Particle shape is polygonal cube

The production of 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 .Stationary conacrete plant of fine gravel , the Dan Ziqiang  than the ordinary high pumping pressure loss, Slump of concrete can 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 , concrete mixer machine significant savings in maintenance time and costs. For the concrete Enterprises , fine sand and gravel production for own consumption , stable quality , no longer as raw material quality is poor, unstable Given problem and headache
