What are the main materials in the building?
It determines the building's rugged, durable, applicable, economical and beautiful. Building materials accounted for more than 60% of the total project fee. It is necessary to study the raw materials, composition, structure and characteristics of various materials in order to rationally select and correctly use the building materials.
Building materials of the same product is often divided into several grades and labels. Each grade of material should ensure a certain quality, which is the material standard. In the material standard specifies the material specifications, size, fineness, chemical composition, strength, technical indicators. Materials in the factory, after acceptance and use should be sampled to see if it meets the standard.
Portland cement in Europe is called Portland cement, because it is the color of the cement stone with water, and the color of limestone produced in Portland. China called it Portland cement, from the name can be learned, its main component is calcium silicate. Portland cement is the main raw material of limestone, clay and iron ore powder.
Depending on the role of the material in the building, the building material can be divided into two categories: the first is the use of materials for load-bearing structures such as brick, stone, concrete, mortar, steel and wood. The second category is a special purpose materials, such as sound-absorbing panels, refractory bricks, antirust paint, foam glass, colored cement. Building materials are the material basis of construction
According to its performance building materials can be divided into inorganic materials, organic materials and composite materials. Inorganic materials are divided into metal and non-metallic materials. Organic materials are natural and synthetic
