Embodiment Construction

[0045] like figure 1 Shown, it is the machine-made black brick of common brick type of the present invention, and its preparation material contains the raw material of following parts by weight: 1028 parts are made of sintered products (such as clay bricks, earthen pots and broken glass fragments, etc.) Garbage broken material, 280 parts of cement, 910 parts of lime sludge soil, 67 parts of blue ash and 115 parts of water; wherein the particle size of the construction waste broken material is below 10 mm.

[0046] In order to make the color of the machine-made green brick closer to that of the fired clay brick, 0.5 part of pigment is added to the preparation to adjust the color.

[0047] The manufacture method of the machine-made green brick of common brick type of the present embodiment comprises:

[0048] - Classify the construction waste first, and first pick up and screen the construction waste materials of sintered products (such as clay bricks, crock pots and broken glass...

Abstract

The invention discloses a gray brick mechanically manufactured from lime sludge and construction wastes and a method for manufacturing the same. The materials for mechanically manufacturing the gray brick comprise the following raw materials in portion by weight: 1,015 to 1,135 portions of construction waste crushed materials, 240 to 290 portions of cement, 810 to 1,010 portions of lime sludge, 60 to 75 portions of gray lime, and 100 to 125 portions of water, wherein the particle size of the construction waste crushed materials is less than 15 millimeters. If necessary, less than 20 portions of fly ash and proper amount of activating agent can be added to the materials. The method for mechanically manufacturing gray brick comprises the following steps: firstly, crushing the construction wastes; secondly, mixing the construction waste crushed materials with the other materials according to the proportions; and thirdly, pressing the mixture by adopting a mechanical method so as to produce the gray brick of the invention. The gray brick and the method for manufacturing the same recycle the sludge and the construction wastes in a reducing, harmless and resource-utilizing mode, and solve the problem that substituting materials and products are hard to find after clay bricks are forbidden to use and the problem of gray brick sources for civilian constructions.

Description

technical field [0001] The invention relates to a building masonry material. Specifically, the present invention relates to a building block with properties such as water repellency and non-sintering produced by using lime sludge soil and construction waste as raw materials and adopting a mechanical pressing method. Background technique [0002] Green bricks play an important role in the history of Chinese architecture. Many imperial palaces and mansions are built with green bricks. In recent years, blue brick buildings have gradually developed towards the direction of public demand. However, due to the requirements of environmental protection, the production of traditional clay-fired blue bricks has been gradually restricted, and my country will completely ban the production of clay bricks in 2010. Like this just needs to produce a kind of substitute product to meet the needs of residential building demand and ancient building maintenance. [0003] Some technical schemes...
