High-strength concrete with ductility and preparation method thereof
The invention discloses high-strength concrete with ductility and a preparation method thereof, and relates to the technical field of building materials, the high-strength concrete is mainly applied to thin composite floor slabs, and the high-strength concrete is prepared from the following raw materials in parts by weight: 200-250 parts of water, 460-480 parts of cement, 480-500 parts of sand, 500-520 parts of waste concrete, 750-780 parts of stones and 60-80 parts of reinforced fibers; when the reinforced fiber is subjected to external force, the spiral structure can prevent longitudinal propagation of cracks, meanwhile, the basalt matrix can avoid interlayer shear failure of the spiral structure on the surface so as to absorb more acting force, a side chain of polysilane on the surface contains carbon-oxygen double bonds and long-chain alkyl, and the carbon-oxygen double bonds interact with hydrogen on the long-chain alkyl so as to absorb more acting force. The spiral structure is formed by the polysilane, so that the surface of the reinforced fiber is coated with the spiral polysilane, the capability of absorbing external acting force of the reinforced fiber is enhanced, and the ductility of the concrete is improved.
本发明公开了一种具有延展性的高强混凝土及其制备方法，涉及建筑材料技术领域，主要应用于薄型叠合楼板方面，该高强度混凝土包括如下重量份原料：水200‑250份、水泥460‑480份、砂子480‑500份、废旧混凝土500‑520份、石子750‑780份和强化纤维60‑80份；强化纤维在受到外力作用时螺旋结构能够阻止裂纹的纵向传播，同时玄武岩基体能够避免表面螺旋结构出现层间剪切破坏，进而吸收更多的作用力，表面的聚硅烷的侧链含有碳氧双键以及长链烷基，碳氧双键与长链烷基上的氢相互作用，导致聚硅烷形成螺旋结构，使得强化纤维表面包覆螺旋状的聚硅烷，增强了强化纤维吸收外部作用力的能力，提升了混凝土的延展性。
