Embodiment 1

[0017] The regenerated building material described in this example, its components are proportioned by mass percentage: 18% cement, 60% regenerated orthopedics, 1% thickener, 3% compatibilizer, 1% processing aid, 1% ultraviolet absorber %;

[0018] Wherein, the cement is Portland cement, the regenerative orthopedics is solid particles with a particle size of less than 4.75mm pulverized from construction waste, and the thickener is cellulose ether.

[0019] Specifically, the preparation method of a regenerated building material comprises the following steps:

[0020] Step 1. Mixing and stirring: The regenerative orthopedics is treated with high temperature and harmless, and then cement, thickener, compatibilizer, processing aid and ultraviolet absorber are added, and then poured into the mixer and stirred until it is evenly stirred;

[0021] Step 2, pouring (extrusion) molding: add water to the mixed material treated in step 1 and stir until it is uniform to form a mixture, an...

Abstract

The invention discloses a recycled building material. The recycled building material comprises the following components by mass percent: 18%-38% of cement, 60%-80% of recycled aggregate, 1%-3% of a thickener, 3%-5% of a compatilizer, 1%-3% of a processing agent, and 1%-3% of an ultraviolet light absorber, wherein the cement is Portland cement, the recycled aggregate is solid particles with the grain size of less than 4.75 mm, the solid particles are prepared by pulverizing a building waste, and the thickener is cellulose ether. The recycled building material meets the performance requirement of the current recycled building material, the indexes like volume weight, compressive strength, fireproofing grade (A1 grade) and mechanical performance meet the related application standards, the recycling cost is relatively low, and practical use requirements are met.

Description

technical field [0001] The invention relates to a recycled building material and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] With large-scale urban construction and industrial development, the construction waste generated during the demolition and construction of construction projects is also increasing significantly year by year. The so-called construction waste is mainly composed of inorganic substances such as broken concrete, broken bricks and tiles, broken sand and gravel soil, and its chemical composition is silicate, oxide, hydroxide, sulfide and sulfate. It has very good strength, hardness, wear resistance, impact resistance flexibility, frost resistance, water resistance, etc., that is, high strength, good stability, etc. According to the information, the European Community countries discharge about 242 million tons of construction waste every year in the early stage of this century, the United...
