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。
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。
