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。The expansion agents can only make up the shrinkage to some extent, and the compensation effects would be reduced when the retardener and fly - ash are used. the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness. under bad curing condition, the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property, while the nominal steels have very unobvious effects. to reduce the concrete shrinkage thus avoid the cracking, the former factors must all be taken into account in concrete proportion design to develop sound concrete
研究結果表明,水泥的品種和用量是影響混凝土收縮值的主要因素之一,當混凝土中水泥用量超過470kg / m ~ 3時,混凝土的收縮值超過400 10 ~ ( - 6 ) ,在約束狀態下存在高開裂風險;採用細砂使混凝土單位用水量顯著提高,收縮值也大幅增加;優質粉煤灰總體上能抑制混凝土的收縮,以超量方式摻入其抑制作用更加明顯,但粉煤灰混凝土早期的粘聚性較差,應注意養護,以免失水產生龜裂;早強減水劑和緩凝減水劑都會使混凝土收縮值增加;膨脹劑只能補償混凝土部分收縮,同時受緩凝劑和粉煤灰的抑制,而且膨脹使混凝土的體積安定性增加了不確定因素,膨脹劑不是解決混凝土收縮裂縫的良方。The concrete with the a 28 days compressive strength of c60 can be produced by using suitably pulverulent coal - fired ash, the higher the quantity of pulverlent coal - fired ash mixed in concrete with 10 % - 20 % is, the higher the strength of concrete is. then, we carry out the studies on the technics properties that reflect the comprehensive properties of concrete. we find that the separating and excreting water of the concrete can be avoided efficiently when the pulverulent coal - fired ash and superplasticizer are used suitably, the higher the quantity ration of coal - fired ash and super plasticizer are, the higher the caving degree of the concrete is
在上述研究基礎上,對摻細化粉煤灰后混凝土的強度變化規律進行了分析研究,在適當配合比及高效減水劑的作用下,摻一定數量的磨細粉煤灰,在28天齡期可以配製出抗壓強度高於c60的粉煤狄高強混凝土;當磨細粉煤灰以10 - - 20不同的摻量分別摻入粉煤灰中時,粉煤灰高強混凝土的強度隨摻量的增大,各齡期強度均逐漸降低;在摻入8硅灰+ 10粉煤灰可使高強混凝土的各齡期強度都有很大增加,當單摻8粉煤灰時,混凝土的後期強度增加較快;粉煤灰混凝土必須加入高效減水劑遼十l彬技術人學碩十學位論文後j 」能達到高強的目的。Fnj concrete high efficient rapid hardening water reducing agent
