混凝土氣泡間距系數(shù)分析儀EL-QPJJ英文;
1) spacing factor
氣泡間距系數(shù)
1.The results show that there is no relationship between air content in fresh concrete and that in hardened concrete except concrete with SJ AEA,nor is there a necessary relationship between air content in fresh concrete and spacing factor of hardened concrete.
對(duì)比研究了摻6種引氣劑混凝土的含氣量、氣泡間距系數(shù)、孔徑分布及氣泡平均直徑等氣泡特征參數(shù)。
2.On the basis of Harbin-Dalian high-speed Passenger railway project, the main research work of this paper are: Railway Concrete Preparation technologies are studied,those are satisfied the cold area railroad concrete durability,and Frost resistance and spacing factor of concrete are studied, and critical spacing factor of different concrete are proposed.
本文以此為工程背景,主要研究滿足寒區(qū)鐵路耐久性要求的混凝土制備技術(shù);同時(shí),對(duì)混凝土抗凍性能及氣泡特征參數(shù)展開(kāi)研究,并提出不同類型混凝土的氣泡間距系數(shù)臨界值,為用氣泡間隔系數(shù)來(lái)評(píng)價(jià)混凝土的抗凍性提供理論支持。
