摘要: Firstly, this paper will describe the fundamental study on water-soluble polymers and polymeric superplasticizers which are appropriate to non-dispersible underwater concrete. Through several laboratory tests carried out those additives, most suitable combination of a polymer superplasticizer for concrete was found out. Taking these results into account, an admixture called aklith 12 formulated. Secondly, outlines joiluc containing mentioned above be described. Furthermore details its typical retarding property is indispensable practical application massive explained. Thirdly, description given large-scale test that examine flowability qualities when it allowed flow over long distance. results, allowable maximum space interval between tremie pipes clarified so far as prescribed were assured.
