Abstract

The invention discloses an evenly dispersed concrete building block, which comprises the following raw materials in parts by weight: 120 to 140 parts of cement, 40 to 50 parts of moulding promoter, 2to 6 parts of iron powder, 1 to 3 parts of potassium carbonate, 2 to 5 parts of polyoxyethylene nonyl phenyl ether, 1 to 3 parts of organic silicon waterproof agent, and 2 to 8 parts of rosin compound. The rosin compound is prepared by the following steps: mixing hydroquinone, critic acid, and formaldehyde; heating the mixture under stirring, carrying out vacuum dehydration, heating, adding rosin,maintaining the temperature, then adding polyethylene glycol, stirring, and cooling. The provided evenly dispersed concrete building block has the advantages of low price, high strength, durability,green, environmental friendliness, and pollution-free property.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a uniformly dispersed concrete block. Background technique [0002] There are many kinds of existing blocks, different blocks will have different methods in the transportation process and the processing of material bricks, and the properties of the produced blocks will also be different, but in these production processes There is often the problem of uneven mixing of raw materials in the process, which has an impact on the production efficiency of the block. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a uniformly dispersed concrete block, which is cheap, high in strength, durable, environmentally friendly, and has no pollution to the environment. [0004] A uniformly dispersed concrete block proposed by the present invention, its raw materials include by weight: 120-140 parts of cemen...
