Ordinary concrete mixer can produce high quality concrete

<p>At present, the development trend of whole sandstone industry is stable. The exploition and application are controlled, and the artificial sand is stepping into the market. In construction sand, the artificial sand is added. The artificial sand produced by proper machines can be a better substitute to river sand. The sand should be sharp, clean and course. The grains should be of durable material. The grain sizes must be such that it should give minimum voids. It is proposed that mixed sand should meet for the standard of artificial sand <a href="http://www.daswellchina.com/products/concrete-mixers/mini-concrete-mixers.html">Mini concrete mixer</a>, which provides the outlet for dealing with the wast stone when digging river sand and also keeps the high quality of artificial sand.</p>Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:<a href="http://www.beton-mixer.com/products/jzr500ds-diesel-concrete-mixer-2.html">Diesel mixer beton</a>,<a href="http://www.daswellmachinery.com">concrete batching plant</a>s,concrete mixer,blocking making machine,concrete pump,etc. <p> <p>In some engineering projects, it is proved that ordinary concrete and pumping concrete are worked out with artificial sand, and the maximum pumping height achieves 400 meters. And also a span of 64 meters of prestressed concrete beams are made with artificial sand. Although the artificial sand is used widely in concrete structure, mortar and realitive products, its development can't keep banlance with big resistance.</p>
