structural lightweight aggregate meaning in English
结构用轻骨材
Examples
- We have been produced high fluid structural lightweight aggregate concrete which apparent density is 1800kg / m ~ 3 and 28d compressive strength is 50 ~ 60mpa by
对轴心抗压强度、抗折强度、弹性模量和抗渗性能的检测表明，所配混凝土具有良好的物理力学性能和耐久性。 - To obtain high fluid structural lightweight aggregate concrete with good uniformity , it is necessary to limit the max grain size of lightweight aggregate to 20mm , cement content to 500kg / m ~ 3 and slump of concrete mixture to 260mm
要获得均匀稳定的大流动性结构轻集料混凝土，陶粒的最大粒径不宜超过20mm ，水泥用量不宜超过500kg / m ~ 3 ，拌和物坍落度宜小于260mm 。 - In addition , vibration has great effects on uniformity of high fluid structural lightweight aggregate concrete . there is obvious separation of lightweight aggregate from mortar in mixture of high fluid structural lightweight aggregate concrete with slump of 220mm when vibrated for 10 minutes
此外，振动对大流动性轻集料混凝土的匀质性十分不利，对坍落度220mm左右的轻集料混凝土拌和物，振动时间超过10秒，就会出现明显的分层现象。 - This paper deals with high fluid concrete in which high strength ceramsite made from shale was used as coarse aggregate . effects of cement content , water - cement ratio , sand percentage , mineral admixture , grading and pretreatment of lightweight aggregate on compressive strength and workability of high fluid structural lightweight aggregate concrete have been studied . the rules of water absorption of high strength lightweight aggregate under different pressure and effects on uniformity of high fluid structural lightweight aggregate concrete have been studied too
