Description
The invention provides and a kind ofly catch and settled flyash is raw material, is equipped with aggregate and activator,, belong to material of construction through steam-cured load-bearing holllow building block proportioning and the manufacture craft that forms of water mix moulding to receive in the thermal power plant boiler flue.
Utilize flyash to make building block, the documents and materials record is more, has to make agglutinate, cinder or flyash haydite with lime, gypsum and make aggregate, is mixed in proportion processing, vibratory compaction, the steam-cured fly ash silicate small-sized hollow building block that forms; Also have with flyash and cinder and make major ingredient, cement is the hollow brick that agglutinate is made; And be major ingredient with flyash, bonding clay, fusing assistant, binding agent add compression moulding behind the water, the flyash face brick of high-temperature firing finished product.These building blocks for utilizing the flyash waste material, are turned waste into wealth, and avoid ruining ground, solve the sand source and play good effect.But these fly ash building blocks not load-bearing can't be in order to build the bearing wall of buildings by laying bricks or stones.
The invention provides that a kind of making promptly is incubated and the proportioning raw materials of the fly ash building block of load-bearing and building block manufacture craft.
The proportioning raw materials of load-bearing holllow building block part by weight is as follows:
Flyash 27-32 part, levigate, cross 4900 hole sizers/1 square inch
Aggregate (slag or volcanic cinder) 45-51 part
Activator 19-21 part
Water 3-3.5 part.
Here, part is as follows by weight for the activator proportioning:
50 parts of slag (matured slag) or volcanic cinder
2 parts of dihydrate gypsums
Unslaked lime (calcium content is high more good more) 35-40 part
All material all will be worn into the identical fineness of cement in the activator, promptly by 4900 hole sizers/1 square inch.
Load-bearing holllow building block manufacture craft provided by the invention is as follows:
1, add water after by proportioning the each component raw material being mixed, wherein flyash is by 4900 hole sizers/1 square inch;
2, putting into forced stirrer stirred 3-8 minute;
3, put into the brick press moulding of vibrating;
4, shaping building block is put in the steam kiln and was cleared up naturally 4-6 hour, and the kiln temperature is 20-25 ℃ when going into kiln, is incremented to 30-40 ℃;
5, clear up after, the kiln temperature by per hour 5 ℃ rise progressively, until 50 ℃, then per hour by 10 ℃ of risings, during to 92-98 ℃ till.This temperature maintenance 6-8 hour, cooling naturally then, kiln discharge, vapor cure time meter 24 hours.
By proportioning raw materials provided by the invention and building block manufacture craft, No. 90, the minimum label of its building block load-bearing is suitably adjusted volcanic ash aggregate content and other component, also can be made into label and be No. 200 load bearing hollow brick.This building block heat transfer coefficient is 1/3rd of a clay brick, builds the body of wall of same thickness by laying bricks or stones, as the 370mm wall, can reduce thermal losses 30-40%.Areas of Shenyang is in heating phase, every square metre of dwelling house, and coal 9.25kg capable of saving fuel, the unit weight of load-bearing holllow building block are 2/3rds of clay brick.
