Embodiment 1

[0026] A method for producing special-shaped terrazzo using UHPC as a binding material, including the following steps:

[0027] 1. Preparation of UHPC bonding material: According to the UHPC manual, add water to UHPC and stir to prepare UHPC bonding material; the actual amount of water added in UHPC is determined according to the water consumption listed in the manual and the characteristics of the prepared terrazzo; terrazzo strength When the requirements are high, use the water consumption according to the instructions; when the terrazzo has a complicated shape and good fluidity of the bonding material is required, the water consumption can be increased by no more than 10% on the basis of the water consumption in the instructions.

[0028] The preparation of UHPC bonding material specifically includes the following steps: slowly add water to UHPC, the slow mixing time is not less than 3min, the slow mixing speed is 30r / min, until the material initially appears fluidity; then the f...

Abstract

The invention discloses a production method taking UHPC (Ultra High Performance Concrete) as a binding material for special-shaped waterstone. The production method comprises the following steps: I, preparing the UHPC binding material; II, preparing a mold; and III, pasting and pouring an aggregate. The performance advantages of high strength and excellent durability, weather fastness and mobilityof UHPC are fully utilized in combination with a special aggregate distribution and fixation method, so that one-time casting molding of the special-shaped waterstone through the mold comes true, thetypes of waterstone products are greatly enriched, and the unit area of waterstone can be increased. The special shape comprises but not limited to a single-curved surface, a double-curved surface and a broken line. Meanwhile, the surface grinding depth of waterstone is reduced, and the discharge of wastewater and slag is reduced.

Description

Technical field [0001] The invention relates to a terrazzo, in particular to a production method of a special-shaped terrazzo using UHPC as a binding material. Background technique [0002] Terrazzo (also known as grindstone) is a product made by mixing aggregates such as crushed stone, glass, quartz stone, etc. into cement binder or epoxy binder to make concrete products and then surface grinding and polishing products. With the development of material technology, more and more high-quality terrazzo is used in high-end decoration projects, and terrazzo shows a trend of rebirth. However, due to deficiencies in craftsmanship and materials, designers are quite restricted in their use. [0003] Terrazzo materials can be divided into cementitious materials and decorative aggregates. Cementitious materials refer to materials that bond aggregates and provide strength in terrazzo, and are widely used as ordinary Portland cement, sulphoaluminate cement and active or inactive powder admix...
