On the Factors That Determine the Bond Behaviour of GFRP Bars to Concrete: An Experimental Investigation

open access: yesBuildings, 2023
It is becoming accepted that glass-fibre-reinforced polymer (GFRP) is a credible and effective replacement for steel in reinforced concrete (RC) to meet structural requirements whilst addressing durability concerns posed by steel over the long term.

Experimental study of the material and bond properties of frost-damaged concrete [PDF]

open access: yes, 2011
In an extensive experimental investigation, several types of tests were conducted on a reference specimen and frost-damaged concrete. Two levels of internal frost damage were quantified by the relative dynamic modulus of elasticity and compressive ...

Evaluation of Pull-out Resistance of Geomembrane in Soil by Pull-out Test

open access: yesProceedings of geotextile symposium, 1994
The profile section of geomembrane-lined reservoirs was the liner coming up from the bottom of the pit, covering the side slopes, then running over the top a short distance. With regard to the stability of the running over, at the case of geomembrance runout only and no ancher trench at all, an exact knowledge of the interaction between geomembrane and
