Qualities of High-Strength Lightweight Concrete Used for Construction of Arctic Offshore Platform

Abstract

Concrete employed in oil exploration and production platforms for use in shallow offshore zones of the Arctic Ocean is required to be lightweight, yet high strength, and moreover possess adequate resistance to freezing and thawing. Generally speaking, lightweight concrete, using artificial lightweight aggregate, has lower freeze-thaw resistance and this presents a serious problem. The study reported here was carried out on the freeze-thaw durability, constructibility and other properties of high-strength lightweight concrete. This paper especially points out the governing factors influenzing freeze-thaw durability of this type of concrete and describes a method of manufacturing concrete possessing superior durability.

Experimental Study of High‐Strength Steel Fiber Lightweight Aggregate Concrete on Mechanical Properties and Toughness Index

“…Various short fibers are often used to reduce the brittleness of concrete [9]. Some researchers have proved that steel fibers impart good strengthening, toughening, and crack resistance to both NC and LAC materials, and such steel fiber reinforced concrete would have a direct effect on the deformation and seismic performance of the whole structure [10][11][12][13][14][15][16][17][18]. In practical application, with the increase of fiber content, the dispersion of steel fiber will become more and more difficult, increasing the bulk density of materials.…”
