Molded modified ornamental concrete precast T-cast stone and production method

Abstract

The invention discloses a molded modified ornamental concrete precast T-cast stone and a production method. The T-cast stone is precast through a premix injection or casting compaction process in a 3D engraved digital and is prepared from the following raw materials: cement, fiber, a polymer, silica fume, ultra-fine fly ash and an additive, wherein high-strength Portland cement which is more than 87% in whiteness is a major binding material; the T-cast stone is uniform in texture, application-level strength can reach 160MPa and breaking strength can reach 30MPa, and the T-cast stone is firm and durable, and free from cracking and dregs; the T-cast stone is excellent in plasticity and expressive force and is abundant in modeling ability through fine aggregate and antioxidant pigment as well as the digital mode; through innovative application of a 3D digital engraving machine on the mode, the product is strong in plasticity and diverse in shape; the product, with addition of the aggregate and the pigment, is equal in inside and outside and is stable in color after being maintained for 48 hours in a maintenance room at 80 DEG C after being precast, and the product is widely applicable to municipal landscape, city street and building facade decoration. The T-cast stone realizes effective utilization of mineral tailing and is environment-friendly.

Description

technical field [0001] The invention relates to the international patent classification C04B26 / 00 composition technology of mortar, concrete or artificial stone containing only organic binder, especially molded modified decorative concrete precast Tyco stone and its production method. Background technique [0002] Tyco stone is a synthetic modified decorative concrete material, usually refers to artificial stone solid surface material, artificial quartz stone, artificial granite, microcrystalline stone, cast stone, etc. According to the different production processes, it can be divided into four types: polyester artificial marble, composite artificial marble, silicate artificial marble, and sintered artificial marble. Different types of artificial stone have different components. The main components are resin, aluminum powder, pigment and curing agent. According to the different binders used, they can be divided into organic artificial stone and inorganic artificial stone. ...

Problems solved by technology

[0003] For example, the texture of natural marble is very beautiful, hard texture, good scratch resistance, wear resistance can also; but there are pores, easy to accumulate oil dirt, and natural marble The brittleness makes it impossible to make a countertop with a width of more than 1 meter. Two pieces of marble cannot be spliced ​​together, and bacteria are easy to breed in the gaps. Natural stone is dense and needs strong cabinet support. Cracks, difficult to repair, some invisible natural cracks, will break when the temperature changes drastically
