A low color difference concrete

Abstract

The invention discloses low-chromatic aberration concrete. The low-chromatic aberration concrete is characterized by containing the following components in parts by weight: 160-240 parts of cement, 50-80 parts of mineral powder, 70-120 parts of coal ash, 1000-1100 parts of stones, 90-180 parts of sand, 300-400 parts of water, 20-30 parts of a film foaming agent, 8-14 parts of a water reducer and 2-4 parts of CTF concrete synergist. The low-chromatic aberration concrete has the characteristics of easiness in dirt removal and good over-vibration adaptability.

Description

technical field [0001] The invention relates to a kind of concrete for building, especially a kind of low color difference concrete. Background technique [0002] Concrete refers to an engineering composite material in which the aggregate is cemented into a whole by a cementitious material. The gelatinous material is generally cement, and the aggregate is usually sand and gravel. With the development of the economy, various infrastructure projects have sprung up, and the consumption of concrete has also increased sharply. For ordinary buildings, after the concrete pouring is completed, the surface needs to be decorated with ceramic tiles and other decorative materials. However, in some basic projects, such as traffic tunnels, fair-faced concrete is usually used as the exterior surface directly, that is, no decorative materials are attached. However, in actual construction, color differences often appear on the concrete surface, which greatly reduces its aesthetics. The re...
