Marine concrete structures are subject to the action of multiple environments during their service time. This leads increased deterioration in durability marine concretes under combined bending load and dry–wet cycles, salt freeze–thaw spray erosion. The main reason for damage above three is Cl- attack. free content (Cl-f) diffusion coefficient (Df) can explain concrete. paper considers actual ...

Despite the numerous advantages of using concrete with high strength capacity, the brittle behavior of high strength concrete (HSC) and higher production cost has limited its use in the construction industry. This research aims to develop a cost-effective approach for production of high strength self-compacting concrete with desirable performance in either compressive or tensile loading conditi...

This paper delineates the development of a prototype hybrid knowledge-based system for the optimum design of liquid retaining structures, OPTLIQ, by coupling the blackboard architecture, an expert system shell VISUAL RULE STUDIO and genetic algorithm (GA). Through custom-built interactive graphical user interfaces under a user-friendly environment, the user is directed throughout the design pro...

Concrete structures in marine environments are prone to deterioration and damage due chloride ion penetration, freezing thawing, chemical erosion. Ultra-high-performance concrete (UHPC) mixed with steel fibers has been proposed as a solution enhance the durability mechanical properties of environments. Although several studies have conducted this regard, they yet focus on addressing errors that...
