Characterization of Superplasticized Blended Cement Grout for the Application on Semi-Rigid Pavement

抄録

Semi-rigid pavement is an alternative solution to overcome the limitation caused from the commonly used pavements.It consists both the flexibility from the bituminous component and the rigidity from the cement constituent. Blended cement (BC) plays an important role in the replacement of OPC and this study will investigate the effect of Superplasticizer-X and water/binder ratio of cementitious grout using BC. A wide range of mix trials were formulated using BC and additive-H in order to achieve a pourable consistency of cementitious grout.The self compacting grout is required to impregnate into the porous asphalt skeleton under the influence of gravitational force and at the same time maintain a high compressive strength with the aid superplasticizer. The fresh and hardened cementitious grouts were analyzed for its workability and compressive strength.
