Embodiment

[0047] Such as Figure 1 to Figure 6 As shown, in this embodiment, a renewable composite admixture using construction waste and a preparation method thereof are made from the following raw materials in parts by weight: 30 parts of concrete, 40 parts of sintered bricks, 10 parts of decoration slag, 5 parts of pulverized coal Ash, 10 parts of electric furnace steel slag, 5 parts of basalt and 0.125 parts of grinding aid. The preparation process is described in detail below:

[0048] (1) Raw material pretreatment:

[0049] (1) Pretreatment of construction waste: crushing, removing iron and screening construction waste to obtain construction waste particles with a diameter of 20-50 mm; among them, construction waste is divided into concrete, sintered bricks and tiles, and decoration slag. In this embodiment, the construction waste is crushed and impurity-removed. The crushed building slag particles with a particle size of 20-50 mm are transported to the silo for storage by the homoge...

Abstract

The invention discloses a regenerated composite admixture utilizing construction waste. The regenerated composite admixture is prepared from the following raw materials in parts by weight: 30 parts ofconcrete, 40 parts of sintered bricks, 10 parts of decoration slag, 5 parts of fly ash, 10 parts of electric furnace steel slag, 5 parts of basalt and 0.125 part of a grinding aid. The invention further provides a preparation method of the regenerated composite admixture utilizing construction waste.

Description

Technical field [0001] The invention relates to the technical field of construction waste recycling, in particular to a recycled composite admixture using construction waste and a preparation method thereof. Background technique [0002] With the continuous development of urban construction and the increase in waste, the recycling of construction waste is of urgency. The construction waste mentioned in this article refers to the waste concrete / mortar / bricks / tiles / glass generated by construction units, construction units newly built, rebuilt, expanded and demolished various buildings, structures, pipe networks, etc., and residents decorating houses / Ceramics, spoils, materials and other wastes. According to incomplete statistics, the amount of construction waste generated in the process of urban construction in my country has accounted for 30%-40% of the total urban waste, making it the largest source of urban waste. However, at present, only tens of millions of tons of constru...
