Stability of Floating Body Using Moderate Lightweight Concrete Mixed with Crumb Rubber and Polymer

Abstract:

The purposes of this research is to study the stability of floating body using moderate lightweight concrete of which the gross weight was modified by crumb rubber and polymer. The moderate lightweight concrete was prepared by replacing 10%, 20% or 30% of sand in weight with crumb rubber of size No.6 or No.26 and mixing with the fluid polymer latex in 7.5% or 15% of the weight of cement. The test results shown that the concrete 626CR10-7.5, replaced sand with 5% No.6 rubber and 5% No. 26 rubber and mixed with 7.5% polymer, had better permeable resistant. Six pieces of models in the shape of open box were produced using the common concrete and concrete 626CR10-7.5. The stability of floating concrete body was tested and the metacentric height and the period of roll were calculated based on the test data. It is concluded that the moderate lightweight concrete behaved better stability and was appropriate material for floating concrete structures.
