本文針對「輕質高強預應力混凝土平臺的研究」這一課題,從罐體結構型式的確定,混凝土基本材料及外加劑的選配,模型的設計製作,到模型結構在各種外荷載及溫度荷載作用下的受力性能試驗研究及罐體結構的有限元分析,展開了如下幾個方面的研究: 1Test results show that the steel fiber in concrete have more effectiveness on improving the splitting tensile strength and the flexural strength in the early age than after its hardening ; the flexural modulus of elasticity of sfrc are higher than the plain concrete at different ages while their compressive modulus of elasticity are almost the same. it ' s also shown that, similar to the plain concrete, the early - age loading decreases the strengths of sfrc, but, with the increase of the contents of the steel fiber things are getting better, especially for the splitting tensile strength and the flexural strength
試驗結果表明:與性能穩定之後相比,在混凝土中摻入鋼纖維對它的早期劈裂抗拉強度和抗折強度有尤為顯著的提高作用;對各齡期的受壓彈性模量影響不大,而對提高抗折彈性模量有一定的效果;與素混凝土試件相同,在早期(強度達到28天強度的85前)對鋼纖維混凝土試件施加荷載會對它的各種強度產生一定的不利影響,但是摻入鋼纖維可以減輕這種不利影響,尤其對劈裂抗拉強度和抗折強度作用突出,並且含纖率越高,效果越明顯。By static tests, studied the uf characteristics of the uf membranes, which have two kinds of intercept molecular eight, and made from pes, pek, spes and spk , in treating black liquid from basic straw pulp. the result showed : at the condition of static contacting, the pes and spes spk are polluted by composition of black liquid in a less degree, and the pek is in the heaviest edgree. the sulphonaled membranes with higher negative charge have better uf characteristics of black liquid. the uf membranes characteristics of 20 thousand intercept molecular weight are superior to 50 thousand intercept molecular weight
通過靜態試驗,研究了兩種截留分子量的聚醚碸、聚醚酮、磺化聚碸/聚醚碸、磺化聚碸/聚醚酮等超濾膜處理堿法草漿黑液的超濾特性,結果表明:靜態接觸條件下,聚醚碸及磺化類膜受黑液組份的污染程度較輕,聚醚酮膜的污染程度最重;荷負電性較高的磺化類膜具有較好的黑液超濾特性;截留分子量2萬的超濾膜特性要優於5萬的膜。Performance test for prefabricated reinforced components made of autoclaved aerated concrete or lightweight aggregate concrete with open structure under transverse load
