How To Fully Mix Concrete With Artificial Sand

Summary

With the expansion of China's infrastructure scope, the amount of concrete containing sand and gravel has increased year by year, the natural sand resources

With the expansion of China's infrastructure scope, the amount of concrete containing sand and gravel has increased year by year, the natural sand resources in local rivers have been nearly depleted state, in recent years, the national policy is also vigorously promoting artificial sand, accelerate the pace of artificial artificial sand application in the project. The amount of sand in concrete covers 30 percent, so the quality of sand stone and the dosage often determine the quality of concrete, and whether the quality of concrete is up to standard has a certain impact on the safety of construction projects, the artificial of sand in the configuration of concrete contains very high requirements. So what are the precautions for the preparation of concrete for the artificial sand?

Requirements for the artificial sand production process

First of all, we should go to the sand plant on-site inspection artificial sand, we must ensure the quality of the artificial sand quality. Because the artificial artificial sand is by the sand-making machine as a support point, crusher for the front line, transportation, feeding equipment for the auxiliary integration and production, involving more links, so to each stage of production is strictly controlled, in order to ensure that the final product grain type and grade match ingestand and standards. In addition, artificial sand in line with the standard of construction sand, the amount of stone powder is also one of the important indicators, before the crushing section, add a mud removal process, not only can prevent stone powder from being flushed, but also make the artificial sand stone powder content control within seven percent

What performance is required for concrete raw materials

As one of the components of concrete, the national building sand, its pressure resistance, moisture content, mud content, particle size, fine module, powder content should be within the standard range, to prevent the use of the project, concrete cracking or shrinkage and other issues. Because the finished sand is not easy to stack too high, so the number of sand field in the yard must be sufficient, in accordance with the order of finished output in order to load the car, in the loading phase to timely control of water content, so as not to too much moisture sticky carriers or warehouses, to avoid delay in the feed.

Under the phenomenon of increasingly popular artificial sand, doing a good job of sand quality is an important prerequisite to expand the scope of infrastructure projects, is to the environmental protection policy of the strong close, and eventually form a comprehensive benefit for development.
