QUICK-HARDENING MORTAR COMPOSITION FOR SLOPE SURFACE CONSTRUCTION AND QUICK-HARDENING MORTAR FOR SLOPE SURFACE CONSTRUCTION
To provide a quick-hardening mortar composition for constructing a slope surface, which has fluidity for easy pumping and filling without material separation in repairing or newly constructing a large section with a gradient, and can secure a slope and finish plastering after the filling.SOLUTION: A quick-hardening mortar composition for constructing a slope surface includes: a binder comprising cement, inorganic sulfate and calcium aluminate; a fine aggregate; a water reducing agent; and fibers. The water reducing agent contains at least one water reducing agent selected from the group consisting of a naphthalenesulfonic acid-based water reducing agent, a lignin sulfonic acid-based water reducing agent and a melamine-based water reducing agent. The content of the polycarboxylic acid-based water reducing agent is less than 0.08 pts.mass based on 100 pts.mass of the binder, and the content of the fine aggregate is 110-270 pts.mass based on 100 pts.mass of the binder.SELECTED DRAWING: None
【課題】材料分離せず、勾配を伴う大断面の補修や新設工事においても容易にポンプ圧送ができ、且つ充填できる流動性に加えて、充填後に勾配を確保し左官仕上げできる勾配面施工用速硬性モルタル組成物を提供すること。【解決手段】セメント、無機硫酸塩及びカルシウムアルミネート類からなる結合材と、細骨材と、減水剤と、繊維類とを含み、減水剤が、ナフタレンスルホン酸系減水剤、リグニンスルホン酸系減水剤及びメラミン系減水剤からなる群から選択される少なくとも一種の減水剤を含み、ポリカルボン酸系減水剤の含有量が、結合材１００質量部に対し、０．０８質量部未満であり、細骨材の含有量が、結合材１００質量部に対し、１１０〜２７０質量部である、勾配面施工用速硬性モルタル組成物。【選択図】なし
