Building Materials And Their Specifications

The construction components should meet the requirements for maintainability and safety limits. One of the most important safety requirements in architectural design is to provide adequate fire resistance for various components.

Mechanical properties: Concrete is a very pressure-resistant material, but its tensile strength is very low. The tensile fiber must, therefore, be reinforced. They are bulky, rigid structures with few vibration problems and have integral connections. Fragile cutting and twisting. There are a number of Building materials online websites. You can order from the website and get it to deliver on your doorstep.

Ductility: Compared to steel and wood, their ductility is poor, and some degree of ductility must be considered in the design to construct the element in the area of ​​excessive stretch.

Structure method: The components of the concrete structure can be prefabricated or cast on site. A template is required for emptying on-site.

Benefits: They have frequently used constructions with high resistance to internal work, in particular compression, low work qualification, good fire resistance, few vibration problems, the size of components and non-load-bearing components, and almost no maintenance is required. Building materials online have high-strength storm protection and long-term durability.

Drawbacks: Bulky structure and large volume, large light leads to a large size and high cost of the component, cracks are inevitable, and the template wastes time and money, so that good quality control must be maintained.

Fire resistance: Good fire resistance (1 to 3 hours of resistance). It is fireproof than wood and structural steel.

Permanence: Over time, long-lasting structures typically do not require significant economic investments for maintenance. They have a long lifespan.

The energy used to make concrete is not as good as steel. Today’s technological advances have reduced the production of carbon dioxide in the cement industry.

Mechanical steel

Automatic properties: Steel is a highly ductile material. They are light structures with high tensile strength and steel has uniformity and homogeneity. High heat and conductivity. One of the most important tests to be performed are vibrations and arrows.

Extensibility: Extremely high extensibility.

Benefits: It can cover headlights, fast construction, materials with high ductility, optimized cross-section and light structure. Its properties do not change over time, it is very easy to connect elements, has excellent laminas ability, fatigue resistance and can be disassembled and reused.

Drawbacks: deformation of large components, vibration problems, poor fire resistance, sensitive connections, limited profile transport, corrosion problems, high maintenance costs and high energy consumption.

Fire resistance: Steel has a false sense of security because it is not easy to burn, but its basic mechanical properties are seriously affected by the high temperature curve that can be achieved during the fire.

Permanence: They require maintenance and adverse environments can be extremely corrosive.

Sustainability: Steel is often seen as a material for “friends of the environment”, mainly because of its recycling potential. Nevertheless, the production of steel components still requires a lot of energy and high carbon dioxide emissions.

Wood construction

Mechanical properties: In contrast to most structural materials, it has a higher tensile strength than the compressive strength, although the latter is also acceptable. The material is very anisotropic. The structural properties of wood vary greatly depending on the type and possible defects of a particular component.

Ductility: One of the most important properties of wood structures is that they have high ductility, i.e. they can deform further without breaking under the action of the force.

Benefits: It has a high compressive and tensile strength, a fast construction speed, less energy than steel components, good availability as well as thermal and electrical insulation.

Drawbacks: There are problems with water and high humidity, poor behavior in the presence of fire and problems with termites.

Earthquake safety: Light material, flexibility, low modulus of elasticity, high cycle, low acceleration. It is a fragile linear elastic material until it breaks. It offers ductility through metal connections. The short-term load resistance is greater. The R coefficient depends on the construction system, its redundancy and the type of connection.

Fire resistance: From the point of view of material performance, wood is a combustible material. Whether as a material or a tough element, we can use products, treatments, or suitable construction details to improve performance.

The holes in the wood make it difficult for heat to pass through, make it a good thermal insulation material and can also prevent the fire from going out if the wooden beam is thick. Given the noise, the insulation performance is poor, especially when compared to other more effective materials. Dry wood is a good electrical insulator. When the air humidity increases, its specific resistance quickly drops.
