- Abstract : by adding into concrete batch with greater proportion of active fine additive and pumping agent , reacted to the compound impact of the two substances , concrete workability , durability and strength could be improved . in addition , pumping - suitability of low strength concrete may be improved as well
文摘:将大掺量活性细掺料和泵送剂加入混凝土拌合物中，两者的复合作用下，可使混凝土的工作性、耐久性,强度得到改善，并提高低强混凝土的可泵性。 - The result of macro - quality experiments show : mineral admixtures markedly slow the hydrating velocity of cement slurry , decrease and delay the hydrating max - temperature , in which steel slag is more effective ; expansive agents compensate concrete shrinkage , enhance the concrete dense degree , strengthen the interfacial layer between fiber and cement matrix and improve the physical mechanics qualities of acic ; minimal admixtures markedly improve the concrete workability property , increase the concrete later intensity & density and the capability of anti - chemical attack and anti - permeability ; hybrid fiber reinforces the toughness of obviously acic by the means of anti - cracking effect of fiber with different sizes and different properties in the corresponding construction levels
实验结果显示：钢渣掺合料能显著减缓水泥浆体水化速率，降低砂浆的水化温升并延迟最高温升时间；补偿混凝土收缩，提高混凝土密实度，加强纤维与水泥石的界面粘结，增强混凝土力学性能，但不能明显改善混凝土韧性。混杂纤维通过纤维的不同尺度与不同性质在相应的结构层次上产生阻裂效应，增韧钢渣防渗抗裂混凝土；增加混凝土的破坏极限能，极大提高混凝土抗弯曲能力和韧性指数，改善混凝土脆性。 - 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
