can effectively improve the strength of concrete

Sand soundness manufacturing standards , can meet different strength grade concrete configuration , according to tune Cha know, as technology advances , the actual sand is very mature technology and has become the scale Based and systematic , and the production performance is completely out of the sand to ensure concrete production requirements, ensure Paul architectural concrete meet safety standards .
Ready mix concrete plant fine sand , the particle shape is polygonal cube, good bite , can effectively improve the mix  Concrete strength ; particle number distribution, grading and stability. As raw material clean, clay content can be achieved Exemption . For the production of fine gravel , the Dan Ziqiang than the ordinary high pumping pressure loss, Slump of concrete mix plant be smaller. Each side C30 concrete pumping water saving 7 kg , cement 14 km Pounds ; its super good shape , small abrasion on equipment , mixers, tankers, pump and other equipment of wearing parts Prolong life for 1/ 3 of the time , the device can be significant savings in maintenance time and costs.
