Abstract

The invention discloses a concrete building block with stable quality. The concrete building block comprises, by weight, 160-180 parts of cement, 6-12 parts of waste calcining material, 4-8 parts of shale powder and 30-50 parts of gravel, 6-12 parts of light calcium carbonate, 8-16 parts of nylon fiber, 10-18 parts of degasifier, 3-5 parts of sodium carbonate, 3-5 parts of organosilicone waterproofing agent and 6-12 parts of rosin compound. The rosin compound is prepared by the following process that 4-tert-octylphenol, oxalic acid and formaldehyde are mixed for heating, stirring and dehydrating under vacuum, the temperature is raised, rosin is added, then the temperature is maintained, pentaerythritol is added for stirring, and the mixture is cooled to obtain the rosin compound. The concrete building block has the advantages of low price, high strength, long-term durability, environmental protection and no pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a concrete block with stable quality. Background technique [0002] Concrete is an important basic building material, its usage is huge, and its performance needs to meet certain standards before it can be safely used in the corresponding environment. The concrete raw materials currently on the market are unevenly mixed, and the quality of the blocks is unstable. Once exposed to wind and sun, there is a risk of collapse and loss. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a concrete block with stable quality, low price, high strength, long durability, green and environmental protection, and no pollution to the environment. [0004] A kind of concrete block with stable quality proposed by the present invention, its raw material comprises by weight: 160-180 parts of cement, 6-12 parts of waste ...
