Discuss the main types of materials used in the construction. It is commonly house building company บริษัทรับสร้างบ้าน used and refers to physical properties and benefits for construction. The principles for choosing building materials are as follows:
- Each building material has unique properties such as strength, flexibility, toughness. Materials suitable for building structures are materials that combine flexibility and toughness.
- The flexibility of a material means the ability of a material to deform when subjected to bending, pulling, or compressive forces creates a unit of force within the material. But it can be restored when the force exerted from the material is removed. Each material has its own elastic rating. If the material is subjected to a force that exceeds the aforementioned elastic rating, the material will permanently deform or break.
- Plastic deformation material. Before a disaster or breakage occurs, these materials are referred to as ductile materials.
- On the contrary materials with low resilience ratings and sudden failure or breakage when applied to them. These materials are called brittle materials. This type of material is not suitable for use as a building structure.
- Toughness means the ability of a material to withstand its own elastic rating the toughness of the material including the cross-section of the material itself It is important to determine the length of the span and the body or the elephant’s belly.
- Material properties for size and shape changes when the temperature or humidity changes. It is also important to consider the choice of materials when used to contact or combine with other types of building materials.
- Water or moisture resistance of the material. It will be an important feature to consider when choosing building materials in the climate.
- Construction materials used for exterior surfaces. Conductive or insulating properties should be considered.
- Construction materials used as surface finishes of rooms in the building. The properties of transmission, reflection, light absorption and radiation should be evaluated.
- Density or strength of the material will determine the ability of that material in corrosion resistance and economical maintenance.
- Selection of materials for construction as part of the structure or interior surface of the building. Consideration should be given to its non-combustible properties, fire resistance, or when fire does not produce smoke or toxic gases.
- The designer should determine the type of material with a particular color and pattern. Including the size of the proportion according to the layout laid out.
- Most of the building materials for building houses รับสร้างบ้าน are produced in standard sizes and shapes which each manufacturer may produce differently. Therefore, the building designer should determine the style of installation or placement of building materials as detailed or as close to reality as possible in the design process. To help reduce unnecessary material wasted cutting chips during actual building construction.
- Stress is deformation of the material when the force is applied. This is equal to the ratio between the change in shape size to the original shape size before the force is applied.
Assessment and selection of construction materials for use should consider the characteristics of use, economy and beauty as well as the impact that may have on the environment. Such assessments are called “Life Cycle Assessment” which covers from raw material acquisition production process packing of products and transporting materials to the construction site. Maintenance of the material during use, the opportunity to reuse the material again. As well as the elimination of this assessment process consists of three parts: the introduction of raw materials, production cycle list and use of materials and waste.
- The energy value within the material is the total energy consumed over the lifespan of the material.

acquisition of raw materials
Production process and product packaging
Transportation and distribution of products
disposal and reuse
- What are the effects of the acquisition of raw materials on human health and the environment?
- Can the material be reused?
- Raw materials or resources that cannot be renewed to replace the old ones, such as metals and minerals.
- A type of raw material or resource that can be renewed to replace the old one, such as wood, which has a period of replacement. Depending on the growth rate of each type of wood, therefore the acquisition of raw materials or the cutting rate of trees should not exceed the growth rate of the tree.
- How much energy and water will be required to produce? product packing or building materials
- Construction, use and maintenance of the product.
- Can I buy local products or building materials? or must be imported from abroad
- Can the material be used effectively for its intended purpose?
- How will the material affect the indoor climate and the energy wasted inside the building?
- How durable is the material or product and how much maintenance or maintenance is required?
- How long does the material last?
- Applicable materials.
- The amount of waste and toxic substances generated from the production and use of materials or how many products
- Waste water or waste that must be discharged into the sewer.
- Smoke released into the air.
- solid waste
- Other forms of waste released into the environment.
Production cycle and material usage list
Evaluation and selection of building materials is a complex matter. There is no formula for determining exact and accurate alternatives, for example using materials with low internal energy values may save energy work and natural resources rather than the use of materials with high internal energy. But using materials with high internal energy values are more durable and less maintenance than materials with low internal energy values. Alternatively, the use of materials that can be recycled may be more attractive than those with low internal energy, for example.
Reducing the use of new, bruised, and reused items. It will play an important role in helping to ensure consistent use of raw materials and sustaining resources to replace the used parts in a timely manner with the following methods.
- Reduce the size of the building for efficient use.
- Reduce the amount of waste generated from construction: Refer to the Environmental Friendly Standard for Materials and Resources Section 2, Waste Management.
- Efficiently identify materials made from natural raw materials: refer to environmentally friendly standards. Materials and Resources Section 5 Local Materials
- Try to use materials produced from abundant natural resources. Substituting materials produced from scarce or scarce natural resources: Refer to the Environmental Friendly Standard for Materials and Resources Section 6, Renewable Materials.
- Recycle scrap or demolished materials from old buildings: refer to environmentally friendly standards. Materials and Resources Section 3 Recycling of used materials
- Renovate existing buildings instead of building new ones: Refer to the environmental friendliness standard for materials and resources, Section 1, the use of existing buildings.
- Recycle old and used materials: reference to environmentally friendly standards. Materials and Resources Section 3 Recycling of used materials
