Sand-stone terrazzo

Abstract

The invention provides sand-stone terrazzo. The sand-stone terrazzo is prepared from the following raw materials in parts by weight: 300 parts of cement, 2-3 parts of sand and stones, 1.2 parts of glass granules, 1.5 parts of silica sand, 1.2 parts of shell granules, 7 parts of strength strengthening agent, 4 parts of polymer binder and water, wherein the grain size of the sand and stones is 5mm to 10mm, the glass granules are made from common glass through crushing and have the grain size of 3mm to 5mm, the silica sand has the grain size of 1.5mm to 3mm, granules of the silica sand are elliptical, the shell granules are made from shells through crushing and have the grain size of 1mm to 3mm, and the weight ratio of the water to the concrete is (1: 0.27) to (1: 0.33). According to the sand-stone terrazzo provided by the invention, the voidage generated during forming is low, the strength is high, and the dirt-removing power is improved; and due to the introduced polymer binder, the terrazzo has certain flexibility, is good in resistance to deformation and has relatively good freezing resistance.

Description

technical field [0001] The invention relates to the field of terrazzo and terrazzo floors, in particular to a sandstone terrazzo. Background technique [0002] Terrazzo (also known as terrazzo) is a product made by mixing gravel, glass, quartz stone and other aggregates into cement binder to make a concrete product, and then surface ground and polished. The terrazzo made of cement binder is called inorganic terrazzo, and the terrazzo made of epoxy binder is also called epoxy terrazzo or organic terrazzo. According to the construction process, terrazzo is divided into on-site pouring terrazzo and prefabricated plate terrazzo floor . [0003] Traditional terrazzo has a huge market in China due to its unique advantages such as low cost, optional color mosaic, and convenient construction. There are as many as one billion square meters of terrazzo floors used in various buildings in urban and rural areas across the country. However, the traditional construction technology makes...

Problems solved by technology

However, the traditional construction technology makes the terrazzo floor very rough and filthy, even before it is put into use, it is already filthy, which also brings serious obstacles to daily sanitation and cleaning

However, with the passage of time, very prominent problems have been encountered in actual use: stains, dull
