Abstract

The invention discloses a stone texture imitating permeable concrete prefabricated brick. The stone texture imitating permeable concrete prefabricated brick consists of two parts of a permeable main body layer and a stone texture imitating permeable surface layer from bottom to top, wherein the permeable main body layer is made from the following raw materials, in mixing proportion by weight of concrete per cubic meter: (a) macadams which are used as aggregates, with the addition amount of 1400kg / m<3>~1550kg / m<3>; (b) 310kg / m<3>~350kg / m<3> of cement; (c) 3.0kg / m<3>~3.5kg / m<3> of water reducing agents; (d) 25kg / m<3>~35kg / m<3> of fly ash. The stone texture imitating permeable concrete prefabricated brick provided by the invention has a permeable function, and at the same time, the surface of the stone texture imitating permeable concrete prefabricated brick has a decoration effect similar to that of natural stones; the stone texture imitating permeable concrete prefabricated brick integrates with environment, and the natural quality of cities is enhanced, so that the relationship between human beings and nature is closer. Moreover, the design of an optimized mixing proportion ensures the water permeability, the wear resistance and the physical mechanics index of the stone texture imitating permeable concrete prefabricated brick.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a stone-like texture permeable concrete prefabricated brick and a preparation method thereof. Background technique [0002] The surface of the city is gradually covered by impermeable materials, and the loss of rainwater resources is serious. At the same time, with the acceleration of urbanization and the rapid development of industrialization, the problem of water shortage is becoming increasingly serious. At present, there are a variety of permeable pavement products on the market, but their surface effect is single and the decorative effect is not good. As a permeable pavement with decorative functions, imitation stone texture permeable concrete satisfies the integration of decoration and water permeability. demand. [0003] The construction of permeable concrete with imitation stone texture mainly includes two methods: in-situ pouring and prefabricated brick pavi...
