Added quantity of concrete的用法和样例：
- Results indicate that the metallurgical properties of sinter decreased gradually with add quantity of Indian iron ore increasing.
- Ductility ratio can be predicted also by prescribing the quantity of longitudinal steel proportionally to lateral steel and the strength of concrete.
- In addition,water quantity of concrete is bigger,plastic shrinkage of concrete is bigger when water to cement ratio is invariable.
- The results show that factors affecting the pore diameter of porous materials are the sintering temperature and time, the added quantity of pore former and the granularity of glass powder etc.
