...Abstract This work presents experimental results comparing the corrosion durability of two formulations of a novel, non-hydraulic, calcium silicate cement (CSC) concrete to that of one type of ordinary Portland cement (OPC) concrete. Cured CSC-based concrete has a lower pore water pH (9-11) than...

... the coating robustness and the influence of nano-particles to mitigate corrosion. Environmental pre-exposure to humidity didn’t appear to have a detrimental effect on the coating durability. Both coatings allow moisture intrusion inside the system and EIS can be used as an effective tool to estimate...

NPE-ZRP Coating Carbon Nano-particles Polarization Corrosion Durability INTRODUCTION NPE-ZRP and ZRP coatings were applied over A36 carbon steel coupons (76.2 mm x 127 mm x 3.2 mm) following the manufacturer requirements. Coatings...

... which is the main reason of short-lived repair. Ultra-high-performance concrete (UHPC) has been promoted as a durable construction material that can provide a barrier to corrosion due to its low permeability, ideally resulting in a durable repair solution with no need for other corrosion control systems...

...Abstract In offshore context, maintenance coatings do not aspire to “high durability” status. New construction protective coating processes, aspiring to such status, often fail to deliver it. The “high durability” aspiration, still, produced a divide between surface tolerant materials...

... that can make electrochemical reactions take place outside the TSA/coating crevice and (iv) sacrificial coatings. A number of coatings have been selected for testing with this in mind and tested in the ISO 20340 cyclic ageing test. TSA repair coating durability INTRODUCTION Background Thermally sprayed...

Based on this analysis E-CR-FRP provides higher design life (20 years for E-CR-FRP over 3 years for SS alloys in Hydrochloric Acid) and huge cost savings in corrosive environments over SS. Corrosion Durability E-CR...

... field testing of coupons may be used to develop a reasonable estimation of long term durability. However, this durability may come at a high price. Abstract Measuring the durability of glass fiber reinforcements via weight loss methods is confounded in many chemicals by re-deposition of leached...

...Estimating the remaining service life of corrosion-affected reinforced concrete (RC) structures is required by asset owners and practicing engineers for repair and maintenance planning. Corrosion durability of RC structures exposed to chloride-containing environments is measured by the length...

... back to the reservoir. However, the linings are susceptible to deterioration and have a finite life. Research was undertaken to improve the durability of cementitious linings and thereby increase the service life of lined pipes. Samples of mortar were exposed to simulated hypersaline geothermal brine...

... increased as the crack width-to-cover ratio increased for both types. Corrosion-based projection models indicated strongly enhanced performance for the 0.02-inch (~0.5 mm) cases compared to the 0.1-inch (~2.5 mm) cases.
