DOUBLE LAYER RUBBERISED CONCRETE PAVING BLOCK

RUBBER TECHOLOGY

The objective of this research is to investigate the potential using of crumb rubber for the production of double layer rubberized concrete paving block and to investigate the rubber based cement composite morphological behavior. The Double Layer Rubberized Concrete Paving Block (DLRCPB) manufacturing process which is different from Concrete Paving Block (CPB). Two types of mixing required for base layer and facing layer. The Based layer which is totally rubberized layer and the facing layer which is concrete layer. The mechanisms of thermal degradation of PU forms is often describe as being as very complex. The thermal degradation of polyurethane occurs in main two stages. The isocyanates to polyol ratio affect the freezing properties between crumb rubbers to concrete composite.
