Description of the concrete

The concrete is a kind of artificial material, which is made of cement as cementing material, the material of sand and gravel.

Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:SICOMA MPC planetary centrifugal mixer,concrete batching plants,concrete mixer,blocking making machine,concrete pump,etc.

The types and properties of concrete in different construction projects are very different, and if the performance and usage of the concrete produced by the production are understood, the adjustment of the equipment can be adjusted to improve the quality of concrete mixing, and it is not easy to make mistakes.

A hallmark of the performance of concrete is the strength, with length of 150mm cubes try block after 28d standard curing, by compression test to measure out. Commonly used intensity range is 10 - 60MPa, generally with the strength grade C20 - C60 said.

The work of fresh concrete, or as workability, is refers to the concrete mixture is easy to operation SICOMA Twin Shaft Compulsory Mixers, and uniform quality concrete mixing plant, forming a dense performance, is referred to as the technological properties of the concrete. Including the three aspects of mobility, viscosity and water retention. Flow is easy to flow, easy to fill the corners of the template. Cohesion refers to the structural properties of concrete is homogeneous and stable DMP planetary mixer manufacturer, less prone to stratification and segregation. The water is not prone to bleeding.

Working in the concrete construction of the greatest impact is mobility. The flow of plastic concrete with slump, it is generally in the range of 10 - 200mm. The greater the value is, the better the mobility is. Dry hard concrete to Vebe consistometer, which is generally in the range of 5 - 35s. The higher the value of the concrete, the higher the dry hardness.

The working nature of the design of concrete is determined by the engineering structure and construction method. Now the construction site more than the use of mobile or large flow of concrete, only the use of precast concrete components dry hard concrete.
