The invention discloses low-shrinkage high-strength self-compacting concrete and a processing technology thereof, and particularly relates to the technical field of concrete materials, and the low-shrinkage high-strength self-compacting concrete comprises cement, water, a quick-setting early strength agent, aggregate and a supplement. The low-shrinkage high-strength self-compaction performance of the concrete can be effectively improved; the cement, the water, the quick-setting early strength agent and the aggregate in the formula are matched with one another, so that the basic performance of the concrete is ensured; the polypropylene/polyvinyl alcohol composite fiber can be prepared, and the toughness, the tensile strength and the elongation at break of the composite fiber are enhanced; therefore, the compressive strength, the crack resistance and the compactness of the concrete are enhanced; the nano titanium dioxide is compounded into the composite fiber, so that the self performance of the composite fiber can be effectively enhanced, and the action performance of the composite fiber on the concrete is further improved; meanwhile, after the nano titanium dioxide is doped into the concrete, the formation of gel in the concrete is promoted, and the compactness of the whole structure is improved, so that the mechanical property of the concrete composite material is improved.
本发明公开了一种低收缩高强自密实混凝土及其加工工艺，具体涉及混凝土材料技术领域，包括：水泥、水、速凝早强剂、骨料、补充剂。本发明可有效提高混凝土的低收缩高强自密实性能；配方中的水泥、水、速凝早强剂和骨料的相互配合，保证混凝土的基本性能；可制得聚丙烯/聚乙烯醇复合纤维，加强复合纤维的韧性、拉伸强度和断裂伸长率；从而加强混凝土的抗压强度、抗裂性能和密实程度；纳米二氧化钛复合到复合纤维中，可有效加强复合纤维的自身性能，进而提高复合纤维对混凝土的作用性能；同时混凝土中掺入适纳米二氧化钛后，促进了混凝土中凝胶的形成，提升了整体结构的致密性，从而提高了混凝土复合材料的力学性能。
