2018-12-12ensp0183enspresistance. There is a difference in the abrasive resistance depending on test method. Keywords concrete, recycled granulated rubber, polypropylene fibers, steel fibers, wear grinding resistance, hydro-abrasive resistance. 1. INTRODUCTION Abrasion of concrete occurs due to scraping, rubbing, skidding or sliding of objects on its sur-face.Read More
As a complement, the scratch test allows to verify the resistance of a concrete floor to abrasion. Improve hardness on concrete floors. In areas of industrial activity, it is essential that the concrete floor is maintained in good condition despite the traffic of heavy machinery.Read More
2017-7-19ensp0183enspConcrete abrasion resistance is markedly influenced by a number of factors including concrete strength, aggregate properties, surface finishing, and type of hardeners or top pings. A large number of previous studies 1 -6 have indicated that concrete abrasion resistance is primarily dependent upon compressive strength of the concrete.Read More
Results of a wide-ranging investigation of the abrasion resistance of concrete are reported and the influence of watercement ratio, curing, workability, maximum aggregate size and the constituent materials is discussed.Read More
