1. What is the specific gravity of the stone?

1. Because there are many classifications of stones, such as sand, gravel, pebbles, etc., the specific gravity of different stones will be different. If it is a coarse stone, the specific gravity per cubic meter is 1550 kilograms. The specific gravity of medium sand is 1550 kilograms per cubic meter, the specific gravity of fine sand is 1400 kilograms per cubic meter, there is a kind of sand and gravel, its specific gravity is 1550 kilograms per cubic meter, and the gravel is close to this, about 1500 kilograms per cubic meter.

2. Whether it is sand, gravel or pebbles, its main component is silica, and the density of silica will determine their specific gravity. It is also directly related to the bulk density, if the more dense the pile, the greater the density, and at the same time, the good allocation of sand and gravel will also increase the bulk density.

The above content is specifically about the specific gravity of the stone, that is, its density, according to the different densities, the size of the particle size is different, and the weight of different types of stones is also different.

The specific gravity of recycled stone is not much different from the specific gravity of stone.

The weight of the stone is 2200kg m3

Reinforcement: 65 70kg m2

Concrete: 7. Villas: the amount of concrete and steel is between multi-storey masonry houses and high-rise 11 and 12 floors;

The above data are designed according to the regular structure of the seismic 7-degree zone.

2. Economic indicators of construction budget for ordinary multi-storey residential buildings.

1. The area of outdoor doors and windows (excluding unit doors and anti-theft doors) accounts for the construction area 2, and the template area accounts for about the construction area.

3. The outdoor plastering area accounts for about the construction area.

4. The indoor plastering area accounts for the construction area.

Third, the construction effect.

1. A plasterer plasters 35 square meters a day.

2. A bricklayer lays 1000 1800 red bricks a day 3, a bricklayer lays 800 1000 hollow bricks a day 4, and tiles are 15 square meters.

5. The first time to scrape the white is 300 square meters a day, the second time is 180 square meters a day, and the third time is a 90 square meter day.

Fourth, basic data.

1. The weight of concrete is 2500kg m3

2. The weight of the steel bar per linear meter.

3. The weight of dry sand is 1500kg m3, the weight of green sand is 1700kg m34, and the weight of stones is 2200kg m3

5. About 525 red bricks per cubic meter (wall thickness).

6. There are about 175 hollow bricks per cubic meter.

7. Sieve one side of clean sand needs side of ordinary sand.

Summary. Hello dear! Probably in.

Qualified ordinary dry stone powder is 1400-1550 kg cubic meters. There are many types of stones, and there are many varieties according to the mineral composition, and it is not necessarily calcium carbonate. Calcium carbonate is limestone, just one of the stone powders, and there is also talcum powder in the stone powder, which is used to make putty.

There is also quartz powder, which is used to make glass. There are also many mineral rocks that can be ground into powder and used in different processes and applications. Extended InformationStone powder has a wide range of uses, and the products made from it are ubiquitous in our lives, such as:

Plastics, calcium tablets, cosmetics, clothes, toothpaste, etc. Ultrafine stone powder: widely used in rubber, papermaking, coatings, plastic aluminum profiles, ceramics, cement, glass, smelting, refractories, medicine, food, daily chemicals, cosmetics, craft construction, advanced decoration and other production applications.

Especially when applied to coatings and papermaking, it can directly reduce the amount of titanium dioxide used by 3%-10%, thereby greatly reducing the cost of products. High-quality white marble (dolomite) ultra-fine stone powder is used in pulp compounding (coated paper, coated paper, etc.), and its role is to increase opacity and improve paper flexibility.

What is the reason for the low specific gravity of stone powder.

Hello dear! Probably in. Qualified ordinary dry stone powder is 1400-1550 kg cubic meters.

There are many types of stones, and there are many varieties according to the mineral composition, and it is not necessarily calcium carbonate. Calcium carbonate is the limestone of Shihuai Town, which is just one of the stone powders, and there is also talcum powder in the stone powder, which is used to make putty. There is also quartz powder, which is used to make glass.

Hello, dear. The fine stone content in the stone powder is . Converted into SO3, by mass, %) in the case of fine stone powder as a carrier and diluent, the particle size of about 90% is less than better, and the sulfide and sulfate content of crushed stone or pebbles (converted into SO3, by mass, %) The organic matter content in the pebble (tested by colorimetric method) The color should not be darker than the standard color; Gravel or pebbles should be tested for alkaline activity; The alkali content in concrete does not exceed 3kg m3.

The mud content of crushed stone or pebbles is non-clay stone powder, and its mixed content is ; 1.The content of organic matter in the pebble (tested by colorimetric method) The color should not be darker than the standard color, when the color is darker than the standard color, it should be prepared into concrete for strength comparison test, and the anti-dust compressive strength ratio should not be lower than that of Zen. When crushed stone or pebbles contain granular sulfate or sulfide impurities, special inspection should be carried out to confirm that it can meet the durability requirements of concrete before it can be used.

2.For important structural concrete that has been in a humid environment for a long time, the crushed stone or pebbles used should be tested for alkali activity. When carrying out alkali activity testing, the petrographic method should first be used to test the variety, type and quantity of alkali active aggregates.

When it is found that the aggregate contains active silica, the rapid mortar method and the mortar length method should be used for alkali activity testing. When the aggregate is found to contain active carbonate, the rock column method should be used for alkali activity testing. After the above test, when it is determined that the aggregate has the potential alkali-carbonate reaction to harm dry pants, it should not be used as concrete aggregate, otherwise, it should pass a special concrete test and make the final assessment. When it is determined that the aggregate has a potential alkali-silicon reaction hazard, the alkali content in the concrete should be controlled not to exceed 3kg m3, or effective measures should be adopted to inhibit the alkali-aggregate reaction.

3.The mud content of crushed stone or pebbles includes non-clay stone powder in crushed stone or pebbles, and its mixing content. Dear, <>
