Q:Civil engineering commonly used materials which four kinds
The first floor to answer the right, reinforced concrete gravel sand
Q:In addition to cement, but also add gelling agent
The development of cementitious materials has a long history, people use the earliest cementitious material - clay to wipe the simple building. Then there are cement and other building materials and cementitious materials have a great relationship.
Q:Read materials science and engineering or civil engineering, it is tangled ah, we discuss together!
Material science and engineering and civil engineering, the theoretical requirements of high, civil engineering practice is relatively strong. Civil engineering may be tired.
Q:What are the main features of gypsum for civil engineering materials?
Building gypsum in the water after mixing, the slurry in a few minutes began to lose plasticity, complete loss of plasticity within 30min and produce strength, about a week or so completely hardened. To meet the construction requirements, need to join the retarder, such as borax, potassium tartrate, citric acid, polyvinyl alcohol, lime activated bone glue or leather and so on.
Q:Civil engineering materials what is the toughness of the material
The inherent nature of the material varies depending on the material
Q:What are the four major mechanics in civil engineering?
You should not be civil engineering, engineering mechanics contains the theory, materials, structural mechanics knowledge, agreed to theoretical mechanics, material mechanics, structural mechanics, soil mechanics for the four major civil mechanics
Q:What is the course of civil engineering materials?
First of all, if you are studying the basic nature of the most basic civil materials (such as concrete, gravel, etc.), how these materials such as mix ratio and particle size affect their performance, as well as the details of these materials Division, after learning this has a general understanding of this.
Q:What is the civil engineering material
Do something about the civil material
Q:Material science and civil engineering which is better?
You can choose according to your hobby and your favorite area, or your own thoughts
Q:On the inorganic non-metallic materials engineering (civil materials) jobs and treatment.
This unit seems not stable, very big liquidity, not with the Project run may be better. Treatment are almost it, the general level.
