What is a small hairy stone? The difference between rough stone and wool stone

Rubble is an unformed stone that is in its natural state after mining. It is an irregularly shaped stone obtained after the rock has been blasted or manually excavated, the irregular shape is called rubble, and the one with two roughly parallel planes is called flat rubble.

Miscellaneous rocks that are in their natural state after mining, or have not been graded.

1. Rubble. Rubble refers to irregularly shaped stones that have been mined and unprocessed. Rubble is mainly used for building foundations, corners, walls, retaining walls, embankments and slope protection, and can also be used to pour flake concrete.

2. Wool stone.

Material stone refers to the hexahedral block stone that is manually chiseled or machined and has a relatively regular shape. According to the degree of surface processing flatness, it is divided into four types: wool stone; coarse stone; semi-fine stone; Fine-grained stone.

If it is divided into strip stone, ashlar stone, arch stone (wedge-shaped) according to the shape. The material stone is mainly used for the foundation, legging, wall and other parts of the building, and the half-year-old bucket fine stone and fine stone are mainly used as facing materials.

Wool stone: the appearance is roughly square, generally not processed or slightly adjusted. The width and thickness of the material stone should not be less than 200mm of dust height, and the length should not be more than 4 times of the thickness. The surface recessing depth of the stacked surface and the joint surface is not more than 25mm, and the compressive strength is not less than 30MPa;

What is rubble concrete rubble concrete is to add rubble blocks to the concrete when pouring concrete, generally plain concrete plus rubble blocks.

Affinity stone is generally used for foundation engineering more, add a certain amount of rubble when pouring concrete, can be used to make rubble concrete wall.

With the development of China's modernization, light steel keel is widely used in hotels, terminals, car transport stations, Cheling orange stations, playgrounds, shopping malls, factories, office buildings, old building renovation, interior decoration settings, ceilings and other places. Light steel (painted) keel ceiling has the advantages of light weight, high strength, adaptability to anti-ruler orange water, shockproof, dustproof, sound insulation, sound absorption, constant temperature, etc., and also has the advantages of short construction period and simple construction.

The above is the introduction of light steel keel and rubble.

Rubble is an irregularly shaped stone that is obtained directly after blasting in a quarry.

According to the flatness of its surface, it is divided into two categories: rubble and flatstone.

Rubble stone for construction generally requires that the thickness of the middle part of the stone is not less than 150mm, the length is 300 400mm, the mass is about 20 30kg, its strength should not be less than 10MPa, and the softening coefficient should not be less than.

It is often used for masonry foundation and foot strangulation.

Walls, embankments, retaining walls.

etc., can also be prepared flake stone concrete, etc.
