High-strength self-compacting concrete and preparation method thereof
The invention discloses high-strength self-compacting concrete and a preparation method thereof, and relates to the technical field of high-strength concrete. The concrete is prepared from the following components in parts by weight: 90 to 120 parts of cement, 10 to 40 parts of phosphorus slag powder, 200 to 400 parts of coarse aggregate, 60 to 80 parts of fly ash microspheres, 750 to 800 parts of machine-made sand, 5 to 12 parts of glass powder, 5 to 20 parts of modified lignin fiber, 4 to 15 parts of silicon dioxide aerogel, 5 to 10 parts of water reducing agent and 100 to 200 parts of water. The invention also provides a preparation method of the concrete. The fly ash microspheres, the glass powder, the modified lignin fibers and the like are added into the concrete, so that the cement consumption is reduced, the concrete with relatively high comprehensive performance is obtained, and the problems of relatively high cement consumption, insufficient strength, easiness in cracking and the like in the prior art are effectively solved.
本发明公开了一种高强度自密实混凝土及其制备方法，涉及高强度混凝土技术领域；该混凝土包括以下重量份组分：水泥90‑120份、磷渣粉10‑40份、粗骨料200‑400份、粉煤灰微球60‑80份、机制砂750‑800份、玻璃粉5‑12份、改性木质素纤维5‑20份、二氧化硅气凝胶4‑15份、减水剂5‑10份和水100‑200份。本发明还提供了上述混凝土的制备方法。本发明在混凝土中加入粉煤灰微球、玻璃粉和改性木质素纤维等，减少水泥用量，得到了综合性能较强的混凝土，有效解决了现有技术中水泥用量较高、强度不足和易开裂等问题。
