High-grade low-carbon ultra-high-performance self-compacting concrete containing coarse aggregate
The invention relates to the technical field of building materials, and particularly discloses high-grade low-carbon ultra-high-performance self-compacting concrete containing coarse aggregate. The high-grade low-carbon ultra-high-performance self-compacting concrete containing the coarse aggregate comprises the following components in parts by mass: 100 parts of water; 185 to 187 parts of cement; 30 to 32 parts of fly ash; 15 to 16 parts of phosphorus slag; 370 to 375 parts of fine aggregate; 730 to 750 parts of modified recycled coarse aggregate; 70-75 parts of an inorganic whisker filler; 6.2 to 6.6 parts of an additive; the modified recycled coarse aggregate is prepared by soaking and modifying recycled coarse aggregate in a modifying solution; the modified liquid is a compound of water, mercaptoacetic acid, octadecyl trimethyl ammonium chloride and oleamide propyl amine oxide. The method has the advantage of better improving the strength of the concrete doped with a large amount of recycled aggregate.
本发明涉及建筑材料技术领域，具体公开了一种含粗骨料的高标号低碳型超高性能自密实混凝土。含粗骨料的高标号低碳型超高性能自密实混凝土包括以下质量份数的组分：水100份；水泥185‑187份；粉煤灰30‑32份；磷渣15‑16份；细骨料370‑375份；改性再生粗骨料730‑750份；无机晶须填料70‑75份；外加剂6.2‑6.6份；改性再生粗骨料由再生粗骨料在改性液中浸泡改性制得；改性液为水、巯基乙酸、十八烷基三甲基氯化铵、油酸酰胺丙基氧化胺的复配。本发明具有更好地提高大量掺用再生骨料的混凝土的强度的优点。
