Abstract This study aimed to determine the abrasion resistance of ultra-high-performance concretes (UHPCs) for railway sleepers. Test samples were made with different cementitious material combinations and varying steel fiber contents shapes, using conventional fine aggregate. A total 25 UHPCs two high-strength (HSCs) selected evaluate their depth wear bulk properties. The results coefficient v...

Incorporating Graphene Oxide (GO) in concrete composite has been a good alternative to Pristine due its hydrophilic nature and ability readily disperse water the consequent cementitious mix. The addition of GO mix found enhance mechanical properties. This paper aims assess abrasion resistance incorporated for application road pavement design. Experiments strength terms compression, workability ...

The main objective of this study is to evaluate the workability of fresh portland cement concrete while it is still in the mixing truck by determining fundamental rheological parameters (plastic viscosity and yield stress). Nine concrete mixtures with different values of yield stress and plastic viscosity were tested in a concrete truck. The measurements made with the truck were based on the ty...

Near-surface mounted (NSM) bars have been used for flexural strengthening of reinforced concrete members. The data available on this type of reinforcement technique are limited and typically, the bars or strips are embedded using an epoxy. Long term durability, abrasion resistance, and compatibility of the repair are important issues with this type of repair. One untested option for embedding t...

In the actual working conditions, ship lock concrete is affected by friction of ship’s hull and erosion wear traveling wave during flood period damaged CO2 in air waterfall period. To study performance degradation law under this condition, underwater method was used to approximate physical rising water period, accelerated carbonization simulate falling The duration abrasion are determined accor...
