The curing agent content plays an important role in the synthesis of polymer composites, as it determines the quality and durability of these materials. Cyanethyl-diethylenetriamine (CEDETA) was used as the curing agent for epoxy epikote 828. The effect of CEDETA content on the gel content and fracture toughness (KIC) of epoxy resin, as well as the effect of reinforcing fabric on the mechanical properties of composite materials was studied.

This paper reviews the durability of concrete containing pozzolans in marine environments, which mainly focuses on resistance to chloride ion penetration and sulfate attack. The results of previous literature showed that the main ions of seawater are almost similar but the salinity varies with location. The mechanism of chemical reaction between seawater and concrete was carefully reviewed and explained.

The aim of the work "Stochastic service life prediction of RC girders subjected to chloride induced corrosion – Shear limit state" presented in this thesis is service life prediction of corroded reinforced concrete girders, which forms an important part of durability design. The scope of this work is limited to shear limit state considering the chloride induced corrosion of reinforcement as the degradation mechanism. The review of literature shows that the service life estimation of reinforced concrete bridges exposed to marine environment is an active area of research.

The potential use of locally sourced ground granulated blast-furnace slag (GGBFS) and commercial sodium sulfate (Na2SO4) in the development of an eco-friendly sulfate-activated binder (SAB) was investigated in this study. The influence of Na2SO4 contents (1.5, 3.0, 4.5, 6.0, and 7.5% by mass of GGBFS) as a crucial sulfate activator on mechanical strength and durability performance of the SAB samples was evaluated through the tests of compressive strength, porosity, chloride ion penetration, and ultrasonic pulse velocity.
