Problems solved by technology

From the perspective of the components that make up this kind of block, it uses water glass as a binder, and water glass, that is, sodium silicate, contains free alkali, which can react with carbon dioxide in the air to form sodium carbonate, and precipitate The white solid crystallizes and deteriorates the water glass, so the use of water glass as a binder brings certain difficulties to the on-site operation
From another point of view, the quality of building blocks, especially those used on non-load-bearing walls, is a very important issue, because light weight can save raw materials, and at the same time it is convenient for masonry, and It can reduce the burden on the building, and in order to obtain light blocks, the simplest and most applicable way is to form many tiny voids inside the blocks, and these voids can also play a role in heat preservation to a certain extent, but, No foaming material is given in the block composition proposed in this patent, so the mass of the block is relatively large

Embodiment 1

[0013] When making this kind of building blocks, first add about 15Kg of water to the mixer or container, and then add 2Kg of polyvinyl alcohol aqueous solution with a content of 10%-15% to it, and dilute the polyvinyl alcohol aqueous solution. Then add 15Kg of perlite to the container, so that the surface of the perlite can form a polyvinyl alcohol protective film, then add 65Kg of fly ash and 100Kg of cement, and 2Kg of a liquid mixture containing 1.2%--2% of gelatin and rosin And weight is 30% caustic soda of gelatin weight, and make the weight ratio between the gelatin in this liquid mixture and rosin be: 1: 0.8, after the material that adds is mixed evenly, mold is loaded, after demolding is building blocks.

Embodiment 2

[0015] Make building block according to the method for embodiment 1, wherein, the polyvinyl alcohol add-on of equal content is 3.5Kg, and perlite is 23Kg, and fly ash is 70Kg and cement 83Kg, the liquid mixture 1Kg of the gelatin of equal content and rosin And weight is 10% caustic soda of gelatin weight, and make the weight ratio between the gelatin and rosin in this liquid mixture be: 1:1.

Embodiment 3

[0017] Make building block according to the method for embodiment 1, wherein, the polyvinyl alcohol add-on of equal content is 1Kg, and perlite is 12Kg, and fly ash is 56Kg and cement 110Kg, the liquid mixture 3.5Kg of the gelatin of equal content and rosin , and make the weight ratio between the gelatin and the rosin in the liquid mixture be: 1: 1.5.

Abstract

A composition for making the building blocks contains cement, powdered coal ash (at least 30%), pearlite, adhesive and foaming agent. A method for making said building blocks includes such steps as sequential mixing, stirring, moulding and demoulding.

Description

Technical field: [0001] The present invention relates to a composition for making building blocks and a method of making building blocks from the composition. Background technique: [0002] Fly ash is a kind of waste discharged after coal combustion. Its stacking not only occupies land, but also pollutes the surrounding environment. In the field of construction, fly ash is usually used to make hollow blocks for masonry walls to realize waste utilization. For example, the name of the Chinese patent No. 1176039 authorized announcement is "a kind of lightweight brick" which provides a kind of brick using pulverized coal. An example of a hollow block made of ash. The lightweight brick proposed by this patent is composed of 50-68 parts of cement, 20-40 parts of fly ash, 10-15 parts of perlite and 2-4 parts of water glass. From the perspective of the components that make up this kind of block, it uses water glass as a binder, and water glass, that is, sodium silicate, contains f...
