Description

A kind of alkaline residue building waste haydite and preparation method thereof
Technical field
The invention belongs to construction material preparing technical field, be specifically related to a kind of alkaline residue building waste haydite and preparation side thereof Method.
Background technology
Along with industrialization, the acceleration of urbanization process, building industry is the most fast-developing, with this together be building waste day by day Increasing, a large amount of building wastes not only occupy soil, and bring severe contamination to human habitat.According to statistics, I The every annual meeting of state increases building waste more than 4,000 ten thousand tons newly, and the quantity of building waste has accounted for more than the 1/3 of municipal refuse total amount, its Middle concrete construction rubbish has accounted for again more than the 40% of building waste.This phenomenon has been obtained for the extensive pass of the whole society Note.Land resource is not only wasted in storing up for a long time of building waste, easily produces potential safety hazard, is unfavorable for the sustainable development of resource Recycling with resource;And the heap of building waste is released and can be polluted water resource, has influence on air quality, and then Directly influence the living environment of the mankind.
Meanwhile, the high-rise frame structure building of China's fast development does not require nothing more than materials for wall high-strength light, simultaneously Frame structure to load-bearing it is also proposed the requirement of high-strength light.Haydite as the aggregate of a kind of high-strength light, have unit weight little, Intensity is high, particle diameter can divide the features such as multistage, hole is abundant, is just meeting the needs of modern architecture industry, and it replaces stone as coagulation Aggregate in soil, alleviates the 30% of fabric structure weight, improves the economic and technical norms of other side, and for carrying The shock resistance of high constructure is significant, and currently used haydite need to through 900-1100 DEG C of high-temperature calcination, energy consumption is high, Environment counter productive is notable, therefore, seeks alkaline residue building waste baking-free ceramicite the most for building further and becomes a reality institute Need.
Patent CN201110352340.7 discloses a kind of unburned spheroidal attapulgite building rubbish ceramic grain, unburned spheroidal The dispensing of attapulgite construction waste ceramsite is made up of following component by weight percentage: high viscous attapulgite clay powder 2~15%, Attapulgite clay mine tailing 5~25%, building waste powder 35~65%, red bentonite in powder 1~15%, kieselguhr mine tailing 1~15% and cement 5~25%;The production method of described unburned spheroidal attapulgite building rubbish ceramic grain: (1) is by unburned ball The dispensing of shape attapulgite construction waste ceramsite inputs granulating disc pelletize after adding stirrer for mixing, and particle diameter controls 3~30 millimeters;(2) granule after pelletize is transported to concrete curing indoor and carries out the conventional maintenance 28 days of cement products, pass through Unburned spheroidal attapulgite building rubbish ceramic grain it is packaged as after screening.Its major gelled material is the cement of >=42.5 grades, belongs to In traditional material, it is unfavorable for energy-conserving and environment-protective;The routine that burning spherical attapulgite construction waste ceramsite needs 28 days after the pelletizing is supported Protect, in production process store, turn around time oversize.
Summary of the invention
It is an object of the invention to provide a kind of alkaline residue building waste haydite and preparation method thereof.
A kind of alkaline residue building waste haydite, is made up of the material of following parts by weight: alkaline residue 100 parts, building waste 150- 600 parts, silicon ash 2-8 part, cement 10-25 part, alkali-activator 2.5-8.5 part, additive 0.06-1.5 part, water 13-35 part.
Described alkaline residue specific surface area >=350cm2/g。
Described alkali-activator is one or more in Calx, sodium silicate, dihydrate gypsum.
Described additive is organic silicon emulsion and hydroxypropyl methyl cellulose is combined formulated.
Described building waste is one or more in waste concrete, useless brick, waste marble and waste mortar.
Described cement is 42.5 Portland cements.
The preparation method of above-mentioned alkaline residue building waste haydite, is carried out in accordance with the following steps:
(1) building waste is less than 100 millimeters through large-scale broken hammer or crusher in crushing to particle diameter, then uses stone pulverizing Machine carries out being crushed to fineness of the particles less than 0.1mm;
(2) material is sequentially added into blender according to water, exciting agent, additive, silicon ash, alkaline residue, the order of building waste Middle stirring 3-5min;
(3) by the mixing material input granulating disc pelletize after stirring, particle diameter controls 1~30mm;
(4) granule after pelletize is transported to maintenance 1-7 days in temperature 20-50 DEG C, relative humidity 70-90% environment, makes Haydite.
Beneficial effects of the present invention: raw material of the present invention uses industrial residue and building waste, solid waste utilization rate is high, produce into This is low, it is possible to turns waste into wealth, not only achieves the recycling of the solid waste such as building waste, alkaline residue, improve enterprise Income, the problem of environmental pollution the most also brought by solid waste has searched out new outlet.Alkaline residue building waste haydite Moulding process is simple, it is not necessary to high-temperature calcination, and low-carbon (LC), environmental protection, energy consumption are low.Curing cycle is short, and maintenance just can use after 1-7 days, raw Product efficiency is high.Binder Materials is alkali-activated carbonatite alkaline residue Binder Materials, is different from traditional dense form water mudrock structure, mostly is inside it Class zeolite shape hydrated product, light weight porous and also intensity is high.Alkaline residue building waste haydite is rounded, rough surface and hard, There is trickle pore inside, have raw material sources extensively, light weight, apparent density be little, the high and low contraction of intensity, anti-carbonation, durability The advantages such as good, high temperature resistant, good heat insulating, water resistance are good.
