土木材料（Civil material） Civil engineering materials review questions A fill in the blank. The 1 main components, asphalt oil, resin and asphaltene. 2, according to the material composition of different waterproofing materials, divided into oxidized asphalt membrane, polymer modified asphalt membrane, synthetic polymer membranes. 3, low carbon steel by straightening to damage through elastic, yielding, hardening, necking in four stages. 4, plastering mortar and masonry mortar, the main technical requirements of strength and workability but not. The main role of the 5, lime paste and slaked lime in the mortar the mortar has good workability, so also known as admixture. 6, the concrete strength grade is C30, the compressive strength of the standard value of 30MP. 7, the heat of hydration of Portland cement is produced by aluminum acid three calcium and three calcium silicate, calcium aluminate in which three maximum hydration heat. 8, resistance to penetration property known as impermeability, said its size available coefficient of permeability, anti permeability level can also be said. Standard size 9, fired brick 240 mm *115 mm *53 mm, if you plan to use the brick masonry masonry 10M3 about 5120. The hydrophilicity and hydrophobicity of 10. materials (wetting edges) to represent the hygroscopic materials used (water content) to express. Absorbent materials used (water absorption) to express. The 2. volume is the hardening of gypsum (swelling) after hardening, the porosity is (big). 3. lime slurry hardening in the air, is composed of (crystal) and (carbide) process at the same time to complete, so it belongs to the lime (air hardening cementitious material). The molecular formula of four kinds of mineral composition of Portland cement clinker is 4. (C3A), (C2S), (C3S), (C4AF). Reasonable sand rate refers to the 5. concrete (water) and (cement) under certain conditions, can make concrete for maximum mobility, and can obtain good cohesiveness and water retention rate of sa
