The overall utilization of debris reaches 60 and production cost lowers with excellent social and economic benefits 其凝结时间、早强性能及后期强度均达国标425水泥的要求，废渣总利用率达60 ，生产成本降低，具有良好的社会经济效益。
The study shows that the flow ability has been greatly improved and its loss has been reduced , while the time of paste hardening has been delayed by adding the high - ti bfs powder 试验同时指出，高钛矿渣的掺入，明显提高了胶砂流动性，减少了流动度的经时损失，延缓了水泥凝结时间。
4 when keeping the cement quantity and water ratio changeless , it will increase the slump constant for at least 10cm to mix into fnj l , and the concrete strength after hardening is equal to the reference concrete 2用于夏秋季节施工和大面积滑模施工。调节掺量，可有效地控制砼的凝结时间，掺量可调范围大，塌落度损失小。
It can adjust the retardation time and water reducing ratio properly according to the customer s demand , and it is applied to various waterproofing concrete , especially the large application of waterproofing concrete in winter 混凝土凝结时间稍有延长可减少干燥天气时新浇混凝土的干缩裂缝，掺量必须严格控制和精确计量。
The effects of five common set - retarders on setting time of cement paste and concrete and strength of concrete are studied . to cement paste , amount of set - retarders added in cement has a critical value 论文分别研究了木钙、糖钙、酒石酸、焦磷酸钠和蔗糖共五种常用缓凝剂对水泥净浆凝结时间、混凝土凝结时间及强度的影响。
The result shows that blended cement mixed with activatory coal gangue powder has high compressive strength , however , with the increase of the admixture of coal gangue powder , flowability of blended cement paste become worse , and the setting time is not obviously affected 结果表明，掺入经活化处理的煤矸石粉配制的混合水泥具有较好的强度性能；随掺量增加，水泥浆体的流变性能变差，但对凝结时间并无明显影响。
On the base of experiment & study of tile influence of different gypsum on performance of portland - sulphoalminate composite cement system as set time , water requirement of normal consistence , strength , ect , the influence mechanism was discussed 摘要在试验研究不同石膏品种对硅酸盐硫铝酸盐复合体系水泥凝结时间、标准稠度需水量、强度等性能影响的基础上，探讨了石膏品种对硅酸盐硫铝酸盐复合体系水泥性能的影响机理。
For other decoration application , the dosage of mortar essence shall be 0 . 1 and construction shall be executed pursuant to general criterion requirements ; in plastering mortar , the dosage of mortar essence shall not be increased at will otherwise excessively long coagulation time is required , leading to delay of schedule 其它装修水泥砂浆晶掺量为0 . 1 ，按通常规范要求施工，抹灰砂浆不能随意增加掺量，否则会造成凝结时间太长，而影响施工进度。
( 4 ) the neat cement paste fluidity of copolymer would augment and the cohesiveness of cement would increase along with augmentation of pea dosage , but if the dosage was too big , the dosage of aa would be reduced , so it would reduce the carboxylic content of copolymer , and performance of water reduce would weaken , the dosage of pea23 can not more than 25 % . ( 5 ) the effect of water reduce would increase if the copolymer time increase 而与x40 ;比较，减水率、凝结时间、保坍性、抗压强度比等综合性能还有一定的差距，有待进一步的改进和研究。从合成pc23一6的工业性分析: pea23的酷化和pc23一6的共聚的放大试验看，其混凝土试验结果较为理想，且其合成工艺流程较为简单，具备高分子的合成条件:而从经济性分析， 30 % pc23一6水溶液的原料成本低于fdn ，其性能具有较大的优势，具有广阔的工业化的前景。
