Technical field
The invention belongs to the Light trabs technical field, relate in particular to a kind of Light trabs and method of manufacture thereof of utilizing flyash to make.
Background technology
In order to satisfy the different demands of construction market, materials for walls such as heat-insulation wall plate, sound insulation wallboard, exterior wall wallboard, decorative wall panels have appearred on the market.Country and place and relevant department have all clearly stipulated to classify wallboard as the new wall material kind of emphasis support development.The residing position of wallboard is different, and its starting material constitute, manufacturing technique requirent also is not quite similar, and many kinds, seriation are the needs of development of the situation.
The production aspect of the existing light wall material of present China; Chinese invention patent ZL200610070220.7 has introduced a kind of light wallboard of desulfurated gypsum; It is to be processed by the raw material of following weight part: 100 parts in desulfurated plaster powder, polystyrene foam particles 3-10 part, flyash 30-80 part; Ordinary Portland cement 1-5 part, 8% compositions such as polyvinyl alcohol water solution 1-3 part.
A kind of Light trabs and ME thereof have been introduced in Chinese invention patent application 200810159083.3, comprise that following raw materials by weight percent processes: slag 30%, below the granularity 8MM; Flyash 35% is below the granule diameter 2MM; Building waste 15% is below the granularity 8MM, powder containing quantity is below 10%; Cement: 20%; In addition, add water reducer, hydrophober, accelerating chemicals again; The water that adds said slag, flyash, building waste, cement siccative composition weight summation 17~22% again.
But above Light trabs shrinking percentage is high, ultimate compression strength is poor, and particularly ultimate compression strength does not reach requirement again far away, can not be applied to the demanding occasion of resistance to compression.
Summary of the invention
The objective of the invention is to the deficiency to prior art, and a kind of Light trabs that utilizes flyash to make is provided, this Light trabs shrinking percentage is little, ultimate compression strength is high.
Another object of the present invention is to provide a kind of method of manufacture of utilizing the Light trabs of flyash manufacturing, need not flyash is dewatered and drying treatment, directly use to get final product, production efficiency is high, and cost is low.
The present invention realizes through following technology.
A kind of Light trabs that utilizes flyash to make, it comprises the raw material of following weight part:
Flyash 90-120 part
Building waste 30-50 part
Feldspar in powder 40-60 part
Pearlstone 10-40 part
Cement 40-60 part.
Preferably, it comprises the raw material of following weight part:
Flyash 80-100 part

Cement 40-50 part.
More preferred, it comprises the raw material of following weight part:
90 parts in flyash
35 parts of building wastes
55 parts of feldspars in powder
15 parts of pearlstones
45 parts of cement.
Wherein, said building waste be brick, watt, in stone, soil and the concrete blocks one or more mix by arbitrary proportion.
Wherein, the particle diameter of said feldspar in powder is below 100 orders.
Wherein, said flyash is the desulfurized powder coal ash.
Wherein, said cement is ordinary Portland cement.
A kind of method of manufacture of utilizing the Light trabs of flyash manufacturing, it may further comprise the steps:
A, the building waste of above-mentioned formula ratio is crushed to below 200 orders, mixes the back granulation,, obtain roasting particle after the cooling at 1150-1500 ℃ of roasting 20-120 minute with the feldspar in powder of the flyash that accounts for above-mentioned formula ratio 2/3, above-mentioned formula ratio;
B, the roasting particle that step a is obtained and the pearlstone of the cement of above-mentioned formula ratio, the flyash that accounts for above-mentioned formula ratio 1/3 and above-mentioned formula ratio stir in stirrer, obtain mixture;
The water that c, adding account for step b mixture 5%-20% weight percent continues to be stirred to evenly, obtains mixture for use;
D, the mixture for use that step c is obtained add moulding in the model, the demoulding and maintenance, obtain a kind of Light trabs that utilizes flyash to make.
Wherein, also can add a kind of in pigment, river sand or the concrete admixture or any several kinds among the said step b, can add in right amount according to demand.
Beneficial effect of the present invention is:
(1) flyash in the raw material contains a large amount of organic compositions; In roasting particle, produce disconnected space; And finally reduce the unit weight of Light trabs; Flyash in the raw material and pearlstone also play the purpose that reduces Light trabs unit weight, and building waste in the raw material and feldspar in powder improve roasting particle intensity, thereby have increased the ultimate compression strength of Light trabs.The Light trabs shrinking percentage that the present invention makes is little, light weight, ultimate compression strength high; Its weight is 1/16 of common brick " 49 " wall weight; Be about 1/2 of new GRC wallboard weight, ultimate compression strength has more good physical and mechanical property up to 60-120MPa than general natural rock;
(2) the present invention uses a large amount of building wastes, flyash; The product cost that makes is low; Economic benefit is high, not only can turn waste into wealth, and help improving environmental pollution; Meet innoxious, the minimizing and the resource utilization principle of China's solid waste disposal, have remarkable economic efficiency and social benefit.
