Abstract
The invention provides a floor tile with a super strong water penetrating performance and a preparation method thereof. The floor tile is prepared from the following components in parts by weight: 42 to 56 parts of cement, 18 to 27 parts of residential heating furnace slag, 32 to 38 parts of fly ash, 20 to 26 parts of ceramic particle, 5 to 12 parts of desulfurized gypsum, 4 to 8 parts of nylon fiber, 1 to 3 parts of higher fatty acid salts, 0.8 to 1.5 parts of adhesive, and 30 to 43 parts of water. Solid wastes such as residential heating furnace slag, fly ash, desulfurized gypsum, and the like, are taken as the main raw materials, the production cost of floor tile is largely reduced; at the same time, clay is not used, thus the step of calcination is not needed, the energy is saved, the environment is protected; under the situation that the porosity and water permeability are guaranteed, the compression strength of the provided floor tile can reach 40 MPa or more, and the rupture strength can reach 4.5 MPa or more.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of high-strength water-permeable floor tile and preparation method thereof.
Background technology
Floor tile to bear bigger pressure, it is therefore desirable to higher intensity.Existing floor tile degree of compaction is higher, such as concrete floor brick, concrete, Macroscopic single crystal floor tile, floor tile etc., these floor tiles are by same material one-shot forming, internal material hole is less, and, do not connect between hole, waterproof, cut off roadbed to exchange with extraneous, destroy natural ecological environment.The floor tile of existing water penetration, uses ceramic material sintering to make, though there being certain pervious function, meeting ecological demand, but power consumption is high, fire middle waste mass energy, and consume the clay resource of preciousness.If increasing merely the porosity of existing concrete floor tile, again can not the comprcssive strength requirement of face brick contentedly, when for driveway, easily crush.
Dank floor tile is a kind of novel high osmosis ground surface material, is made up through special process of the gathering materials of certain grating, cement, extraordinary cementing agent and water etc..Compared with Common Concrete Pavement brick, maximum feature is that coefficient of permeability is big.When raining, rainwater can be permeated the ground by pavior brick in time, or is stored in the space of floor tile, reduces surface gathered water.Dank floor tile can be widely used for the laying on the road surfaces such as house, garden, park, square, botanical garden, gardens, factory area, parking lot, tree well, greenhouse, pavement and light duty traffic highway, has good society, environment and ecological effect.
The physical and mechanical property of Dank floor tile typically requires to reach following index: (1) comprcssive strength >=30.0MPa；(2) rupture strength >=3.5MPa；(3) coefficient of permeability >=2.0mm/s(4) mill hole length≤35mm.And produce water-permeable concrete floor brick with solid waste aggregate at present and nearly all do not reach above-mentioned technology requirement.Being primarily due to solid waste aggregate crush index value apparently higher than natural aggregate, intensity is relatively low, and then causes the service life of product relatively low.
Owing to Dank floor tile has good permeable, permeability, rainwater can be made quickly to permeate the ground, supplement the soil water and subsoil water, keep soil moisture, improve the conditions of existence of urban ground plant and soil microorganism, be used for the most more and more widely laying square and crossing.Traditional water-permeable brick is many to be made so that common rubble is prepared as celluar concrete, or the concrete permeable brick made for raw material with river sand, cement, water and impregnating agent, or is the polymer fiber concrete permeable brick of higher level, ecological sand base water-permeable brick etc..
Summary of the invention
It is an object of the invention to make full use of existing resource, select solid industrial waste material as raw materials for production, it is provided that a kind of technique is simple, with low cost, and intensity is high, high-strength water-permeable floor tile with good water permeability and preparation method thereof.
