EXPERIMENTAL ANALYSIS OF ABRASION RESISTANCE IN PAVER BLOCKS WITH NANO-PARTICLE ADDITIVE

The abrasion resistance of paver blocks containing nano-particles for pavement is experimentallystudied. Both nano-TiO2 and nano-SiO2 are, respectively, employed to be as the additives. Forcomparison, the abrasion resistance of plain paver block and the paverblock containing polypropylene(PP) fibers is also experimentally studied in this work. The test results indicate that the abrasionresistance of concretes containing nano-particles andPP fibers is significantly improved. However,the indices of abrasion resistance of paver block containing nano-particles are much larger than thatof paver block containing PP fibers. The abrasion resistance of paver block containing nano-TiO2 isbetter than that containing the same amount of nano-SiO2. The enhanced extent of the abrasionresistanceof paver block decreases with increasing content of nano-particles. Finally, the relationshipbetween the indices of abrasion resistance and compressive strength of concrete, water absorptiontest will find out.
