Embodiment 1

[0034] This embodiment provides a UHPC imitation stone exterior wall hanging board in imitation gold linen style, see schematic figure 2 , the specific structure includes a first decorative layer 1, a second decorative layer 2 and a structural layer 3 which are sequentially laminated, and a glass fiber mesh cloth (not marked in the figure) is arranged between the second decorative layer 2 and the structural layer 3. The first decorative layer 1, the second decorative layer 2 and the structural layer 3 are UHPC mortar, the color RGB values ​​of the first decorative layer 1 and the second decorative layer 2 are different, and the part of the surface of the second decorative layer 2 is from the first decorative layer 1 surface exposed. UHPC mortar is a mixture composed of cement, active admixture, high-quality quartz sand aggregate, admixture and water. Yellow pigment is added to the first decorative layer 1, and part of the aggregate is replaced with bright black colored sand ...

Embodiment 2

[0047] This embodiment provides a UHPC imitation stone exterior wall hanging board with an imitation jute stone rust spot style, see schematic figure 2 , to include three layers from outside to inside: the first decorative layer 1, the second decorative layer 2 and the structural layer 3. The first decorative layer 1, the second decorative layer 2 and the structural layer 3 are all UHPC mortar, and the UHPC mortar is a mixture composed of cement, active admixture, high-quality quartz sand aggregate, admixture and water. Yellow pigment is added to the first decorative layer 1, gray pigment is added to the second decorative layer 2, and rust red colored sand is added to replace part of the aggregate, the color tone of the first decorative layer 1 and the second decorative layer 2 Inconsistent. In the UHPC imitation stone exterior wall hanging board in this embodiment, the thickness of the first decorative layer 1 is 3 mm, the thickness of the second decorative layer 2 is 5 mm,...

Embodiment 3

[0059] The difference between this embodiment and Embodiment 2 is that the surface of the structural layer 3 is partially exposed from the surface of the first decorative layer 1 to form heather gray, and the surface of the entire UHPC exterior wall panel presents the first decorative layer 1 and the second decorative layer 2. The appearance effect of lychee surface mixed with the three colors of structure layer 3.

[0060] In this embodiment, the preparation of the UHPC exterior wall hanging board of imitation jute stone rust spot stone style mainly includes the following steps:

[0061] Step 1: Stir the slurry of the first decorative layer 1, the second decorative layer 2 and the structural layer 3 according to the preparation, and select the UHPC aggregate of the first decorative layer 1 and the second decorative layer 2 with a particle size of 0.5mm Sand, the standard mortar fluidity of UHPC mixture is 330mm;

[0062] Among them, the weight ratio of each component of the ...

Abstract

The invention provides a UHPC stone-like outer wall hanging plate. The UHPC stone-like outer wall hanging plate comprises a first decorating layer, a second decorating layer and a structural layer which are sequentially arranged in a laminated mode, and are all made of UHPC mortar; the first decorating layer and the second decorating layer are different in color RGB value; and the surface of the second decorating layer is partially exposed out of the surface of the first decorating layer. The invention further provides a manufacturing process of the UHPC stone-like outer wall hanging plate. The manufacturing process comprises the following steps: S1, material blending is conducted; S2, first decorative layer slurry is poured; S3, second decorative layer slurry is poured; S4, structural layer slurry is poured and vibrated; S5, curing and forming is carried out; and S6, demolding is carried out, and treatment of one or a combination of two or more of shot blasting, chiseling, hammering,mincing and burning stripping is carried out. According to the technical scheme, the UHPA outer wall hanging plate adopts a double-decorative-layer structure form, inorganic pigments with different colors or different proportions are added, so that the tones of the two decorative layers are inconsistent, and various decorative effects can be provided for buildings.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a UHPC imitation stone external wall hanging board and a manufacturing process. Background technique [0002] Ultra-high performance concrete (hereinafter referred to as UHPC) has ultra-high mechanical strength and ultra-high durability, 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 " The lifespan of the "coat" should be the same as that of the building. At present, few or no enterprises in China use UHPC as building exterior wall cladding. [0003] In order to achieve ultra-high mechanical properties and ultra-high durability, in addition to using highly active admixtures such as silica fume and ultra-low water-cement ratio, UHPC hardly uses coarse aggregates, but uses aggregates with a particle size of less than 2.0mm. Quartz sand or even quartz p...
