摘要:
以普通混凝土和橡胶再生混凝土为研究对象,通过掺入硅粉和纤维材料研究强化环保型混凝土抗压性能的方法。用再生混凝土100%等体积代替粗骨料,用橡胶颗粒20%等体积代替细骨料,内掺10%(质量分数)或外掺3%(质量分数)硅粉以及掺入聚丙烯纤维或钢纤维,制备了4组12个混凝土立方体试件,通过轴压试验研究了混凝土试件的破坏模式、抗压强度和工作性能。结果表明:与单一掺入硅粉相比,硅粉和聚丙烯纤维的复合掺入能进一步强化混凝土的抗压性能;硅粉的掺入可以强化浆体与橡胶颗粒间的界面性能,提高钢纤维橡胶再生混凝土的抗压强度;硅粉和纤维材料对混凝土的工作性能有负作用,其复合掺入时建议采用适量的减水剂。
Abstract:
Taking normal concrete and rubber recycled concretes as the research objects, the mothed of reinforcing compressive performance of environmental concrete was studied through adding silicon powder and fiber materials. Recycled concrete aggregate was introduced into the concrete mixture by 100% volume fraction to replace coarse aggregate. The crumb rubber content was at levels of 20% by mass fraction to replace fine aggregate, and the silica fume content was used at levels of 10% by mass fraction to replace cement or at level of 3% by mass fraction in addition, and polypropylene fiber or steel fiber was added to the concrete. A total of 4 groups of concrete specimens (12 cubes) were casted. Through axial compression tests, failure modes, compressive strength and workability of the concrete were analyzed. The results indicate that comparing with the concrete with only adding silica fume, the incorporation of both fiber material and silica fume can further improve the compressive performance of concrete. The addition of silica fume can strengthen the interfacial performance between paste and crumb rubber, and improve the compressive strength of rubber and steel fiber reinforced recycled aggregate concrete. However, both silicon fume and fiber materials have negative influences on the workability of concretes, and a certain content of water reducer is supposed to use in the mixture.
