Basalt fiber reactive powder concrete suitable for seasonal frozen area
Basalt fiber reactive powder concrete suitable for a seasonal freezing area is prepared from the following raw materials in parts by weight: 814 to 854 parts of cement, 198 to 220 parts of silica fume, 901 to 950 parts of quartz sand, 159 to 171 parts of water, 51 to 53 parts of a water reducing agent and 4 to 12 parts of basalt fiber. According to the invention, quartz sand is used as aggregate,the internal structure is more compact, gaps are smaller and do not communicate with each other, the concrete is not easily eroded by the outside, and the chloride ion erosion resistance of the concrete is improved. The used cement amount is small, the CO2 emission amount is small, and the environmental protection requirement is met. The doped basalt fibers and concrete are silicate materials andhave natural compatibility, so that the basalt fibers can be more easily and uniformly dispersed in the concrete. The micro-reinforcement effect of the basalt fibers on the concrete can inhibit the development of concrete cracks and reduce water entering the concrete, so that the frost resistance of the concrete is remarkably improved.
一种适用于季节性冰冻区的玄武岩纤维活性粉末混凝土，以重量份数计，包括以下各原料：水泥814～854份，硅灰198～220份，石英砂901～950份，水159～171份，减水剂51～53份，玄武岩纤维4～12份。本发明将石英砂作为骨料，内部结构更加致密，空隙更加微小且相互不连通，不易受到外界的侵蚀，提高了混凝土的抗氯离子侵蚀性。所用水泥量少、CO2排放量少，满足环保要求；本发明掺入的玄武岩纤维与混凝土均为硅酸盐类材料，二者具有天然的相容性，使玄武岩纤维能够在混凝土中更容易的分散均匀。玄武岩纤维对混凝土的微加筋作用可以抑制混凝土裂缝的发展，减少水进入混凝土中，从而使混凝土的抗冻性显著提高。
