Description

technical field

[0001] The invention relates to the field of mining stone technology, in particular to a block repair agent, its application, and a method for repairing blocks. Background technique

[0002] Blocks refer to the processed stones from mines, which have certain specifications and can meet the needs of plate processing or other purposes. Block is not only a product of stone mines, but also a raw material for plate processing plants. Due to the weathering of hundreds of millions of years and the change of geological structure, the growth rate of blocks is low, and the mineable volume is generally 10% to 30%. Among them, more than 70% of the stones are discarded as waste due to damage. In addition, in the process of transporting blocks, the blocks will be damaged due to various factors and cannot be cut, resulting in greater losses. Due to the low yield of blocks, the cost of mining blocks is very high, and even the low yield of blocks may lead to tens of million...

Examples

Embodiment 1

[0043] The block repair agent provided in this example mainly repairs granite, and it is mainly made of the following raw materials, in parts by weight, 800 parts of No. 425 white Portland cement, and 600 parts of silica fume with a silicon content of 90 wt%. , 25 parts of lignosulfonate superplasticizer, 300 parts of water and 1 part of carboxymethyl cellulose.

[0044] In this embodiment, the block is broken into three small pieces, and the method for repairing the block with the above-mentioned block repair agent includes the following steps:

[0045] a. According to the ratio, mix the raw materials to obtain the block repair agent;

[0046] b. Apply the block repair agent to the damaged parts of the small materials, then connect and combine the three small materials, and use the wire tensioner to lock the combined blocks of the small materials, and then use the vibrator to vibrate the blocks, Squeeze out the excess repair agent in the repaired part of the block;

Embodiment 2

[0049] The block repair agent provided in this embodiment mainly repairs marble, and it is mainly made of the following raw materials, in parts by weight, 1200 parts of colored Portland cement, 200 parts of quartz powder, and silicon with a silicon content of 92wt%. 650 parts of ash, 35 parts of naphthalenesulfonate superplasticizer, 400 parts of water, 2 parts of water glass, 120 parts of ettringite expansion agent, 22 parts of vinyl acetate and ethylene copolymer rubber powder, 2 parts of carbon black, iron oxide 2.5 parts of red and 0.5 parts of iron yellow.

[0050] In this embodiment, the broken part of the block is in the middle, and there is a gap of 4 cm. The width of the gap is uneven, and the middle part is narrower, about 2 cm. The method for repairing the block with the above-mentioned block repair agent includes the following steps:

[0051] a. According to the ratio, mix the raw materials to obtain the block repair agent;

[0052] b. First insert an iron nail at...

Embodiment 3

[0055] The block repair agent provided in this embodiment mainly repairs marble, and it is mainly made of the following raw materials, in parts by weight, mainly made of the following raw materials, in parts by weight, No. 425 white Portland cement 1000 200 parts of quartz powder, 300 parts of silica fume with a silicon content of 95 wt%, 300 parts of silicon micropowder with a particle size below 2 μm, 30 parts of sulfamate superplasticizer, 350 parts of water, 2 parts of water glass, 110 parts of ettringite expansion agent, 20 parts of acrylate and styrene copolymer rubber powder, 900 parts of crushed stone with a particle size below 2cm, 0.8 parts of carbon black, 1 part of iron oxide red and 1.2 parts of lead chrome yellow.

[0056] In this embodiment, the broken part of the block is its periphery, and there are holes and depressions. The method for repairing the block with the above-mentioned block repair agent includes the following steps:

[0057] a. According to the ra...
