP AND PIPE-LINE METHOD. It is the most sophisticated method particularly suitable for limited space or when a large quantity of concrete is to be poured without cold joints. Pumping of concrete can be done @ 8 to 70 cubic meters per hour up to a horizontal distance of 300 meter and vertical distance of 90 meter.
Batching methods for rapid-hardening concrete. In order to mix rapid-hardening concrete different methods and site organisations are possible. Due to the fact that rapid-hardening concrete has a defined open time and has to reach a certain strength within a certain time the duration of batching and transporting should be as short as possible.
Aug 15, 2017 · It is the delayed bleeding, when the concrete has lost its plasticity, which causes undue harm to the concrete. Controlled re-vibration may also be adopted to overcome the effect of bleeding. Methods of Reducing Bleeding: 1) Add minimum water content in the concrete mix, use chemical admixtures to reduce demand to water for a required workability.
Batching. Mixing. Transporting and Handling. In this presentation we will be discussing the batching, mixing, transporting, and handling concrete. The discussion will begin with ordering concrete and the difference between performance and prescriptive specifications.
types of mixing methods and concrete mixers commercially available used by the concrete industry. There are two main types of mixers used: batch mixers and continuous mixers.
