Abstract

The invention relates to a concrete material, in particular to a super-high performance concrete decorative plate and a preparation method thereof. The super-high performance concrete decorative plateis prepared from the following raw materials in parts by weight: cementitious materials, aggregates, auxiliaries, water, and fibers; the auxiliaries are prepared from at least the following components in parts by weight: 60 to 100 parts of additives, 0.5 to 20 parts of pigments, 0.01 to 0.1 part of wetting and dispersing agent, and 0.3 to 0.8 part of stabilizer; and the cementitious materials areprepared from at least 600 to 900 parts of cement in parts by weight. According to the super-high performance concrete decorative plate, the use of the wetting and dispersing agent effectively improves a dispersion state of the pigments in liquid, ensures stable dispersion of the pigments, and avoids a phenomenon of uneven mixing. Meanwhile, the stabilizer can enable the dispersed inorganic pigments to be uniformly and stably suspended in UHPC slurry, and in particular to be stably suspended in high-flow UHPC slurry, even if bleeding phenomenon occurs accidentally in a forming process of theslurry, the phenomena of floating color and dazzling of the pigments and the like are not generated.

Description

technical field [0001] The invention relates to concrete materials, in particular to an ultra-high performance concrete decorative board and a preparation method thereof. Background technique [0002] Ultra-high-performance concrete (hereinafter referred to as UHPC) has ultra-high mechanical strength and excellent weather resistance, and has become the most innovative cement-based engineering material in the past three decades. Using UHPC for exterior wall decoration can greatly improve the "coating" of buildings. "The lifespan of the building is the same as that of the building. At present, few or no enterprises in China use UHPC as building exterior wall hanging panels, but many large foreign companies such as Lafarge in France and Taktl in the United States have carried out decorative applications of UHPC, among which Taktl has realized UHPC automated production and successful commercial application. UHPC as building exterior wall decoration can make up for many shortco...
