The results of research on the workability of hbc concrete show that hbc concrete, when compared with opc concrete, has excellent compatibility with superplasticizer, in terms of better initial fluidity, less slump loss, definite saturation point and less dosage at saturation point. in addition, good mineral admixture such as i class fly ash can obviously improve the workability of hbc concrete. moreover, hbc concrete exhibits more excellent workability under the condition of low w / c ratio, which indicates hbc is more suitable for making super high strength concrete whose w / c ratio is very low
對高貝利特水泥高性能混凝土工作性能的研究結果表明,高貝利特水泥與高效減水劑具有良好的適應性,表現為初始流動度較大,經時損失較小,具有明顯的飽和點且飽和點摻量較小;此外,優質的礦物摻和料如一級粉煤灰能明顯改善hbc混凝土的工作性能;更為突出的是hbc混凝土在低水膠比的情況下表現出更為優異的工作性,這一特性預示著高貝利特水泥更適宜配製水膠比很低的超高強混凝土。First, it is compressible and cushiony ; second, it can be transported to a long distance with a little power loss ; the last, its flux and velocity of flow are quite high, so the reaction time of the operators can been considerably shortened. aiming to solve the problems of vibrating machinery such as short life - span, poor cushion and high energy consumption, the writer, on the basis of characteristic of pneumatic mentioned, contrives a set of valve controlled pneumatic vibrator, which has larger output vibrating force and longer life - span with simple structure. then, it is applied to drive a vibrating screen and the result is fairly well

儲蓄期限一般較短,而按揭貸款的還款期限較長,銀行長期資產與短期負債不匹配,就不能化解未來不確定性帶來的風險;二是資產的流動性和期限呈反方向變動,期限越長,流動性越低,住房抵押貸款本身的特性決定了其流動性較差,因此目前各銀行都嚴格限制貸款期限;三是風險大,由於按揭貸款是期限很長的債權資產,銀行面臨的利率風險就很大;另外,當客戶因某種原因失去償還能力或者認為違約產生的利益超過違約所產生的損失時,就會發生信用風險,而銀行以金融產品為主要業務,即使收回抵押物,但如何處置不良資產仍是諸多銀行頭痛的問題。Municipal slow - flow water bodice are destroyed due to influence from cites development and characteristics of small mobility and week self - purification ability
