Failure probability of coarse aggregates ( pfca ) could be a sample index durability evaluation of concrete in compressive strength test , where pfca was the ratio of number of total particles to which of the broken ones of coarse aggregates in the failed faces of a concrete specimen 混凝土抗壓試驗中,粗集料破碎率p _ ( fca )可以作為混凝土耐久性的一個簡要評價指標(biāo),其定義為試件斷裂面上破碎的粗集料顆粒數(shù)與暴露的粗集料顆??倲?shù)之比。
Some results are obtained in this section . 1 ) the volatility of china ' s stock markets is higher than that of developed stock markets . 2 ) the volatility of shenzhen sample index returns becomes more and more higher , this suggests that its role as a market radiator is more and more weaker 我們在這一部分的實證研究表明: ( 1 )作為新興市場的中國股市,其市場波動的程度與頻率明顯高于發(fā)達市場; ( 2 )深證成份股指數(shù)在股市迅速擴容的過程中,其市場指示器的作用越來越弱。
With mortar being separating matrix , from aspects of theories and test - methods of workability - design , separation mechanism of water - reducer for cement paste , relation between properties of interfacial zone and concrete durability etc , this work focused on sample index for durability evaluation , saturation dosage of water - reducer , test for rheological properties of mortar and test on concrete workability etc , achieved following main conclusions . 1 本研究以砂漿為分散體系,對混凝土的工作性設(shè)計從理論到測試方法、從減水劑對水泥漿體的分散機理、從混凝土界面性能與耐久性的關(guān)系等不同角度,對砂漿流變性能的測試方法和混凝土工作性的測試、減水劑飽和摻量、耐久性簡要評價指標(biāo)等方面進行了研究,得到以下主要結(jié)論。
