Embodiment 1

[0020] A new type of hollow / composite block that utilizes waste, is energy-saving and environment-friendly, and is manufactured and shaped on a block machine, such as figure 1 , 2 shown. The composition of the block matrix and the proportion by weight are: 30-60% of cement; 10-20% of construction waste; 20-30% of fly ash; 5-10% of industrial waste. The density grade of the block is closely related to the strength and thermal resistance of the block. Generally, the lower the density, the lower the compressive strength and the greater the thermal resistance. Therefore, the ratio of materials should be adjusted reasonably according to the actual requirements of block compressive strength and thermal performance. Fly ash can improve the working performance of the mixture and the performance of small blocks, and can replace part of the cement, saving cement Dosage.

Embodiment 2

[0022] A new type of hollow / composite block that utilizes waste, saves energy and protects the environment, such as image 3 As shown, the middle row of inner holes and the last row of outer holes are filled with thermal insulation materials in the manufactured block shell, so that the heat transfer coefficient of the block can be reduced and the energy saving of the block can be improved within an acceptable cost increment range. Effect. Such as Figure 4 As shown, the same thermal insulation material can also be filled in all inner and outer holes at the same time, so as to maximize the thermal insulation performance of the block.

Embodiment 3

[0024] A new type of hollow / composite block that utilizes waste, saves energy and protects the environment, such as Figure 5 As shown, the masonry method of the blocks is that each layer is composed of the blocks connected left and right, and the layers are built in the form of staggered seams and lap joints.

Abstract

The application discloses an energy-saving and environment-friendly hollow / composite building block. The building block consists of a building block housing, three rows of inner holes, two rows of outer holes and connecting ribs, wherein the hole ratio is 45-60 percent; the inner holes and the outer holes can be filled with heat insulating materials or not according to actual requirements. The energy-saving and environment-friendly hollow / composite building block has the advantages that the building block housing makes the best of local building rubbish, coal ash and other factory wastes, so that the materials are saved; the weight is light; the construction is convenient; excellent mechanical property is achieved; the heat transfer coefficients of all heat paths of the building block are equal, so that cold and hot bridges are reduced to the utmost extent; the requirements on energy-saving design standards of different regions and different building types can be met.

Description

technical field [0001] The application belongs to the field of building wall materials. Background technique [0002] In recent years, the rapid development of the construction industry has caused a huge amount of construction waste to be produced in my country every year, accounting for about 30% to 40% of the entire urban solid waste. Among these construction wastes, waste bricks account for the largest proportion, about 60%. At the same time, various natural disasters have also resulted in a large amount of construction waste. The Wenchuan earthquake on May 12, 2008 produced more than 500 million tons of construction waste. If calculated at 60%, the waste bricks produced will be 300 million tons. Recycling of construction waste can protect the environment and make limited resources reusable, which is of great significance for building energy saving and wall material innovation. [0003] In addition, fly ash has a large amount and a wide range, and it is also a "renewa...
