Fine aggregate concrete prepared from TBM (tunnel boring machine) hole digging sand aggregate and preparation method of fine aggregate concrete
The invention belongs to the technical field of concrete, and particularly relates to fine aggregate concrete prepared from TBM hole digging sand aggregate and a preparation method of the fine aggregate concrete. The fine aggregate concrete prepared from the TBM hole digging gravel material comprises, by weight, 288-450 parts of cement, 180 parts of water, 0-90 parts of fly ash, 845-1076 parts of machine-made sand, 689-913 parts of broken stone and 3.5-6.2 parts of a water reducing agent, the machine-made sand and the broken stone are the TBM hole digging gravel material, and the particle size of the machine-made sand is 1t; the particle size of the broken stones is 5-10 mm. According to the method, aggregate with the particle size of 5-10 mm in TBM hole digging stone serves as coarse aggregate, hole digging stone with the particle size smaller than 5 mm serves as machine-made sand, the fine aggregate concrete is prepared, the problem that natural aggregate resources of the concrete are deficient is solved, meanwhile, the TBM hole digging stone can be rapidly treated, site resources of a construction site are saved, and pollution of the TBM hole digging stone to the environment is reduced.
本发明属于混凝土技术领域，特别涉及一种采用TBM洞挖砂石料制备的细石混凝土及制备方法。一种采用TBM洞挖砂石料制备的细石混凝土，以重量份计，包括288~450份的水泥、180份的水、0~90份的粉煤灰、845~1076份的机制砂、689~913份的碎石和3.5~6.2份减水剂，所述机制砂和碎石均为TBM洞挖砂石料，所述机制砂的粒径<5mm，所述碎石的粒径为5~10mm。本发明采用TBM洞挖石料中5~10mm粒径的骨料作为粗骨料，5mm以下的洞挖石料作为机制砂制备细石混凝土，以缓解混凝土天然骨料资源匮乏的问题，同时，可快速处理TBM洞挖石料，节省施工现场的场地资源，减少TBM洞挖石料对于环境的污染。
