Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a spray-coated ultra-high performance decorative concrete material and a preparation method thereof. Background technique

[0002] Ultra-high performance concrete (UHPC) has ultra-high mechanical properties and excellent durability. Using UHPC decorative panels instead of various coatings can greatly reduce the maintenance cost of buildings and improve the decorative effect of buildings. Therefore, it is more and more popular with the public.

[0003] Due to the improvement of the public's aesthetic level, various landmark buildings with complex curved surfaces are highly respected. At this stage, GRC materials are mainly used as exterior decorative panels, but their performance is poor, and they are prone to deformation and cracking, and their durability is not satisfactory. Requirements for the same lifespan as the building. However, ordinary UHPC materials are dif...
