The objective of designing a mix is to produce a concrete of required strength, a high cost of labour to obtain a degree of compaction with available equipment.

Sep 05, 2012 · There are a lot of ways to make a concrete pipe. In 1905 My great, great, great uncle John L. Ziedler came up with a pretty ingenious way to make pipe. it was a machine called a Packerhead, Europeans sometimes call this a radial-press.

Concrete Mix design helps to proportionate concrete's ingredients (cement,sand,aggregate & water) and help concrete achieve the desired strength, workability etc., Here is a detailed procedure for Concrete Mix design as per IS 10262:2009

Concrete Mix Design or Mix Design of Concrete is a procedure of determining the relative quantities and proportions of different ingredients of the concrete i.e. Cement, Water, Fine Aggregate, Coarse Aggregate, with the object of producing homogeneous fully compactable concrete having required Strength and Properties with economy.

The successful placement of concrete is dependent upon careful mixing, the This can vary from hand to machine mixing, with machine mixing being the most The types and volume of materials, the mix design, and the end result (i.e. 

: Top Ready Mix Concrete. We Machinery are very famous ready mix concrete batching plant manufacturers in China, We have our 

Concrete mix design is a procedure of selecting the suitable ingredients of concrete and their relative proportions with an objective to prepare concrete of certain minimum strength, desired workability and durability as economically (value engineered) as possible.

Machine Mixing. Coarse aggregates, sand and cement are put into the cement concrete mixer in the required proportion. For concrete of 1:2:4 mix 

A concrete mixer (often colloquially called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete.A typical concrete mixer uses a revolving drum to mix the components. For smaller volume works, portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to
