Ultra-high performance concrete mixed with glass fibers and plastic steel fibers and preparation method of ultra-high performance concrete
The invention relates to ultra-high performance concrete mixed with glass fibers and plastic steel fibers and a preparation method of the ultra-high performance concrete. The concrete is prepared from the following raw materials: a super plasticizer, the glass fibers, the plastic steel fibers and other components, wherein the mass ratio of the super plasticizer to the glass fibers to the plastic steel fibers is 12: (5-20): (2-7); the preparation method comprises the following steps: uniformly stirring the water and the super plasticizer; adding Portland cement, silica fume and quartz powder, and uniformly stirring; adding quartz sand, and uniformly stirring; adding glass fibers and plastic steel fibers, and uniformly stirring to obtain a mixture; and pouring, forming and curing the mixture to obtain the ultra-high performance concrete mixed with the glass fibers and the plastic steel fibers. Compared with the prior art, the fiber-blended ultra-high performance concrete prepared by the invention has the advantages that the compressive strength reaches 100 MPa or above, the problem of corrosion of the steel fibers is fundamentally solved, and the glass fibers and the plastic steel fibers are soft and easy to operate and do not scratch the skin of a human body in the use process.
本发明涉及一种混掺玻璃纤维和塑钢纤维的超高性能混凝土及其制备方法，该混凝土的原料包括质量比为12:(5‑20):(2‑7)的超塑化剂、玻璃纤维和塑钢纤维，以及其他组分；该制备方法为将水和超塑化剂搅拌均匀后；加入硅酸盐水泥、硅灰和石英粉，搅拌均匀后；加入石英砂，搅拌均匀后；加入玻璃纤维和塑钢纤维搅拌均匀后，得到混合物；将混合物浇筑、成型、养护后，得到混掺玻璃纤维和塑钢纤维的超高性能混凝土。与现有技术相比，本发明制备的混掺纤维超高性能混凝土抗压强度达100MPa以上，从根本上解决了钢纤维的锈蚀问题，且玻璃纤维和塑钢纤维柔软易操作，使用过程中不会划伤人体皮肤。
