The test results show that lowgradecement, replacement of cement by fly ash, and adding some carbon fibers are all helpful in improving the self-healing performance of concrete.
Through proper designed plan, high quality cement clinker was obtained by using lowgrade limestone as raw material. Samples were investigated by petrography analysis (PA) and X-ray diffraction (XRD).
以低品位的石灰石为原料,通过合理的配料方案,成功制备了性能优异的水泥熟料。
