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:
The present invention relates to a kind of be used to the make composition of building block and the method for making building block of said composition.
Background technology:
Flyash is a kind of waste material of being discharged behind the coal combustion, and it stacks not only land occupation, but also pollutes surrounding enviroment.Usually utilize flyash to make to be used for the holllow building block of masonry panel at building field, realizing utilization of waste material, be called " a kind of light cinder brick " as the name of No. 1176039 Granted publications of Chinese patent and just provide an a kind of example that utilizes flyash to make holllow building block.The light cinder brick that this patent proposed is to be that the cement of 50-68 part, the flyash of 20-40 part, the perlite of 10-15 part and the water glass of 2-4 part constitute by weight.From constituting the component of this kind building block, it adopts water glass as tackiness agent, and water glass is to contain free alkali matter in the water glass, can generate yellow soda ash with airborne two vaporized carbons reaction, and separate out white crystalline solid, make water glass rotten, so, adopt water glass to bring certain difficulty to execute-in-place as tackiness agent.From another aspect, because of building block, particularly be applied in the building block on the non-load bearing wall, the size of its quality is a very important problem, because of light weight can be saved starting material, also conveniently build by laying bricks or stones simultaneously, and can alleviate the buildings burden, and to seek out the building block of light weight, and the simplest suitable a kind of mode is to make that building block is inner to form many small spaces, these spaces can also be played the effect of insulation to a certain extent, but, do not provide foam material in the building block composition that this patent proposed, so the quality of this building block is relatively large.
Summary of the invention:
Task of the present invention provides a kind of composition that is used to make building block, and the building block light weight with said composition is made can also solve the utilization of waste material problem simultaneously.
Another task of the present invention provides a kind of method of making building block of said composition.
Proposed by the invention be used to make the material that composition that building block uses comprises following weight percent: cement 45%--60%, flyash 30%--45%, perlite 6%--12%, binding agent and whipping agent respectively account for 0.5%--2%, described binding agent is that the liquid pva of 10%--15% constitutes by content, and whipping agent is made of gelatin that contains 1.2%--2% and rosiny liquid form mixt, and makes gelatin and rosin weight ratio between the two in this liquid form mixt be: 1: 0.5-1.5.Wherein, tackiness agent can adopt water-soluble polymers, as polymkeric substance such as polyvinyl alcohol; Whipping agent can make and form many small spaces in the building block, can also play insulation when alleviating the building block quality, and increases effect such as its flexibility.Adding liquid pva in the mixture can make viscosity, anti-caking performance, the dispersive ability of composition increase; And rosin has fast viscosity of good low temperature and pressure-sensitive, especially can also play the effect of whipping agent at concrete; Gelatin is a lyophilic colloid, can play the effect of whipping agent at concrete.
Comprise also in the liquid form mixt of described whipping agent that weight is the caustic soda of the 10%--30% of gelatin weight.Add caustic soda in the mixture.
The material that comprises following weight percent in the described composition: cement 50%--60%, flyash 30%--40%, perlite 8%--10%, content are that 10%--15% polyvinyl alcohol water solution 0.8%-1.5%, content are that gelatin and the rosin mixed aqueous solution of 1.2%-1.5% is 0.5%-2%.
The method of making building block of above-mentioned composition may further comprise the steps:
Get polyvinyl alcohol water solution and put into container according to above-mentioned weight percent, in this container, add perlite, flyash and the cement of above-mentioned weight percent then more successively, the whipping agent that the even back of mixing of materials of being added is added described weight percent, with its back dress mould that stirs, treat to be building block after its demoulding.In this making method, at first add perlite, make perlitic surface energy form the polyvinyl alcohol protective membrane.
Describedly comprise that also adding volume in container is the step of 4-8 times of water of polyvinyl alcohol water solution before in container, adding polyvinyl alcohol water solution.
Proposed by the invention be used to make the building block composition and adopted at least 30% flyash, and flyash is trade waste, so the building block cost of making of said composition is lower; Simultaneously, rosin that adds in the said composition and gelatin can also play the effect of whipping agent in thickening and stable building block, make the building block of making have more small spaces, can reduce the quality of building block, and caustic soda can play the early strong effect of moisture absorption.
