Characterizing tribological behavior of fresh concrete against formwork surfaces
نویسندگان
چکیده
Concrete walls are constructed by pouring fresh concrete in-between formworks. The lifespan of these formworks is limited due to the abrasive nature concrete. present work investigates wear metallic and polymeric-coated plates in contact with Two formulations were studied: standard self-consolidating A plane-plane tribometer was used control friction against plates. This device reproduces implementation formwork. Results revealed a Coulomb law within range tested normal pressures. testing induced changes surface topography evolution associated two underlying mechanisms: granulate-formwork solid-solid capillary-dominated friction.

Influence of Controlled Permeability Formwork on the Permeability of Concrete
Corrosion of steel reinforcement related to the intrusion of chloride ion is still the main threats to the durability of concrete structure, especially in marine environment. For the purpose of delaying the Cl− concentration at the surface of steel reinforcement reaching the critical value leading to initial corrosion, the permeability of concrete is usually improved by optimizing the concrete ...

It is characterized b~ a dependence on contact pressure and sliding velocity. The identification of the required pa...
متن کاملPhase Complexity Surfaces: Characterizing Time-Varying Program Behavior
It is well known that a program execution exhibits time-varying behavior, i.e., a program typically goes through a number of phases during its execution with each phase exhibiting relatively homogeneous behavior within a phase and distinct behavior across phases. In fact, several recent research studies have been exploiting this time-varying behavior for various purposes. This paper proposes ph...
متن کاملAn Experimental Study on Effect of Waste Tire Rubber on the Fresh and Hardened Behavior of Self-compacting Concrete
The development of environmentally accepted methods of used tire disposal is one of the greatest challenges that waste management experts face today. Use of waste rubber particles as aggregate in self-compacting concrete is a suitable solution for the environmental hazards of waste tires being produced on a large scale. The aim of this work is to investigate the influence of the size of waste r...
متن کاملTribological behavior of PEEK components with compositionally graded PEEK/PTFE surfaces
PEEK is a high strength engineering thermoplastic that suffers from a high friction coefficient and a friction induced wear mode. Past studies with 0 m PEEK and PTFE powders resulted in composite solid lubricant that (at the optimal composition) had a wear rate of k= 2× 10−9 mm3/Nm ith a friction coefficient of μ= 0.12. A compositional grading of PEEK and PTFE is implemented in this study to cr...
