Abstract
The invention relates to a method for preparing a building material by utilizing recycled aggregates and modified plant fibers. The method is simple in process and high in utilization rate of solid wastes; a baking-free brick is light in weight, relatively good in strength, good in durability, good in toughness and crack resistance, low in energy consumption and free of environmental pollution; raw materials include cement, the recycled aggregates, the modified plant fibers and the like and are mixed and uniformly stirred, vibrated and extrusion-molded in a mold to form a brick blank; the brick blank is maintained with steam and then arranged outdoors at normal temperature for a certain time to obtain a finished product.
Description
Technical field
The present invention relates to a kind of non-burning brick method, be specifically related to utilize a kind of method utilizing regeneration aggregate and modified plant fibers to prepare material of construction.
Background technology
China has a large amount of discarded regeneration aggregates every year, is mainly derived from Industrial buildings and daily life etc., and regeneration aggregate bulk deposition is discarded causes great destruction to environment.But regeneration aggregate is attempted it can be used as building materials raw material owing to having certain intensity people, just poor performance.And regeneration aggregate is prepared into the non-burning brick burden that not only can alleviate environment, and also turn waste into wealth simultaneously, save natural resources, the non-burning brick excellent property insulation of being simultaneously made up of it, heat insulation.
Summary of the invention
The object of this invention is to provide a kind of Burning-free brick production method, technique is simple, high to utilization rate of solid waste, described non-burning brick lightweight, intensity better, good endurance, to the less environmentally safe of energy consumption, utilize again the natural plant fibre of modification that its toughness and splitting resistance are significantly strengthened simultaneously.
Technical solution of the present invention is: raw material (by weight) adopts cement 9-18 part, regeneration aggregate 35-68 part, silicon ash 9-15 part, redispersable latex powder 10-20 part, gypsum 3-8 part, vegetable fibre 10-15 part, Walocel MT 20.000PV 3-5 part, water 5-10 part, above-mentioned raw materials is through mixing and stirring, adobe is made through vibration, extrusion molding again in mould, after vapor cure 24-48 hour, by its at normal temperatures outdoor placement 12-15 days obtain finished product; Described vegetable fibre is stalk, wood fibre or straw, above-mentioned vegetable fibre is through modification, following steps are utilized to carry out modification to it, first vegetable fibre being ground into diameter is 3-6mm, then dip treating in the solution be mixed with by (by weight percentage) 5-10% nano silicon, 5-10% nano-calcium carbonate, 20-30% benzene emulsion, 10-15% citric acid and 35-50% water is placed on, wherein (by weight) vegetable fibre: 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.
Advantageous Effects of the present invention:
Present invention process is simple, high to utilization rate of solid waste, described non-burning brick lightweight, intensity better, good endurance, to the less environmentally safe of energy consumption, lightweight and pollution-free, product splitting resistance, toughness are better.
