Embodiment 1

[0018] Example 1: Clay from a county in Hebei, ordinary Portland cement, natural sand with a particle size of 0.15-4.75 mm, and gravel with a particle size of 2.36-9.5 mm were selected. Concrete is made by mixing 50kg of cement, 100kg of natural sand, 125kg of gravel and adding 30kg of water.

[0019] Using the above-mentioned preparation process, a NF building block (240×115×53 mm in size) with a concrete layer thickness of 1 cm was manufactured. According to the test method of GB / T2542 wall bricks, the strength level of the blocks obtained in this embodiment reaches MU30 after testing.

Embodiment 2

[0020] Embodiment 2: Select clay, ordinary Portland cement, medium sand, and gravel with a particle size of 2.36-9.5 mm from a certain county in Hebei. Concrete is made by mixing 40kg of cement, 125kg of medium sand, 100kg of gravel and adding 20kg of water.

[0021] Using the above preparation process, NF blocks with a concrete layer thickness of 2.0 cm were manufactured. After testing, the strength level of the block obtained in this embodiment reaches MU30.

Embodiment 3

[0022] Embodiment 3: Select clay, ordinary Portland cement, medium sand, and gravel with a particle size of 2.36-9.5mm from a certain county in Hebei. Concrete is made by mixing 60kg of cement, 75kg of medium sand, 150kg of gravel and 40kg of water.

[0023] By adopting the above-mentioned preparation process, NF blocks with a concrete layer thickness of 2.5 cm were manufactured. After testing, the strength level of the block obtained in this embodiment reaches MU30.

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 [0001] The invention relates to a building material, in particular to a fire-free cored earth block and a preparation method thereof. Background technique [0002] At present, my country has a population of 1.3 billion, most of whom live in rural areas. Nowadays, bricks or concrete are mostly used as blocks for building houses in rural areas. Houses built with bricks have the disadvantage of short service life because they are not resistant to rain, wind erosion, etc. Concrete houses are more expensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-cost, durable non-burning cored clay block and a preparation method thereof. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: the outside of the square earth block is coated with a concrete layer. [0005] The preparation process of the present invention is as foll...
