Concrete pump is currently used to transport a lot of construction units of concrete machinery, machinery and equipment as a result of this can greatly improve the efficiency of construction, so much welcome to the construction side. So how special sand pumping concrete pump it? Specifically, we now introduce its pumping characteristics.
Experts pointed out: according to the thickness of the sand fineness modulus can be divided into four, especially sand is sand average particle size of 0.25 mm or less. How to use concrete pump pumped for this size of sand it?
1, for the ultra-high performance concrete pumping sand difficult issue special configuration by the preferred raw material, comprehensive measures to optimize the mix, the second plaster and pump controls, etc., usually this kind of technology to overcome special sand high performance concrete pumping hard, easy to crack and other technical problems.
2, special sand takes full advantage of high-performance concrete local materials, which can effectively reduce costs and conserve resources.
3, the use of "double-doped" technology can significantly improve the performance of concrete.
4, high performance concrete configuration of this construction method is usually applied to pumping basement foundation engineering and high-rise construction, high-rise concrete projects, therefore very welcome to the construction side of the subject.
Method of special sand pumping process is reasonable, mature technology, advanced, and the applicability and operability is quite strong, very consistent with national energy-saving and environmental protection requirements, the engineering applications show that this construction method has achieved remarkable economic and social benefits, development and application of key technologies with its originality and novelty, has reached domestic leading level, and therefore quite reliable.
