CRM, a new high-effective mineral admixture for concrete, is developed recently from industrial residue, and the systematical studies on CRM’s various properties have been performed. The laboratory tests, industrial tests and field applications have shown that CRM can be used as inorganic cementitious material to replace cement, and is also an excellent supplementary cementitious material tor high performance concrete (HPC).展开更多

High-quality activated carbon was prepared by single factor and orthogonal experiments. Iodine adsorption and methylene blue adsorption were used as performance indicators. As prepared activated carbon was characterized by XRD, XPS and SEM. The results showed that the optimized electrode material was prepared under an impregnation ratio of 1:2, activation temperature of 800°C and activation time of 100 min. The yield of activated carbon was 49.48%, the iodine value was 1667.13 mg/g and the methylene blue value was 429 mg/g. The specific surface area measured by the automatic porosity analyzer is 1221 m<sup>2</sup>/g, and the mass-specific capacitance is 215.7 F/g under current density of 0.1 A/g.展开更多
