Abstract
The invention relates to a recycled aggregate-containing porous non-fired product preparation method, a finished porous non-fired product is prepared from raw materials of cement, 40-65 parts of fly ash, recycled aggregate, straw and / or rice husk, a foaming agent and the like by mixing, stirring, moulding, steam curing and other process steps, and has good heat insulation performance, due to addition of modified plant fiber, the product crack resistance can also be improved, and the solid waste can be fully used to achieve reuse of waste resources.
Description
Technical field
The present invention relates to a kind of preparation method of the unburned goods of porous containing regeneration aggregate, be specifically related to utilize rejected fly ash and regeneration aggregate to prepare the method for baking-free building block.
Background technology
China has a large amount of rejected fly ashes every year, is mainly derived from power plant, mining area, and flyash is only marginally for fertilizer in recent years, and more flyash goes out of use and causes great destruction to environment.But flyash is attempted it can be used as building materials raw material owing to having certain active people, but poor performance.Same building castoff deposits superincumbent problem too.And flyash and building castoff are prepared into the burden that baking-free building block not only can alleviate environment, also turn waste into wealth simultaneously, save natural resources, the product performance excellent in toughness be simultaneously made up of it is good, be incubated, heat insulation.
Summary of the invention
The object of this invention is to provide a kind of baking-free building block making method containing regeneration aggregate, technique is simple, and high to utilization rate of solid waste, described baking-free building block is lightweight, intensity better, good endurance, to the less environmentally safe of energy consumption.
Technical solution of the present invention is: raw material (by weight) adopts cement 10-15 part, flyash 40-65 part, regeneration aggregate 8-11 part, sulfonated lignin 0.1-0.5 part, sodium hydroxide 3-6 part, stalk and/or rice husk 10-15 part, ether of cellulose 3-5 part and water 5-10 part, whipping agent 0.1-0.5 part, water reducer 0.05-0.2 part, through mixing and stirring, again in mould through vibration, adobe is made in extrusion molding, vapor cure is after 48 hours, by its at normal temperatures outdoor placement 5-10 days obtain finished product, described stalk and/or rice husk are through modification, following steps are utilized to carry out modification to it, first stalk and/or powdered rice hulls are broken into the particle that diameter is 3-6mm, then be placed on by (by weight percentage) 5-10% nano silicon, 5-10% nano-calcium carbonate, 20-30% benzene emulsion, dip treating in the solution that 10-15% citric acid and 35-50% water are mixed with, wherein (by weight) described stalk and/or rice husk: above-mentioned solution is 1:5-10, described regeneration aggregate is obtained by following manner, and it adopts discarded concrete, discarded brick or waste ceramic as regeneration aggregate raw material, by above-mentioned regeneration aggregate raw material crushing for being less than 25mm,
Described flyash can be one-level or second class powered coal ash;
Slag and 1-2 part hardening accelerator of 10-20 part also can be added in above-mentioned raw materials.
Advantageous Effects of the present invention:
Present invention process step less cost is lower, can make full use of solid waste, described baking-free building block is lightweight, intensity better, toughness and good endurance, to the less environmentally safe of energy consumption.
