Abstract
The invention discloses a wall supporting brick, a preparation method and an application thereof. The wall supporting brick is mainly made of the following components by weight proportion: 30-60 portions of building waste grains, 10-40 portions of cement and 0.5-2 portions of additive. The wall supporting brick is mainly made from the building waste, and has the advantages of saving cost and minimizing the pollution or influence to the surrounding environment caused by demolition of the buildings. The properties of the wall supporting brick accord with the standards or requirements for building materials, and the wall supporting brick can be completely used as a wall support material as the existing supporting bricks. Detections prove that the wall supporting brick has the compressive strength of 7.5-10MPs and the water absorption lower than the existing solid clay bricks and normal cement blocks.
Description
Technical field
The present invention relates to a kind of constructional materials, relate in particular to a kind of bearing brick of building wall, its preparation method and application, belong to building material field.
Background technology
Stay a large amount of cement, brick the like waste matter behind the demolishing buildings, these waste materials are because most value of not utilizing once more all is used as garbage disposal.Handle these waste materials and need expend a large amount of man power and materials on the one hand, also environment has on every side also been caused pollution in various degree on the other hand.
If can these construction waste materials are recycling in addition, not only saved cost of production, and destroyed after having alleviated of the pollution of these waste materials greatly environment.
Summary of the invention
The present invention's technical problem at first to be solved is to overcome the deficiencies in the prior art, a kind of bearing brick of building wall is provided, the key component of this bearing bricks is the obsolete material or the rubbish of building, every performance of this bearing bricks meets the standard or the requirement of constructional materials fully, can equally with existing bearing bricks use as the building bearing material.
The present invention's technical problem at first to be solved is achieved through the following technical solutions:
A kind of bearing brick of building wall, mainly form by the component of following weight portion:
Building discarded object particle 30-60 part, cement 10-40 part and additive 0.5-2 part;
Preferably, the weight portion of each component is: building discarded object particle 40-60 part, cement 15-30 part, additive 0.5-1.5 part;
Preferred, the weight portion of each component is: 50 parts of building discarded object particles, 25 parts of cement, 1 part of additive.
Wherein, described building discarded object particle can be cement, brick or the stripping and slicing etc. of being discarded behind the demolishing buildings, and above-mentioned discarded object is broken into the particle that particle diameter is 10-20mm, perhaps breaks into 40-80 purpose particle and promptly gets described building discarded object particle.
Described additive is mixed and is got by the ultra micro building materials efficient additive more than 3800 orders, Ultrafine Silicon Powders more than 3800 orders and the ultra micro iron powder more than 3800 orders part by weight according to 1.2: 6: 2.8; Wherein, described ultra micro building materials efficient additive is that the patent No. is a ZL200310113325.2 (notice of authorization number: the disclosed ultra micro building materials of Chinese patent CN 1268574C) efficient additive.
Another technical problem to be solved by this invention provides the method for the above-mentioned bearing bricks of preparation.
Another technical problem to be solved by this invention is achieved through the following technical solutions:
A kind of method for preparing bearing bricks comprises: take by weighing each component by following weight portion:
Building discarded object particle 30-60 part, cement 10-40 part and additive 0.5-2 part; After above each component mixed, be incorporated as the water of material gross weight 15-25%, be pressed into the brick body or the stripping and slicing of all size again according to the brick-making method of routine.
Contain ultra micro building materials efficient additive in the bearing bricks of the present invention, can effectively increase cohesive strength, make bearing bricks more closely knit, behind the ultra micro oxidation of iron powder rust joint that is contained, the intensity of brick is strengthened; Cement and Ultrafine Silicon Powders produce brilliant knot lattice, make prepared brick more closely knit, strong, and water absorption rate is little, the compressive strength height.
Bearing bricks of the present invention mainly utilizes the discarded object of building to be prepared from, both provided cost savings, pollution or influence have been alleviated behind the demolishing buildings again to greatest extent to surrounding environment caused, prepared bearing bricks meets every performance of constructional materials, can use as constructional materials with existing various bearing bricks are the same fully.After testing, the compressive strength of bearing bricks of the present invention is 7.5-10MPs, and its water absorption rate will be lower than existing clay solid brick and ordinary Portland cement stripping and slicing.
