Abstract
The in-situ cast wall material consists of mainly cement, building garbage mixture or coal gangue, sand, flyash, etc. The wall of the material has low cost, light weight, high strength, less deformation and other advantages, and the present invention can reduce the amount of garbage and change waste into useful material.
Description
(1) technical field:
The invention belongs to a kind of material of construction, being specifically related to a kind of is the prepared cast-in-situ wall material of main raw material with building waste or coal gangue.
(2) background technology:
Present most of buildings of China, its materials for wall mainly are to add the water stirring after cement, sand, stone or the like mix by a certain percentage to make concrete and carry out the cast-in-place coagulation body of wall of making again.General wall thickness 240mm, cost is more than 70 yuan/square.Meanwhile, along with the continuous development of urban construction, remove or explosion after buildings institute depleted brick, watt, building wastes such as ash, sand, stone, concrete blocks, glass cullet can be found everywhere; How to solve the stacking of urban architecture rubbish and handle and become very stubborn problem of relevant department.For this reason, relevant ministries and commissions of country have put into effect relevant preferential policy, " encourage growth is energy-conservation, save land, sharp useless novel wall material ".Therefore, existing building waste if can be regenerated, turn waste into wealth, will be an economic benefit but also have the development projects of social benefit of benefiting the nation and the people, not only had.
In addition, China is a big coal country; The reserves of coal gangue are also very big.It is raw material brickmaking piece with the coal gangue that the people was once arranged, and its method is that coal gangue is built into body of wall after through fragmentation, oven dry, ball milling, steam-cured, baked wheaten cake moulding, carries out two-sided plastering again; The loaded down with trivial details complexity of its operation, the body of wall of making is thick partially, and construction is complicated.
(3) summary of the invention:
Purpose of the present invention is exactly that proposing a kind of is the cast-in-situ wall material of main raw material preparation with building waste or coal gangue; The body of wall comprehensive cost cast-in-place with this material can reduce about 20%, and body of wall is light, intensity height, and easy construction; Especially can consume a large amount of building wastes and coal gangue, turn waste into wealth, with low cost.
Main composition of the present invention and weight part are:
Cement 1 building waste mixture or coal gangue 1-4 sand 0-3
Coal ash 0.25-0.35 auxiliary material 0.3-0.4 additive 0.03-0.04
Above-mentioned building waste mixture be meant the brick that stays after demolishing buildings or the explosion, watt, ash, sand, stone, concrete blocks, glass cullet after break process particle diameter less than the sand grains meal of 5mm;
Above-mentioned coal gangue generally contains the coal amount less than 8%, and silt content is light brown red less than 3%; The powder shape of particle diameter less than 5mm is processed in fragmentation during use.
Cast-in-situ wall when construction, the broken building waste mixture that processes or coal gangue and sand, coal ash, auxiliary material, additive etc. are mixed by a certain percentage stir, amount of water is advisable between 110-130mm with the control degree of mobilization, on-the-spot pouring, once shaped.
Use the present invention cast-in-place body of wall be non-load bearing wall, mainly be suitable for the various civilian and commercial buildings partition of skeleton construction, can design any specification thickness according to user or designing unit's requirement.Its cost not only is lower than the red hollow brick in market slightly, the aerated-block body of wall, and also lower than Kodak board wall body, quality reaches the product operative norm Q/THQ001-2001 that Hubei Province Administration of Quality and Technology Supervision issues simultaneously, and the wall leveling degree reaches below the excellent engineering standard 3mm.It is simple and direct to construct, and synchronous disposal pouring typing of body of wall and door and window and installation reduce operation, need not two-sided plastering, and cost saving improves the building wall progress more than 3 times, and comprehensive cost reduces about 20%, and usable floor area increases 8-10%.Its preparation of construction can with " cast-in-place light concrete partition shaped device " (utility model patent 03255131.2) supporting use of inventor invention.Simultaneously, the present invention also can realize building waste, coal gangue, coal ash minimizing, turns waste into wealth, and benefits the nation and the people.
(4) embodiment:
Embodiment 1: get 32.5 cement 1000kg, building waste mixture 1000kg, sand 1000kg, coal ash 300kg, crown filler 150kg, lime 150kg, perlite 50kg, whipping agent 0.6kg, foaming agent 30kg, water reducer 0.6kg mixing and stirring adds water and controls degree of mobilization between 110-130mm, stirs into behind the slurry according to the cast-in-place once shaped of required wall thickness.
Embodiment 2: get cement 1000kg, and building waste mixture 2000kg, coal ash 350kg, auxiliary material 400kg such as the plaster of paris, lime, perlite, additive 40kg stirs, and constructional method is with embodiment 1.
Embodiment 3: get cement 1000kg, and coal gangue 2000kg, sand 2000kg, coal ash 400kg, auxiliary material 350kg, additive 35kg stirs, and constructional method is with embodiment 1.
