Ultra-high performance concrete joint mixture
The invention belongs to the technical field of building materials, and discloses an ultra-high performance concrete joint mixture. The ultrahigh-performance concrete joint mixture comprises the following components in parts by weight: 100 parts of a cementing material, 90-120 parts of sand, 5-8 parts of an expanding agent, 0.08-0.2 part of cellulose ether, 0.15-0.25 part of a defoaming agent, 1-3parts of a water reducing agent, 16-19 parts of water and 0-2.5 parts of redispersible latex powder. The joint mixture further comprises PVA (Polyvinyl Acetate) fibers. The joint mixture provided bythe invention has ultrahigh strength and durability, has higher binding power and crack resistance, and is suitable for joint filling of ultra-high performance concrete products.
本发明属于建筑材料技术领域，公开了一种超高性能混凝土填缝剂。所述超高性能混凝土填缝剂，包括以下按重量份数计的组分：胶凝材料100份，砂90～120份，膨胀剂5～8份，纤维素醚0.08～0.2份，消泡剂0.15～0.25份，减水剂1～3份，水16～19份，可再分散性乳胶粉0～2.5份。所述填缝剂还包括PVA纤维。本发明的填缝剂具有超高强度和耐久性，并具有较高的粘结力和抗裂性，适用于超高性能混凝土制品的拼缝填充。
