Abstract
The invention discloses a steel fiber/fly ash/red mud water-permeable brick and a preparation method thereof. The steel fiber/fly ash/red mud water-permeable brick is prepared from the following raw materials in parts by weight: 50-70 parts of steel fiber, 15-20 parts of red mud, 20-30 parts of fly ash and 30-40 brick slag particle. The invention also discloses a preparation method of the water-permeable brick. The steel fiber, brick slag particle, fly ash and red mud used as the raw materials are mixed to prepare the water-permeable brick. The brick slag and fly ash are recovered wastes, the red mud is the recovered low-cost raw material, and the cost of the steel fiber is not high; and thus, the low-cost raw materials are utilized to recycle the wastes. The raw materials are sintered at sintering temperature to obtain the high-strength high-water-permeability high-wear-resistance water-permeable brick.

Background technology
The common floor tile that urban surface is laid, arranging the earth's surface after rainwater can because Long Term Contact causes surface sealing less than moisture, and more serious long meeting causes continual land subsidence.Therefore need to adopt water-permeable brick could solve this thorny problem.
Conventional common water-permeable brick: material is the repressed shaping of cellular concrete material of common rubble, for general block pavement, square, is the product that generalization is mated formation.Its intensity is low, wears no resistance, and causes its work-ing life low.
Also has a kind of polymer fiber concrete permeable brick: material is granite aggregate, high-strength cement and cement polymer toughener, and fusion polypropylene fibre, feeding proportioning are tight, through press forming after stirring, be mainly used in the mating formation of the place such as pavement, square, parking lot of municipal administration, important engineering and residential quarters.The third water-permeable brick is concrete permeable brick: material is river sand, cement, water, then the concrete product adding a certain proportion of impregnating agent and make.This product is compared with resin water-permeable brick, ceramic water-permeable brick, gap water-permeable brick, and production cost is low, and Making programme is simple, easy to operate.Be widely used in expressway, airport runways, driveway, the scopes such as walkway, square and garden architecture.Although its intensity is taken on a new look to some extent than common water-permeable brick, strength enhancing is limited, and its cost of manufacture is high.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of steel fiber coal ash red mud water-permeable brick and preparation method thereof, this product has and keeps water-permeable, the moisture retention on ground, the feature such as anti-skidding, high strength, high abrasion, weather resistance, noise reduction, sound-absorbing.It adopts brick slag, flyash and red mud waste material to be raw material, shaping through brick press, sintering.Technique is simple to operation.
The object of the invention is to realize in the following manner:
A kind of steel fiber coal ash red mud water-permeable brick, is prepared from by the raw material of following weight part: steel fiber: 50-70, red mud 15-20. flyash 20-30, brick solid impurity particle 30-40.
Described length of steel fiber is 30-40mm, and diameter is 0.3-0.4mm, and length-to-diameter ratio is 35.
Described brick slag particle degree 5-8mm.
Above-mentioned steel fiber coal ash red mud water-permeable brick, optimum formula is as follows: be prepared from by the raw material of following weight part: steel fiber: 60, red mud 18 flyash 25, brick solid impurity particle 35.
The preparation method of above-mentioned steel fiber coal ash red mud water-permeable brick: obtained by following steps:
(1) raw material mixing: add water steel fiber, red mud, flyash and brick solid impurity particle mixing, and moisture control is at 15-25%;
(2) shaping: by the raw material input brick press mixed, shaping adobe;
(3) maintenance: natural curing, envrionment temperature 5-35 DEG C, curing time is 3-5 days;
(4) fire: fire, kiln is put in adobe, with the temperature rise rate of 350-400 DEG C/h, furnace temperature is grown to 1000-1200 DEG C, insulation 1-2 hour, then naturally cools to room temperature, obtains water-permeable brick.
fig. 1sintering temperature curve:
Relative to prior art, the present invention has following advantage: the present invention with steel fiber, brick solid impurity particle, flyash and red mud for raw material, water-permeable brick is prepared after mixing, brick slag in its raw material and flyash reclaim waste material, and red mud is also the low cost raw material after recycling, and steel fiber cost is not high yet, use these low cost raw materials, not only waste material re-uses, and by sintering temperature of the present invention, sinters the water-permeable brick with high strength, high water-permeability and high-wearing feature into.
Inhale the feature that water-permeable brick has following 5 aspects for this:
First, there are good permeable, permeability, rainwater can be made to permeate the ground rapidly, supplement the soil water and underground water, keep soil humidity, improve the life condition of urban ground plants and soil microorganism.Municipal drainage and pressure of flood can be alleviated simultaneously, there is good effect to preventing the pollution of public waters and disposing of sewage, to make on road not ponding.Secondly, Absorbable rod moisture and heat, regulate the humiture of earth's surface local space, has larger effect to adjustment urban microclimate, alleviating urban heat island effect.
Finally, the water-permeable on ground, moisture retention can be kept, anti-skidding, high strength, wear-resisting, weather resistance, long service life.
