摘要：分别研究了矿物掺合料（粉煤灰、矿渣）、养护方式对普通混凝土比强度的影响；陶粒、橡胶颗粒、聚苯颗粒对轻骨料混凝土比强度的影响以及陶砂、钢纤维对(超)高强混凝土比强度的影响。结果表明：适量掺入矿渣，普通混凝土28 d的比强度提高更大；轻骨料混凝土的比强度分别随陶粒、橡胶颗粒、聚苯颗粒取代率的增加而降低，其中，陶粒对轻骨料混凝土比强度的不利影响相对较小；当掺入1.5%的钢纤维和18%的陶砂时，（超）高强混凝土的比强度提升幅度最大。 Abstract: The influence of mineral admixtures (fly ash, slag) and curing methods on the specific strength of ordinary concrete, and the influence of ceramsite, rubber particles, and polystyrene particles on the specific strength of lightweight aggregate concrete, and the influence of ceramic sand and steel fiber on the (super)high-strength concrete were studied. The results show that the proper amount of slag can improve the specific strength of ordinary concrete at 28 d age. And the specific strength of lightweight aggregate concrete decreases as the volume of aggregates replaced by ceramsite, rubber particles, and expanded polystyrene increases. The adverse effect of ceramsite on the specific strength of lightweight aggregate concrete is relatively small. When mixed with 1.5% steel fiber and 18% ceramic sand, the specific strength of (super) high-strength concrete increases the most.

The results show that the proper amount of slag can improve the specific strength of ordinary concrete at 28 d age. And the specific strength of lightweight aggregate concrete decreases as the volume of aggregates replaced by ceramsite, rubber particles, and expanded polystyrene increases. The adverse effect of ceramsite on the specific strength of lightweight aggregate concrete is relatively small. When mixed with 1.5% steel fiber and 18% ceramic sand, the specific strength of (super) high-strength concrete increases the most.
