Classification of building materials. why building materials are required?

 

Preface

 This chapter focuses on the groups and the specialized norms of structure accoutrements ; it summarizes the characteristics of structure accoutrements and  their status in construction engineering briefly; and also it introduces the development of structure accoutrements .

 Delineations and groups of structure
 Accoutrements

 In the general terrain for humans ’ survival, all the accoutrements or products

 used in structures or structures are called structure accoutrements which are the

 material foundation for all the construction engineering. The structure

 accoutrements bandied in this course are all the accoutrements used in erecting

 foundations, bases, bottoms, walls, shafts, plates, roofs and architectural

 decoration.

 There's a wide variety of structure accoutrements . They're generally classified

 from different angles for the sake of study, operation and description. The

 most common groups are grounded on their chemical factors and

 functions.

Stone material 

 

 1) According to the chemical factors of structure accoutrements , they can be

 classified into inorganic accoutrements , organic accoutrements and compound accoutrements ,

 as follows

 Metal Steel, Iron, Aluminum, Bobby, colorful Types of blends

 Metalloid Natural Stone. Cement, Concrete, Glass, Uurncd Soil Products,etc.

 Mctal- metalloid Composition Reinforced Concrete,etc.

 Inorganic

 Accoutrements

 Wood, Plastics, Synthetic Rubber, Petroleum Asphalt.etc.

 Inovic MetalQganic Cornpsition Polymer Concrete, Fiberglass

 Reinforced Plastics,etc.

 Metal- Organic Composition Light Metal Sandwich Panels, ctc.

 2) According to the functions of accoutrements , they can be divided into
 structural accoutrements and functional accoutrements

 Structural Accoutrements substantially used as cargo- bearing members, similar as the

 accoutrements used for shafts, plates and columns.

 Functional Accoutrements substantially enjoying some special functions in

 construction, similar as leakproof, cosmetic and heat- separating functions,

etc.

 

 Status in Architecture
 

 Characteristics of structure Accoutrements and Their

 structure matcrials are the material foundation for all the construction

 engineering. structure accoutrements assiduity which is one of the important introductory

 diligence of public frugality promotes the development of the construction

 assiduity.

 

 Colorful structures and structures are constructed by all kinds of erecting

 accoutrements on the base of reasonable design. The kinds, specifications and

 rates of structure accoutrements are directly related to the connection, art

 and continuity of structures and also to the cost of systems. A large ncmber of

 high- quality artificial and civil structures need to be erected for the development

 of society. Meanwhile, a great deal of water sustentation systems, business

 engineering and harborage systems need to be erected to acclimatize to the rapid-fire

 development of the public frugality. It requires lots of high- quality structure

 accoutrements which accords with the operation terrain of systems.

 thus, erecting accoutrements assiduity is generally considered as the introductory

 assiduity for the construction engineering.

 

 Structure accoutrements not only have a large consumption, but also are

 precious. In the total cost of the construction, the cost of structure accoutrements

 frequently accounts for about 50 percent. therefore, it's significant to duly choose

 and nicely use structure accoutrements in the construction for the reduction

 of costs and the enhancement of investment benefits.

Timber material

 

 A large number of new structure accoutrements continue to crop , frequently

 promoting the invention and development of construction ways. For

 illustration, the emergence of complexion bricks contributes to the slipup- timber

 structure; the corroborated concrete structure comes from concrete and sword bar;

 light high- strength accoutrements promote the development of modem structures

 1 preface 3  and high- rise structures; the operation of colorful functional accoutrements in the

 Construction assiduity continues to produce diversified   comfortable living and
 product terrain and to conserve energy.

 

 In short, the operation of structure accoutrements in the systems must retain

 the ensuing characteristics the function needed by systems, the continuity

 proper for the environmental conditions, the rich coffers to meet the requirements

 of construction, and low price.

 In the structure terrain, the ideal structure accoutrements should be light,

 high- strength, aesthetic, heat- separating, sound- absorbing, leakproof,

 shockproof, incombustible,non-toxic, and effective,etc.
