Experiment study on high-performance lithium-slag concrete

To use lithium slag(a kind of industrial by-product) in cement concrete, exert its potential, reduce cement dosages, lower engineering cost and improve performance of concrete, the paper studies the influence of lithium slag alone or the compounds of lithium slag and slag or stone replacing cement on the performance of concrete by analysis or experimental method. The result shows that lithium slag replacing a part of cement in concrete can improve the strength of concrete, applying lithium slag alone replacing cement can make high-strength pumping delivered concrete whose 28-day compressive strength is more than 100Mpa,concrete made using cement and lithium slag, cement and the compounds of lithium slag and slag or stone is very excellent in antifreezing, which can't be destroyed even through at 300 times freeze-thaw recycling. The conclusions of the study enhance the value of lithium slag, providing a approach for application of lithium slag and being helpful to the preparation of high strength and high performance concrete.
