Abstract
The present invention relates to a colorful footpath board which adopts fly ash as main material. Fly ash and white ash can be used as a base layer, and sand, white cement, white ash and colorful powder can be used as surface layer material. The base layer and the surface layer material are respectively added in a mould according to definite thickness, and the present invention can be obtained by pressing. The present invention is a fly ash comprehensive utilization method which is easy to popularize, and the strength of the manufactured footpath boards of different colors can highly reach 20MPa. The present invention is a new product for beautifying environment and decorating townscape, and the price is low.
Description
The present invention relates to utilization of coal ash, a kind of more precisely colour boardwalk of using with flyash manufacturing road sidewalk, city.
Colour boardwalk is a kind of cross walk of urban construction road both sides and constructional materials that terrace is built by laying bricks or stones of being used for, and it can be beautified the environment, and decorates the appearance of the city, is paid attention to by people more and more.In recent years, what China only had that minority factory produces is primary raw material with cement, the grey boardwalk that is pressed into by the ordinary concrete prescription.Such product color is single, and cost is than higher.
The purpose of this invention is to provide a kind of is primary raw material and colour boardwalk with low cost with flyash.
Realize main technical schemes of the present invention; Be to be basic unit material and to be capstock and with the boardwalk of certain thickness formation with sand, white cement, lime, toner, compound with flyash and lime compound.
The concrete structure of boardwalk of the present invention and its used material quantity (in volume ratio):
Basic unit material: comprise (A) flyash and (B) be selected from lime, cement, lime and gypsum, lime and cement any, lime preferably, its mixing ratio (A): (B) be 50-70: 30-50, the mixing ratio of described lime and gypsum is 80-90: 10-20, the mixing ratio of described lime and cement is 80-90: 10-20, the mixing ratio sand of capstock: white cement: lime: toner=30-40; 25-30: 28-42: 1.
Described flyash is steam power station flyash, and the lime-ash hardness in the flyash is little, rolls promptly through edge runner to meet the requirements, and the purpose that rolls is the activity that excites flyash.
Described lime meets the standard of GB1594-97 regulation III level quicklime.
Described toner is commercially available natural minerals, uses not fugitive color of this material.Can select the toner of different colours as required or allocate.
Boardwalk preparation method of the present invention: (1) will mix basic unit material and pour in the mould, pour the capstock that mixes after smooth again into above basic unit's material, use harder compression moulding; (2) demoulding, watering keeps it moistening, and natural curing is 28 days under the normal temperature, also can utilize power plant's waste gas to adopt steam kiln or autoclave steam maintenance.
The boardwalk that according to said method makes, during its thickness 50mm, the material thickness 42 ± 2mm of basic unit, capstock 8 ± 2mm; During its thickness 100mm, the material thickness 92 ± 2mm of basic unit, capstock thickness 8 ± 2mm.
The shape of described boardwalk comprises hexagon, link formation, square type, and anti-skidding lines decorative pattern can also be delineated in the surface.
Used harder, mixer, the crushing mill of the present invention all is the plant equipment of using always.
Major advantage of the present invention and effect: boardwalk of the present invention is owing to contain 50% above flyash, relevant " utilization of three wastes " preferential policy of national regulation in addition, so the economic benefit of this product is very remarkable; Product strength according to method preparation of the present invention reaches 10-15MPa, reaches as high as 20.0MPa;
The present invention is a total utilization of PCA approach that is easy to promote, and for beautifying the environment, decorates the appearance of the city a kind of new product is provided, and has social benefit significantly.
Further set forth characteristics of the present invention with example below.
Example 1
5.5M is expected in basic unit
3Flyash, 4.5M
3Lime mixes and pours in the mould of rectangle, pours the capstock that has mixed: 3.2M more upward into after smooth
3Sand, 2.6M
3White cement, 2.8M
3Lime, 0.1M
3The white powder is used press compression moulding, and demoulding is sprinkled water 3 every day then, and to keep its moisture state, maintenance promptly obtains the product of groundwork thickness 42mm, surface thickness 8mm after 28 days, and after testing: this product strength is 16MPa.
Example 2
Experimentation is with example 1, used raw material: flyash 5.5M
3, lime 3.8M
3, cement 1.7M
3, sand 3.8M
3, white cement 2.8M
3, lime 4.0M
3, yellow powder 0.1M
3Groundwork thickness 42mm, surface thickness 8mm.The intensity of product is 18MPa.
