As we all know, there are inevitable waste powder in gravel production line that many industries abundant them for useless. Then it is really useless or not. We will introduce you in the following passage.

Powder is inevitably produced in the process of gravel production with less than 75μm. It can be used in grading of sand, filling the concrete, hydration activity for improving the functions of concrete.

In the survey, appropriate powder can improve the performance, strength, durability of concrete. While stone powder is different from clay powder that has disadvantages for concrete.

Proper stone powder can improve the performance of concrete. Survey shows that concrete has better peaceability and more solid with 16% powder.

Test shows that powder has advantages and disadvantages to concrete. With low powder content, it will have low peaceability and stability; with high content it will have unreasonable grading and reducing the structure functions. And more powder will reduce the cement paste strength and reduce the concrete strength.

All in all, powder’s advantages for concrete is bigger than its disadvantages. We can improve concrete performance by controlling powder content. Also this saves natural resources which is the best choice.
