Problems solved by technology

[0004] However, the strength of the existing blocks is slightly insufficient, especially on the surface, which is prone to cracking under pressure, resulting in a further decline in strength and impermeability, and is prone to appear at the joints between blocks during actual use. water seepage phenomenon, and it is difficult to have an effective method in the prior art

Embodiment 1

[0045] see figure 1 , a pre-embedded concrete block forming process, comprising the following steps:

[0046] S1, weigh the following raw materials according to parts by weight: 20-50 parts of cement, 5-10 parts of slag powder, 4-8 parts of fly ash, 10-15 parts of crushed stone, 15-20 parts of quicklime, 10-15 parts of water parts and 1-5 parts of waterproofing agent;

[0047] S2. After mixing and stirring the above-mentioned raw materials evenly, a slurry is obtained, and a pre-embedded mold is prepared, and a plurality of evenly distributed pre-embedded sinkers are pre-adsorbed in its inner side;

[0048] S3. The slurry is poured into the embedded mold, and then pressed to obtain a semi-finished product, and the semi-finished product is subjected to steam curing;

[0049] S4. After the maintenance, take out the semi-finished product, and separate the part of the pre-embedded sinker extending out of the semi-finished product for recycling;

[0050] S5. Polish the surface o...

Embodiment 2

[0062] The rest of the parts are the same as those in Example 1. The difference is that the adsorption hemisphere 5 is made of a ferromagnetic material, and a corresponding magnetic layer is provided on the inner top of the upper mold 1 to adsorb the adsorption hemisphere 5. After cooling down, remove the formwork and take out the block. At this time, the sensing hemisphere 3 and the adsorption hemisphere 5 are not separated. The anti-seepage powder can be protected to prevent leakage during transportation, and the sensing hemisphere can be separated by temporary heating at the construction site. Although the hemisphere 3 and the adsorption hemisphere 5 are troublesome in operation, they can ensure the integrity of the anti-seepage powder.

[0063] The invention can realize that when the block is formed, a plurality of pre-embedded sinkers can be adhered to the pre-embedded mold in advance, and then the mixed concrete slurry is poured into the mold for forming. At this time, th...

Abstract

The invention discloses a pre-embedded concrete block forming process, belongs to the technical field of concrete processing, and can realize that when a block is formed, a plurality of pre-embedded pendants are adhered in a pre-embedded mold in advance, then mixed concrete slurry is poured into the mold for forming, and at the moment, the pre-embedded pendants can be uniformly pre-embedded at the upper end of the block; then, the embedded pendant is unlocked by utilizing high temperature during steam curing, so that the upper surface of the building block is kept flat, the embedded pendant is completely embedded in the building block after the building block is taken out after the mold is removed, the strength of the building block, especially the near surface, can be improved in the using process, and when a water seepage phenomenon occurs at the joint of the building block, the building block is prevented from falling off. The anti-permeability of the building block can be improved by utilizing the self-reaction of the embedded pendant, and further permeation of water is prevented, so that the safety of the concrete building block during use is improved.

Description

technical field [0001] The invention relates to the technical field of concrete processing, and more particularly, to a pre-embedded concrete block forming process. Background technique [0002] Concrete usually uses cement as cementitious material, sand and stone as aggregates, mixed with water and admixtures in a certain proportion, and then mixed to obtain concrete. Concrete has the advantages of easy molding, low energy consumption, and low price. It is widely used in architecture and plays a very important role in the development of human society. [0003] A block is a blocky building product larger than a clay brick. Its raw materials come from a wide range of sources and varieties, which can be obtained locally and at low prices. According to the size, it is divided into three categories: large, medium and small. China mainly produces small and medium-sized blocks. Those with a block height of 380-940mm are medium-sized; those with a block height of less than 380m...
