Description
Technical field
The present invention relates to constructional materials, particularly, relate to permeable brick of a kind of ecological slag and preparation method thereof.
Background technology
At present, in China, be main resource with natural sandstone, can make permeable brick; This permeable brick is realized pervious function mainly through the slit between sand grains and the stone grain.But, at sleety weather, when this brick runs into muddy water,, reduce water permeability because the mud in the muddy water can block the slit between sand grains and the stone grain, influence road traffic.
In recent years, though China has obtained rapid progress aspect environmental improvement, compared with developed countries such as Northern Europe, Australia and New Zealands; Also there is a big difference; The dustiness of air is still bigger, also has sandstorm, the mud and sewage behind the sleet; The water-permeable passage that can make above-mentioned permeable brick loses pervious function fully in not enough year.
It is thus clear that the resistant of above-mentioned permeable brick and permeable problem still become and hinder the bottleneck that permeable brick is applied; And, be major ingredient with natural sandstone, need a large amount of gravels by nature of exploitation, be unfavorable for the protection of ecological environment.
Summary of the invention
The objective of the invention is to,, propose the permeable brick of a kind of ecological slag to the problems referred to above, with realize that stain resistance is strong, good water permeability, cost is low, the feature of environmental protection good and outward appearance is graceful advantage.

In the permeable brick of ecological slag of various embodiments of the present invention, after ecological slag (being slag or industrial melting waste slag) is calcined through pyrolytic semlting, C in its mineralogical composition
3S, C
2S and C
3A isoreactivity material has the hydraulic gelling; And particle surface is coarse; Internal construction self is covered with the hole of the spongy natural enclosing not of uniform size of picture, and these holes not only have the characteristics of suctions, good water permeability, and the anti-skidding noise that produces can also utilize surperficial small concavo-convex absorption vehicle ' the time.
Through repeatedly experiment, find that choosing particle diameter is that 2-8mm, volume are 70-80 parts ecological slag, and P.O42.5 cement is 350-400kg/m
3Can prepare the permeable brick of all ecological preferably slag of water permeability and endurance quality; Wherein, the optimum amount of cement with surface that can just package aggregate, to form a kind of uniform cement serous coat be appropriateness, and is principle to adopt minimum cement consumption; Because cement consumption too much can cause water permeability to descend, and cost increases; And in the preparation process of the permeable brick of ecological slag, unburned knot has been practiced thrift the energy, has reduced pollution; The permeable brick of ecological slag can also filter and purify simultaneously in infiltration water, helps the recycle-water resource; After the operating period of the permeable brick of ecological slag finishes, can also reclaim cycling and reutilization, the feature of environmental protection is good.Also have, the permeable brick of above-mentioned ecological slag is permeable, and is ventilative, guarantees that rain, snow, water etc. infiltrate the face of land rapidly, guarantee that the road surface is dry, and aspects such as ground moistening and the circulation of promotion soil atmosphere all has advantage; In addition; Can be according to the actual requirements; Add proper amount of silicon ash and pigment; The permeable brick of ecological slag that preparation is colored makes intensity, durability and the resistance to freezing and thawing of the permeable brick of ecological slag better, and can demonstrate fully the permeable brick of ecological slag at beautifying urban environment, enrich the city tone and improve unique charm in the appearance of city.
Further, because the permeable brick of above-mentioned ecological slag has certain porosity, intensity and freeze thawing all can be affected; So, in the preparation process, need to add a certain amount of Admixture; Underlying strength when improving the permeable brick moulding of ecological slag reduces the loss of freeze thawing to intensity; For further intensifying the activity of cement paste, adopt magnetized drinking water, to improve cement strength; The compressive strength and the durability National standard of the permeable brick of the ecological slag of gained can " be breathed " (being good water permeability), can increase the ventilative area of urban water-through; And resistance tocrocking is good, not influenced by adverse circumstances, the favourable ecological homeostasis, and market prospects are wide.

A1, in the ecological slag of 70-80 part, add the water of 0.595-0.80 part, be stirred to aggregate in the said ecological slag moistening after, the cement, the silicon ash of 2-5 part and the water of 2.38-3.2 part that add 16-20 part once stir;
A2, once stir when proceeding to 2-3min said, the melamine that in step a1 gained mixed material, adds 1-3 part carries out secondary stirring;
A3, when said secondary stirring proceeds to 0.5-1.5min; The water that in step a2 gained mixed material, adds 2.975-4.0 part; Carrying out three times stirs; Behind gained mixed material surperficial shinny, the gained material to be inserted in the underlying strength pervious layer feed bin, vibration is pressed into said underlying strength pervious layer.
8. the preparation method of the permeable brick of ecological slag according to claim 6 is characterized in that in step b, the preparation method of said sense organ pervious layer specifically comprises the steps:
B1, the curing compound of the water-base resin of 2-7 part and 3.4-11 part is inserted in the mixing device behind the mixing, slowly add the water of 3.4-6.6 part, once stir, when liquid that mixed material is creamy white, obtain adhesive;
B2, the quartz sand with 65-75 part, the cement of 17-22 part and the pigment of 3-4 part add in the mixer, carry out secondary stirring;
B3, behind said pigment and quartz sand and cement mixing, in said secondary stirring gained material, slowly add step b1 gained adhesive, carry out three times and stir;
B4, after said adhesive wraps up secondary stirring gained material fully, the gained material is put into sense organ pervious layer feed bin carries out secondary material distributing, the vibration extrusion modling.
