Polypropylene fibers and concrete projects have to do it, the characteristics of polypropylene fiber works, what is it, and why modern architecture to be used in polypropylene fiber engineering, today Sisiyuan Xiaobian take you to understand polypropylene fibers in concrete construction the steps:

First, according to the amount of each mixed concrete square, in accordance with the requirements of accurate measurement than with each addition of fiber weight, the proportion of appropriate, not too much;

Sand and gravel ready after the fibers are added. Recommended compulsory mixer. The aggregate together with the fibers added to the mixer. It should be noted should ensure that fiber is applied between the aggregate dry mix for about 30 seconds after the addition of water, wet mix about 30 seconds, in order to ensure uniform dispersion of the fibers in the mix.

After stirring for complete random sampling, such as fibers have been uniformly dispersed into a single wire, the concrete can be put into use, if the fiber bundles are still extended mixing time 20-30 seconds, can be used.
