Embodiment 1

[0009] Example 1: The weight ratio of cement: construction waste: water is 1:6:2.2.

Embodiment 2

[0010] Example 2: The weight ratio of cement: construction waste: water is 1:8:1.8.

Embodiment 3

[0011] Example 3: The weight ratio of cement: construction waste: water is 1:10:2.2

[0012] Stir uniformly according to the above ratio and use molding machinery to produce cement products of various shapes. In its production; if the temperature during the solidification period is above 28 degrees Celsius, cover the straw mats, water 1-2 times a day, and the temperature is 0 degrees Celsius The following needs to be insulated production.

[0013] This product has passed inspection and proved that the product produced meets the relevant national quality standards for cement products.

Abstract

The invention relates to a method for producing cement products by recycling construction waste. Firstly, the construction waste is classified, metal, wood and plastic waste are removed, and then crushed into granules, and Portland cement and water are added according to the proportion of concrete. , Stir evenly, and use the molding machine to produce cement products of various shapes. The present invention makes full use of the concept of turning construction waste into treasure to protect the environment, because the method of the present invention can produce a variety of cement products from construction waste, such as block bricks, etc., which can replace some existing cement products and ordinary cement products. Uses of clay fired bricks. The invention also reduces the traditional method of obtaining stone materials from mountain development to make cement products, reduces water and soil loss, has relatively low cost, is energy-saving and environment-friendly, and realizes recycling of waste.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a method for producing cement products such as building bricks and cement cuts by using construction waste, and belongs to the technical field of the International Patent Classification CO4B. Background technique [0002] With the rapid development of urban construction in our country, urban renewal and old city reconstruction, the demolition of old buildings and shanty towns have caused a large amount of construction waste. According to statistics, the discharge of construction waste has accounted for more than 30% of the total amount of urban waste. With the introduction of the problem that construction waste is difficult to dispose of, construction waste not only occupies limited land in the city, causes a large amount of accumulation, which affects the beauty of the city, but also affects the environmental protection of the city, which has gradually become one of the urban public...
