Q:Questions about civil engineering materials
First, with excellent adhesion, construction, anti-droop, so that the formation of waterproof between the continuum; second, with good flexibility, can withstand structural parts due to temperature, humidity, wind, earthquake And so on caused by the seam deformation; Third, with weather resistance, water resistance, long-term outdoor sunshine, rain, snow and summer heat and other conditions under the effect of maintaining long-term adhesion and tensile compression performance.
Q:architecture material
The technical requirements of these three kinds of cement are basically the same, the technical requirements are as follows: 1. Magnesium oxide: clinker in the magnesium oxide content of not more than 5%. 2. Sulfur trioxide: slag cement in the content of sulfur trioxide shall not exceed 4.0%; mountain cement, fly ash cement sulfur dioxide shall not exceed 3.5%. 3. Fineness: 80μm square hole screen sieve should not exceed 10.0%. 4. Coagulation time: the initial condensate not as early as 45min, the final condensate no later than 10h. 5. Stability: must be qualified by boiling test.
Q:Civil engineering materials, what kind of
Generally classify the various classification methods by appropriate combination of materials after the division. Such as decorative mortar, asphalt waterproof material.
Q:Civil engineering commonly used materials which four kinds
The first floor to answer the right, reinforced concrete gravel sand
Q:What is civil engineering and architecture?
Two professional comparison in the design industry is most obvious, is two professional called architecture and structural professional. The former concept of the program, consider the function and layout, which consider the internal reinforcement and other structural problems, to achieve the former concept, both with water, warm, electricity professional to complete a project design.
Q:On the Title of Civil Engineering
I am learning materials (material molding), but I now work in the construction unit, or civil engineering is good, (their own feelings) good job opportunities, work is also good treatment.
Q:Is the glass made of wood?
Glass is not civil material!
Q:Civil Engineering Materials.
Civil Engineering Materials. e Material saturated with water, and then dry the surface, is the hole filled with water or closed hole filled with water? What is the condition of putting the material in a jar filled with water? Not to say that the closed hole is not water?
Q:Civil engineering materials on the prospects for talent employment, a little more
The key is to see what you are interested in what the current development of the chef industry quite good, chef technology to worry about can not find a job, when not you find a job but work to find you, learn professional chef technology to choose Professional schools, mainly to see their teaching quality and campus environment.
Q:Are building materials the same as civil engineering materials?
Should be almost the same, my class textbooks are civil engineering materials, class name building materials
