Durability of Fiber Reinforced Concrete of Marine Structures

The usefulness of fiber reinforced concrete (FRC) in various civil engineering applications is indisputable. Fiber reinforced concrete has so far been successfully used in slabs on grade, shotcrete, architectural panels, precast products, offshore structures, structures in seismic regions, thin and thick repairs, crash barriers, footings, hydraulic structures and many other applications. This p...

Marine Durability Characteristics of Rice Husk Ash-Modified Reinforced Concrete

This paper addresses the potential use of Rice Husk Ash (RHA) as a cementitious material in concrete mixes. RHA is produced from the burning of rice husk which is a byproduct of rice milling. The ash content is about 18-22% by weight of the rice husks. Research has shown that concrete made with RHA as a partial cement substitute to levels of 10% to 20% by weight of cement has superior performan...

Steel versus Steel-reinforced Concrete Bridges: Environmental Assessment

Bridge material selection has traditionally been b~ed on e.ngineering and economi~ criteria. With the increasing interest of the public, industry, and government m sustainable:: development, en~lronmental. assessment in construction is becoming more important. However, we need metrtcs and data on deSign alternatives for effective decision making. In this paper, we present results of a life cycl...
