Abstract
The invention relates to a high-performance mortar formula based on a recycled material and a preparation method thereof, and the high-performance mortar based on the recycled material is formed by mixing 30-45% of construction waste recycled aggregate, 10-20% of stones, 20-50% of cement and 2-5% of an additive.
Description
Technical Field
The invention relates to the field of mortar formulas, in particular to a mortar formula prepared based on a recycled material.
Background
With the acceleration of the national urbanization process and the acceleration of urban construction and transformation, the yield of the construction waste is increased year by year, the current storage amount of the construction waste is about 25-30 hundred million tons, but the resource utilization rate is low and is far from the utilization rate of more than 90 percent in Europe, America, Japan, Korea and the like, and the low-end resource utilization forms such as road filling and the like are mainly used, so that the feasible high-end utilization technology is lacked.
Disclosure of Invention
In order to solve the problems of low utilization rate and single utilization form of the existing construction waste, the invention provides a high-performance mortar formula based on a recycled material and a preparation method thereof.
The technical scheme adopted by the invention for solving the technical problems is as follows: a high-performance mortar formula based on a recycled material is prepared from the following raw materials: 30-45% of construction waste recycled aggregate, 10-20% of stones, 20-50% of cement and 2-5% of additive.
As an improvement of the high-performance mortar formula based on the recycled material, the diameter of the construction waste recycled aggregate is 0.01-0.05 mm.
As an improvement of the high-performance mortar formula based on the recycled material, the additive is prepared by fully mixing 20-40% of a defoaming agent, 40-50% of a water reducing agent and 30-50% of a retarder.
As an improvement of the high-performance mortar formula based on the recycled material, the cement is 42.5 of ordinary cement.
A preparation method of a high-performance mortar formula based on a recycled material comprises the following steps:
screening the recycled aggregate of the construction waste to be 0.01-0.05 mm in diameter by a screening machine;
screening the stones with the diameter not more than 10mm by using a screening machine;
thirdly, mixing the screened construction waste recycled aggregate, the gravel, the cement and the additive in proportion;
and fourthly, mixing, adding water for use or storing in a dry mode.
According to the high-performance mortar formula based on the recycled material and the preparation method thereof, the construction waste can be highly utilized again through a reasonable formula and a reasonable method, so that the damage of the construction waste to the environment is reduced, the cost for mining or purchasing natural ores by enterprises is reduced, and better benefits are brought to the enterprises.
