初凝 meaning in English
initial set; pre-hardening
◇初凝结 initial condensation; 初凝时间 [土] initial setting time
Examples
- Initial setting time
初凝时间 - The cement - soil mixing pile with concrete core is a new soil improvement method , it means that , a concrete core is plugged into cement - soil mixing pile . concrete core pile and the cement - soil mixing pile undertake together vertical load . it appropriately combines the advantages of the precast concrete pile with the cement - soil mixing pile
水泥土组合桩是在水泥土搅拌桩成桩之后，水泥土初凝之前，用压桩机械将预制混凝土芯桩压入水泥土体内，待水泥土凝固后，芯桩与水泥土共同工作，承受上部荷载的一种新桩型。 - In the study , a new kind inorganic anchoring material was developed , which consisted of special binder and aggregate , the former is made from clinker , blast furnace slag and compound admixture , and the later is superfine sand . effects of the factors such as clinker / slag , binder / sand , solution / binder and constituent of solution on the strength , set - time and contraction of the matrix made from the anchoring material were studied
上述分析研究得出以下结论：新型无机锚固材料具有早强、快硬、高强特点， 10h .抗压强度可达26 . 5mpa ， 365天强度可达144 . 0mpa ；初凝时间在40min . 3h .之间,且初终凝时间差在15分钟以内；在保湿条件下具有微膨胀性，膨胀率在0 . 5 %以内。 - Some conclusions are drawn : the compressive strength and flexural strength of cubic specimens of steel fibre reinforced concrete increase with the dosage of steel fibre ; without change of dosage of steel fibre , the elastic modulus of steel fibre reinforced concrete increases with the concrete age ; steel fibre reinforced concrete is of obvious function in cracking resistance , but there is no obvious function in avoidance of cracking ; for both common concrete and steel fibre reinforced concrete , the variation of the internal temperature is different from that of the external temperature before the initial set of concrete , and the internal strain of both two kinds of concrete is great , and , in general , the variation of strain of common concrete is much greater than that of the steel fibre reinforced concrete ; after the initial set of concrete , the variation of the internal temperature of both two kinds of concrete is similar to that of the external temperature , and the variation of the internal strain is relatively small
结果表明：钢纤维混凝土立方体的杭压强度、抗弯强度随着钢纤维掺量的增加而增大；在钢纤维掺量不变的情况下，钢纤维混凝土的抗压弹性模量会随着龄期的增加而提高；钢纤维对混凝土的阻裂作用很明显，而对混凝土起裂的限制作用不明显；在混凝土初凝之前，无论是普通混凝土还是钢纤维混凝土，内部温度的变化规律与外界温度的变化规律不同，并且此阶段混凝土内部应变的变幅很大，普通混凝土应变的变幅要比钢纤维混凝土应变的变幅大得多；在混凝土初凝之后，无论是普通混凝土还是钢纤维混凝土，内部温度的变化规律与外界温度的变化规律相同，并且此阶段混凝土内部应变的变幅很小。 - Abstract : the cause of underwater concrete reinforcing cage up - floating accident is improper operation , such as loose - placement of reinforcing cage , fast - drawing of conduct pipe , improper embedded depth of conduct pipe ; and the poor quality of concrete , for example , the slump , sand percentage , adhesiveness and initial setting time don " t meet requirement
文摘:水下混凝土浇注钢筋笼上浮事故的原因是操作不当，如钢筋笼固定不牢、提升导管过猛、导管埋深不当等，以及混凝土品质差，如坍落度、含砂率、粘聚性、初凝时间等不合要求。
