Abstract
The invention provides a grouting material for a wall partition board, and the grouting material comprises a cementitious material, an expansion component, an early strength component, a water reducing component, a thickening and water retention component, an aggregate and an enhanced bonding component. The grouting material is prepared from a high strength material as the aggregate and cement as a base material by supplementing high flow, micro expansion, anti segregation and other materials, is free of iron ions and chloride salts, and has the advantages of early strength, high strength, strong adhesion, micro expansion, good fluidity, no corrosion, impact resistance and vibration resistance. Slurry can flow automatically. The grouting material can automatically pour a narrow gap under the condition of no vibrating and ramming, and is suitable for pouring and grouting of narrow gaps of the upper and the lower end of the wall partition board. The grouting material can ensure the reliable and flexible connection between the upper end and the lower end of a lightweight wall partition board and a floor board.
Description
technical field [0001] The invention belongs to the technical field of building materials, in particular to a grouting material for partition boards. Background technique [0002] Partition wall panel refers to the wall prefabricated panel used for the internal partition wall of the building specified in JG / T169-2005 "Lightweight Panel for Building Partition Wall". The partition panel includes glass fiber reinforced cement panel, glass fiber reinforced Gypsum hollow slats, steel wire (steel mesh) reinforced cement slats, light concrete slats, composite sandwich lightweight slats, etc. The full name is lightweight slats for building partition walls, which are used as the main material for non-load-bearing inner partition walls in general industrial buildings, residential buildings, and public construction projects. [0003] Projects that use lightweight partition wall slats as non-load-bearing inner partition walls for general industrial buildings, residential buildings, and...
