Here the hsc of sompa is achieved through adding super - effective water reducer , fined slag and silicon fume , and decreasing the water / cement ratio . by varying the area ( spacing ) of tension bars , compressive bars , vertical links and distribution steel and embedding steel fiber and polypropylene fiber we try to improve the behaviors of reinforced high performance concrete one - way spanning slabs in bending , so that its ductility be greater than 5 . with the same arrangement of steel the width of bending member is varied to observe the effect of the width / depth ratio on the ultimate compressive strain of concrete 通過變化受拉筋含筋率和受壓筋、箍筋(鉤筋、分布筋)含量,或摻加纖維使之成為鋼纖維高強混凝土( sfrhsc )和聚丙烯纖維高強混凝土( pfrhsc ) ,對高強混凝土雙筋截面梁、板的受彎性能進行了試驗研究,試圖改善高強混凝土受彎構件的延性,使其延性比大于5 ;并在相同配筋情況下,通過變化截面寬度,研究了高強混凝土受彎構件的寬高比對壓區混凝土極限應變的影響;并對試驗構件的裂縫發展情況進行了觀測。

The green body of high quality could be obtained at injection molding temperature from 160c to 180 c , injection molding pressure from loompa to 120mpa , keeping pressure from 40mpa to sompa , mold - temperature 32c , cooled from 2 min to 4 min 注射溫度為160 180 ,注射壓力為100 120mpa 、保壓壓力為40 50mpa 、模具溫度為32 、冷卻時間為2 4min注射成型后,注射坯的質量較好。
