本文从研究分析水泥混凝土的组成入手,合理调节各组分,掺入矿物掺合料,使混凝土获得高性能与高耐久性.在满足混凝土耐久性前提下,研究分析了掺粉煤灰,矿粉等活性矿物掺合料、外加剂对水泥混凝土性能的影响问题,并初步探讨了掺粉煤灰,矿粉高性能混凝土的强度与水胶比、砂率之间的关系。试验证明,高性能化后的水泥混凝土,其和易性和结构均匀性得到改善,强度与耐久性得到提高,从而赋予混凝土一系列高性能并提高了其绿色度。
This article starts with research and analysis of the composition of cement concrete, reasonably adjusts each component, and incorporates mineral admixtures to make concrete obtain high performance and high durability. Under the premise of satisfying the durability of concrete, the research and analysis of fly ash and minerals The influence of powder and other active mineral admixtures and admixtures on the performance of cement concrete, and the relationship between the strength of fly ash and mineral powder high performance concrete and the water-binder ratio and sand ratio were discussed. Tests have shown that the high performance of cement concrete improves the workability and structural uniformity, and the strength and durability are improved, thereby giving the concrete a series of high performance and increasing its greenness.
