Polymer modified ultra-high performance concrete with high interface bonding strength
The invention discloses polymer modified ultra-high performance concrete with high interface bonding strength. The polymer modified ultra-high performance concrete comprises the following components in parts by weight: 572-728 parts of cement; 52 to 130 parts of silica fume; 260 to 338 parts of limestone powder; 954 to 1032 parts of river sand; 156 to 234 parts of steel fiber; 2.6 to 10.4 parts of a composite polymer modifier; 8.32 to 9.88 parts of a water reducing agent; 202 to 208 parts of water; wherein the composite polymer modifier is prepared by compounding and uniformly mixing redispersible latex powder and hydroxypropyl methyl cellulose ether according to a mass ratio of 9: 1. The ultra-high performance concrete is high in breaking strength and tensile strength, and the bonding strength of new and old concrete interface areas is improved after the ultra-high performance concrete is used.
本发明公开了一种高界面粘结强度的聚合物改性超高性能混凝土，包括以下重量份的组分：水泥572‑728份；硅灰52‑130份；石灰石粉260‑338份；河砂954‑1032份；钢纤维156‑234份；复合聚合物改性剂2.6‑10.4份；减水剂8.32‑9.88份；水202‑208份；其中：复合聚合物改性剂：由可再分散乳胶粉和羟丙基甲基纤维素醚按质量比9:1复合并混合均匀制得。该超高性能混凝土抗折强度及抗拉强度高，使用后改善新老混凝土界面区域的粘结强度。
