Abstract
The invention discloses an environmental-friendly cement tile mixed with ballast and a preparation method thereof. The environmental-friendly cement tile is prepared by adding ballast on the basis of a common cement tile raw material and comprises the following raw materials: 5-150 parts of ballast, 80-130 parts of cement, 0-165 parts of sand and 20-39 parts of water. Tests prove that the ballast added into the cement tile not only improves the breaking strength of the cement tile, but also can consume fine chips and stone chips generated in the process of mechanically processing broken stone in a plurality of waste quarries; and the invention utilizes the waste, saves resources and protects the environment. The invention plays an important role in the field of construction and has wide market prospect.
Description
Technical field
The present invention relates to building materials field, relate generally to utilization again, be specifically related to a kind of environment-friendly cement tile that is mixed with ballast and preparation method thereof industrial waste.
Background technology
In China, the mineral resources abundance, abundant mineral products have driven the development of stone material industry, and these enterprises have produced man-hour such as a large amount of barren rock quarrels, waste stone dust etc. adding.Developing rapidly of stone material industry makes barren rock quarrel, waste stone dust total amount increase year by year, and it is as the discarded deposit of building stones field, not only occupied ground but also contaminated environment.Thereby barren rock is cut, the processing of waste stone dust has become serious social concern.
The historical far away stream of cement tile (having another name called concrete tile) is long, the sector be China the most traditional, also be one of small investment, widespread production industry.Common cement tile is a basic material with cement, sand and water, and the main cementitious material of using when cement tile is produced is a cement, and Cement Production belongs to high energy consumption, high pollution, and is very big to resource and environment damage.Existing document introduction can be mixed flyash or heavy blast furnace slag (Zhou Zhihong in the cement tile batching, Chen Xun, Cui Tiansheng, Zhang Yun's ripple. utilize heavy blast furnace slag and flyash to produce colour concrete watt. brick and tile, 2003 (6): 42-45.), utilize wherein active silica and alundum (Al under the high situation of calcium hydroxide content, to form hydrated calcium silicate gel (C-S-H gel) and drated calcium aluminate gel with calcium hydroxide generation secondary response, the result is in cement tile behind adding coal ash or the heavy blast furnace slag, on the basis that utilizes industrial residues such as flyash or heavy blast furnace slag, the every performance of cement tile all reaches the requirement of JC 746-2007 " concrete tile " standard high-class product.But, there is not bibliographical information so far for the application of ballast in cement tile.The ballast aboundresources, cheap, mix in the cement tile and can reduce production costs; The ballast resource is utilized again on the other hand, can solve not only that stone material already develops and the environmental protection difficult problem brought, and the Recycling of ballast allows the barren rock quarrel turn waste into wealth, and realizes the doulbe-sides' victory of benefit and environmental protection.Thereby with ballast preparation cement tile technology be a kind of press for to have energy-conservation profit useless and reduce the novel ballast cement tile preparation technique of advantages such as product cost.
Summary of the invention
The invention provides a kind of can be the environment-friendly cement tile of raw material preparation with ballast, is utilizing waste resource, when reducing part cement, river sand consumption, can also work in coordination with other cement tile batching and play a role, and improves the cement tile performance.
For reducing the cement tile production cost, solve the problem of environmental pollution that ballast brought, the present invention takes following technical scheme: a kind of environment-friendly cement tile that is mixed with ballast is to add the environment-friendly cement tile that ballast prepares on the basis of ordinary Portland cement watt raw material.
Specifically, the described composition of raw materials that is mixed with the environment-friendly cement tile of ballast comprises following components by weight portion: ballast 5-150 part, cement 80-130 part, sand 0-165 part, water 20-39 part.
Described ballast be the quarry in the process of machining rubble, producing about 20% particle diameter is 0.16～5.00mm fines and/or aggregate chips, fineness modulus is 3.2-3.6.
Described cement is preferably silicate series cement or sulphate aluminium cement.
It is that 2.3-3.0, mud content are the natural sand of 0-2.0% that described sand is preferably fineness modulus.
Second purpose of the present invention provides a kind of preparation method of environment-friendly cement tile.
The preparation method of environment-friendly cement tile provided by the present invention can may further comprise the steps:
1) getting material by following parts by weight proportioning mixes: ballast 5-150 part, and cement 80-130 part, sand 0-165 part, water 20-39 part mixes above-mentioned raw materials;
2) compression moulding; Pressure 6-20MPa, the pressurization retention time is more than 2 seconds;
3) maintenance: after the demoulding, maintenance immersion after 24 hours under the situation of trickle not, trickle or natural curing.Obtain environment-friendly cement tile.
The invention provides a kind of environment-friendly cement tile that is mixed with ballast.This material is the part cement that adopts in the alternative traditional cement tile of discarded ballast, and itself and cement, sand, water etc. are evenly mixed the environment-friendly cement tile that obtains by a certain percentage.Experiment showed, that the ballast that adds in this material not only can improve the rupture strength of cement tile, can also consume a large amount of ballasts, reduce part cement, river sand consumption, utilized discarded object, saved resource and protected environment.
The specific embodiment
The present invention is mixed with the environment-friendly cement tile of ballast, is the environment-friendly cement tile that is added with ballast on the basis of ordinary Portland cement watt production.Suitable the present invention is mixed with the composition of raw materials of the environment-friendly cement tile of ballast, comprises following components by weight portion: ballast 5-150 part, cement 80-130 part, sand 0-165 part, water 20-39 part.
Here, ballast is preferably the quarry in the process of machining rubble, and the particle diameter of generation about 20% is 0.16～5.00mm fines and/or aggregate chips, and fineness modulus is 3.2-3.6.The inventor sums up in research practice: on mechanism, 1) the ballast quality is hard, rough surface, has sharp corners, make gather materials with and cement between, the snap-in force between the aggregate is enhanced, adhesive property is strengthened, the boundary strength of aggregate-cement paste in the raising cement briquette; The stone flour particulate that contains in the ballast can make the bleeding of cement mixture reduce simultaneously, is beneficial to the interface bonding development of cement briquette.2) because the stone flour particulate that contains in the ballast has been filled the space in the cement stone, make the macropore of cement stone fined, improved its internal voids structure, make cement stone fine and close more; The effect that disperses cement granules is played in the introducing of stone flour simultaneously, makes hydrated cementitious more abundant, is beneficial to the development of intensity.3) contain SiO by measuring as can be seen in the ballast
2, CaO isoreactivity composition accounts for 57.55%, in the process of hydrated cementitious, easily form hard calcium aluminosilicate and calcium bicarbonate, thereby improve concrete intensity.Therefore, use ballast not only to be embodied in the twice laid aspect, also have the advantage that promotes cement tile quality aspect.
Cement is preferably silicate series cement or sulphate aluminium cement.
It is that 2.3-3.0, mud content are the natural sand of 0-2.0% that sand is preferably fineness modulus.The use of sand is decided as circumstances require, even can replace sand to use fully with rock ballast.
