Product Description:

Concrete block and reinforced protective layer block, is in the masonry structure and frame structure, under the beam, to expand the confined area, reinforced position, to prevent corrosion of steel exposed and the function.

Is a solution to the often used local pressure. 

Reinforced concrete cover thickness is related to the bearing capacity and durability of the structure, the function such as fire prevention. Has the following role and influence of reinforced concrete guard-layer:

1, maintenance structure durability of concrete protective layer is too thin to penetrate in the wet gas and water, too thick, easy to produce cracks, these could make the steel corrosion and inflation, so that the destruction of a concrete influence use and security of structure.

2, under external force Protection layer for steel bar anchoring force, takes advantage of the anchoring force between concrete and reinforcing steel bar, the two together, jointly participate in the work. Protective layer too thin or missing, reduce its anchorage force which reduces the structure to withstand the axial force and bending moment.

3, from the calculation formula of flexural bearing capacity of normal section

M a l or less FCBX (h0 x / 2) + fy 'AS' (ho - a s') a (sigma pO 'a fpy) a p' (ho - a p '), you can see that when the gluten protective layer through the thick section effectively reduced height h0, will reduce the cross section flexural bearing capacity. Visible protective layer thickness is how important factor affecting bearing capacity of structure.

4, fire protection layer of concrete has a certain thermal insulation effect, can more easily to soften when you encounter fire reinforced protection, if too thin, protective layer thickness under the environment of high temperature easy craze, cause reinforced in overheating and reduce the strength to destroy the whole structure. Hunan hengyang in 2003 a project is due to the high temperature heat from the burning of fire to soften steel lead to collapse and cause heavy casualties accident.

In the quality inspection of the current work, therefore, more attention paid to the protection layer thickness control, new rules to entities in the process of acceptance testing.

Q:What is the relationship between the development of civil engineering and the material and the theory?
There are three major mechanics in civil engineering; theoretical mechanics; material mechanics; structural mechanics. The discovery of mechanics has also reduced the cost of engineering.
Q:Why beginners or senior civil engineering and technical personnel are required to continue to learn civil engineering materials
Urban development is much faster than mass maternity leave
Q:Material in the role of civil engineering in which should be the main understanding
4, some materials may need to re-examination, the need for timely submission of materials, and with the approach material corresponding. 5, for the emergence of the scene material loss, the need for material to be reported in a timely manner.
Q:What is a civil engineering material?
From the narrow sense of the definition, civil engineering is equivalent to civil engineering, that is, construction (or structural engineering) this small range.
Q:Detailed classification of civil works?
Civil engineering is generally divided into civil engineering, geotechnical professional, water supply and drainage professional. Different schools will have their own different professional classification.
Q:What are the three mechanics of civil engineering?
Main structure materials mechanics, structural mechanics, fluid mechanics, soil mechanics, building materials, concrete structure and steel structure, housing structure, bridge structure, underground structure, road survey design and roadbed structure, construction technology and management.
Q:Which version of the material mechanics (author) is suitable for civil engineering this profession?
Structural mechanics, "structural mechanics", "river dynamics", "geotechnical principles", "soil mechanics and environmental geology", "steel", "elasticity theory", "elastic theory" (upper and lower volumes) Structure of the basic principles "(second edition)
Q:I am now reading materials science and engineering,then you can report civil engineering professional?
You are cross-professional, the teacher will not like, in the school should also pay attention to. If the election hook the direction of what, it is best not to report a good school. Re-test time will be affected. General school can still be considered.
Q:What is the civil engineering material
Some material shopping guide
Q:University of high polymer materials or civil engineering
Can say that civil engineering is the most suitable for the two students to learn, because the country year after year to increase infrastructure construction, the civil engineering talent is extremely necessary
