The future of fine stone concrete pump is broad

<p>Two embrittlement technologies based on electric pulses dis-charge or on microwave heating for concrete selective fragmentation are presented by us the professional <a href="http://www.dwconstructionmachine.com/">concrete mixer</a> manufacturer in the following study. First tests were performed on lab-made concrete samples representative of concrete waste from concrete mixer. Results showed that both techniques are efficient for concrete weakening and aggregates liberation (i.e. aggregates free of hardened cement paste). The electrohydraulic technique appeared to be less energy consuming with specific consumptions in the 1&ndash;3 kW h t 1 range compared to microwave treatment consumptions in the 10&ndash;40 kW h t 1 range. Additional tests carried out on concrete waste produced by the concrete <a href="http://www.daswellchina.com/products/concrete-mixing-plant/hzs60-ready-mix-concrete-plant.html">batch plant</a> characterized by an heterogeneous composition revealed that electric pulses discharge remains quite efficient for concrete fragmentation whatever the nature of the concrete blocks and their cementitious composition and with low associated energy consumptions. Further investigations to optimize the operating conditions of the concrete batch plant and to assess the quality of recovered products (aggregates <a href="http://www.daswellmixer.com/">concrete pump</a> <a href="http://www.concretemixerpump.com">concrete pumping</a>, cement paste) need to be performed in order to fully compare these techniques.</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:portable <a href="http://www.daswellmixer.com/product/Concrete%20_Mixer/20130929/24.html">cement mixer</a>,<a href="http://www.dwmixers.com/products/concrete-batching-plant/portable-concrete-batching-plant.html">batching plant</a>,We will provide you with the best product and service. <p> <p>And these results underline the efficiency of both weakening techniques with regards to aggregates liberation. This element is essential for concrete recycling since aggregates cleanliness is a guarantee that newly elaborated concretes from recycled aggregates will exhibit satisfactory mechanical properties for later use in construction.</p>
