Natural tuff ultra-high performance concrete and preparation method thereof
The invention discloses a natural tuff ultra-high performance concrete and a preparation method thereof. The concrete is prepared from the following components in parts by weight: 100 to 250 parts ofnatural tuff, 100 to 250 parts of limestone powder, 600 to 900 parts of cement, 100 to 200 parts of silica fume, 900 to 1200 parts of fine aggregate, 120 to 200 parts of steel fibers, 8 to 10 parts ofan additive and 160 to 190 parts of water. Based on the characteristics of the chemical components of natural tuff, the mineral additives activate each other through fine grinding; the activity of natural tuff is fully utilized to form a new ultra-high performance concrete cementing material system, the wastes are fully utilized, meanwhile, the strength and the volume stability of the ultra-highperformance concrete are improved, the raw material source of the ultra-high performance concrete is broadened, the cost of the ultra-high performance concrete is reduced, and the promotion and the application of the ultra-high performance concrete are easily achieved.
本发明公开一种天然凝灰岩超高性能混凝土及其制备方法，包括以下重量份的组分：天然凝灰岩100～250份、石灰石粉100～250份、水泥600～900份、硅灰100～200份、细骨料900～1200份、钢纤维120～200份、外加剂8～10份和水160～190份。本发明结合天然凝灰岩的化学组分特点，采用磨细手段进行矿物掺合料互相激发的理论，充分的利用天然凝灰岩的活性，形成新的超高性能混凝土胶凝材料体系，不仅实现了废弃资源的充分利用，同时也提高了超高性能混凝土的强度和体积稳定性，拓宽了超高性能混凝土的原材料来源，降低超高性能混凝土的成本，更加有利于超高性能混凝土的推广和应用。
