Polyurea has drawn the attention of construction activists and engineers as a modern
building material due to its unique structure, unique properties, and relatively easy …

Concrete-based pipelines or linings are widely used for water and sewer systems. However,
concrete pipes suffer from the problems of aging and deterioration due to complex loading …

Present work obviates the demand for petroleum products from the coating industry. The
current study highlights the potential of bio-based precursor ie, cardanol for synthesizing …

In this study, polyurethane/polyurea coatings were exposed to four different types of aging:

Buried culverts are important components of highway infrastructure. Most large culverts are
built decades ago from corrugated metal or reinforced concrete materials and now have …

The paper describes a part of studies under the research project “Polyurea coatings as a
possible structural reinforcement system”. The main goal of the experimental investigation is …

The internal replacement pipe (IRP) is a developing trenchless system utilised for restoring
buried steel and cast-iron legacy pipelines. It is crucial to ensure that this advanced system …

Polymeric spray lining is a trenchless pipe rehabilitation technique which is rapidly gaining
momentum, due to the increasing costs of open trenching or lift-and-relay replacement. An …

Legacy gas pipelines experience problems as they age. Pipe rehabilitation and replacement
using internal pipes or liners is a trenchless renewal approach to address these issue-prone …

The urban undersea road tunnels are featured with high frequent traffic congestions and a
strict environmental control standard. The internal environment in urban undersea road …
