How was the stone chosen for the building?

In the load-bearing stone masonry structure, the stone should be made of natural stone without obvious weathering. Commonly used natural stones are granite, limestone, etc. Natural stone has high compressive strength and good durability, and is mostly used in the foundation of the house and the foot part, in the mountainous area, the stone can be taken locally, so it is also commonly used to build the wall of the house with stone masonry.

Stone is divided into material stone and rubble stone according to the degree of regularity of its processed appearance.

1) Material stone: (1) The fine material stone is finely processed, the appearance is regular, the depth of the stacked masonry surface should not be greater than 10mm, the cross-sectional width and height should not be less than 200mm, and should not be less than 1 4160 of the length

2) Semi-fine stone, the size is the same as that of fine stone, but the depth of concave surface should not be greater than 15mm.

3) The size of the coarse stone is the same as that of the fine stone, but the depth of the concave surface of the stacked surface should not be greater than.

4) The shape of the wool stone is roughly square, generally not processed or only slightly trimmed, the height should not be less than 200mm, but the depth of the stacked surface should not be greater than 25mm.

2) Rubble: (1) The shape of rubble is irregular, and the thickness of the middle part should not be less than 200mm.

2) The strength grade of the stone can be expressed by the compressive strength of the cube test block with a side length of 70mm. The compressive strength is the average value of the compressive strength of the three specimens.

1) Observation. Observe the surface structure of the stone with the naked eye, the uniform fine material structure of the stone has a delicate texture, which is the best product of the stone, and the appearance quality of the coarse and unequal structure of the stone is poor.

2) Listen to the sound.

Listen to the sound of stone knocking Dense and solid stone has a crisp and pleasant sound, and if there are cracks inside, the sound is rough and hoarse.

3) Measure the size.

Measure the size and specifications of the stone The stone with better quality has small size error, less warpage and smooth surface.

Fourth, the quality of the test.

Use ink to test the quality, drop a drop of ink on the back of the stone, if it is quickly dispersed and leached, it means that the quality of the stone is not good, on the contrary, if the ink does not move in place, it means that the stone is dense and has a good texture.

Fifth, according to the color of the purchase.

Generally speaking, red symbolizes auspiciousness and beauty, yellow symbolizes light and nobility, green symbolizes hope and tranquility, black symbolizes power and dignity, and so on. Colors carry people's hopes and wishes, showing people's different aesthetics and psychological expectations.

6. Purchase according to your budget.

For the average family, choosing domestic stone can also achieve a good decorative effect. Domestic stone such as black and white root, silver white dragon, silver gray dragon, kaphoya, melintekin, California beige, Fujian granite stone, bluestone, basalt, shrimp red rust stone, hemp, tiger skin white and other varieties also have strong decoration, and even some are better than imported similar products, but ** is much cheaper.

7. Pay attention to quality indicators.

The use area of stone in home decoration is generally small, and the radioactivity of stone will not cause damage to the human body, but in order to rest assured, when buying stone, you should see if there is a safety license for radioactivity, and choose according to the radiation level of the stone.

As the name suggests, stone is a building material made from stone. There are natural stones, which are generally processed from natural granite and marble. Artificial stone is the secondary processing of stone waste, and some of the quality is also very good.
