Abstract

The invention discloses an antique brick and applications thereof. The antique brick comprises the following active ingredients in parts by weight: 100-200 parts of mineral powder, 20-50 parts of pulverized coal ash, 5-20 parts of excitant, 1-10 parts of iron oxide black, 250 parts of sand, 500 parts of stones and 25-39 parts of water. The antique brick has the properties of early strength, durability, permeability resistance, corrosion resistance, freezing and thawing resistance, low heat of hydration, good crack resistance, environment-friendliness and the like, and can replace cement products to be applied to restoration engineering of historic buildings.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular, the invention relates to an antique brick and its application. Background technique [0002] In recent years, cement products have been widely used in various fields of construction. However, due to the characteristics of cement in the restoration of ancient buildings, it is not suitable for application in the restoration of ancient buildings. The floor tiles and wall tiles in some ancient buildings have been eroded for many years. The damage was severe. This requires a new type of durable and environmentally friendly antique brick to replace and be used in ancient building restoration projects. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, an object of the present invention is to propose a kind of antique brick and its application, and this antiqu...
