Abstract
The invention discloses a baking-free core-wrapped clay building block. The structure of the building block is as follows: the concrete layer is covered outside the square clay block. The invention also discloses a process for manufacturing the baking-free core-wrapped clay building block, wherein the manufacture process is as follows: (1) clay or sand soil is stirred with water to be muddy, and subjected to forming by a mould of forming clay block so as to obtain the forming clay block; (2) a concrete layer is spread at the bottom of the finishing mould, the forming clay block is placed on the upper-middle part of the concrete layer, concrete is filled in the mould and tightly pressed and stands for 0.5 to 1.5h, and then the finished mould is removed and the forming building block is obtained; (3) the forming building block is dried to obtain the finished product. The building block has the advantages of low manufacturing cost, wind erosion resistant, rain protection and durability; particularly, the building block is applied to low storied dwellings built in rural areas; moreover, the building block is high in strength, and the dimension of the building block can be adjusted in the process of manufacturing according to actual demand, so that the building block is widely applied to vast rural areas.
Description
Technical field
The present invention relates to a kind of material of construction, especially a kind of baking-free core mud building blocks and preparation method thereof.
Background technology
There are 1,300,000,000 populations in China at present, and wherein major part is lived in the rural area.The building block of using when now, build a house in the rural area is many with brick or concrete.With brick house,, there is short shortcoming duration of service because of not rain resistance, wind erosion etc.And with the house of concrete placement, cost is higher.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of cheap, long-lived baking-free core mud building blocks and preparation method thereof.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the external packets at square earth piece is covered with concrete layer.
Preparation technology of the present invention is: (1), blunge into the mud shape with clay or sandy soil with the mould molding of moulding earth piece, obtains the earth piece of moulding;
(2), at finished product mold bottom tiling one deck concrete layer, the earth piece of moulding is placed on middle part on the concrete layer, penetration concrete in mould, removes the finishing die tool after placing 0.5-1.5h at compacting, obtains shaping building block;
(3), above-mentioned shaping building block is dried promptly obtain finished product.
Adopt the beneficial effect that technique scheme produced to be: the present invention utilizes the existing earth in rural area as main raw material, and is cheap, only is equivalent to the rural area with 1/2nd of common brick, can extensively promote in the Rural areas.The present invention coats concrete layer in the outside of earth piece, make it the characteristic that has weatherproof, drench with rain, and is durable in use, is particularly useful for the rural area and builds low-rise dwelling.The present invention is for solid construction and bind solidly, and intensity is higher, is significantly improved on resistance to pressure, crash resistance and shock resistance than common hollow brick.The present invention can adjust the size of its size according to actual needs in making processes, the scope of application is wider.
