Novel lightweight ultrahigh-strength concrete and preparation method thereof
The invention relates to the technical field of building materials, and discloses novel lightweight ultrahigh-strength concrete and a preparation method thereof.The novel lightweight ultrahigh-strength concrete is prepared from, by mass, 600-650 parts of cement, 123-336 parts of silica fume, 118 parts of glass beads, 229-336 parts of glass powder, 118 parts of steel fibers, 50-60 parts of a water reducing agent and 146-176 parts of water. The lightweight high-strength hollow glass beads are used as the lightweight micro aggregate, and meanwhile, the hollow glass beads, the glass powder and the silica fume with different particle sizes are adopted to fill a cementing material system step by step, so that the gradation is good, the internal structure is very compact, and the compressive strength reaches 117-126 MPa after 28 days. Meanwhile, the novel light ultrahigh-strength concrete provided by the invention can be prepared under natural curing, and compared with the traditional ultrahigh-strength concrete which needs steam high-temperature curing or high-temperature water curing, the novel light ultrahigh-strength concrete provided by the invention has the advantages that the curing difficulty and the curing cost are reduced, and the practical engineering application is facilitated.
本发明涉及建筑材料技术领域，公开了一种新型轻质超高强混凝土及其制备方法，所述新型轻质超高强混凝土，以质量分数计，其原料包括：水泥600‑650份、微硅粉123‑336份、玻璃微珠118份、玻璃粉229‑336份、钢纤维118份、减水剂50‑60份、水146‑176份。本发明以轻质高强空心玻璃微珠作为轻质微集料，同时采用粒径不同空心玻璃微珠、玻璃粉、微硅粉对胶凝材料体系进行逐级填充，级配良好，内部结构非常密实，28天抗压强度达到117‑126MPa。同时，本发明提供的新型轻质超高强混凝土可在自然养护下制成，相较于传统的超高强混凝土需要蒸汽高温养护或高温水养，降低了养护难度和养护成本，便于实际工程应用。
