摘要
以宁夏当地丰富的废弃物煤矸石复合粉煤灰及矿渣,试验对比了掺与不掺煤矸石及混合材的混凝土强度;对比了外加剂(减水剂、引气剂等)对复合混凝土的增强效果.试验证明,以煤矸石复合其他矿物掺和料能加深水泥的水化过程;当煤矸石与其他矿物掺和料达到合适的配比时能将混凝土强度提高1个等级.
This paper aimed at abundant gangue, fly ash and slag in Ningxia local industrial waste resides, compound fly ash and slag a certain amount in the concrete, by testing and contrasting the strength of concrete before and after adding the gangue and composite materials; contrast the effect of admixtures (water-reducing and air entrainment agents) on the improvement of compound concrete. The test showed that a combination of gangue and other mineral materials can promote hydrating of cement and increase strength of concrete.
