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 research results show that when the fly ash content is under 30 %, the strength of rcc can be increased but the effect is a little ; and with the fly ash content increased the dry shrinkage of the rcc reduced straightly, and the abrasion resistance and freeze resistance increased obviously. ( 3 ) fly ash can increase durability of the rcc and under the experiment condition, the perfect mixing content is 30 %
試驗結果表明： （ 1 ）粉
煤灰摻量小於30 %時能提高碾壓混凝土強度但影響度不大； （ 2 ）隨著粉
