Lightweight Aggregate Concrete in Norwegian Bridges - ESCSI

Lightweight Aggregate Concrete In Bridges To help bridge designers in their efforts to create optimum structures, the Norwegian concrete industry, in the mid 1980s, started to combine the technology of HSC/HPC with that of lightweight aggregate concrete (LWAC). The first pilot project, constructed in 1987, was a 49-ft (15-m) long pedestrian bridge built with LC-60-a lightweight con-crete with ...

ESCSI - Lightweight Aggregate - ESCSI

Brief History of ESCS and ESCSI. For over a century, ESCS has been used successfully in more than 50 different types of applications. The most notable among these are lightweight concrete masonry units, high-rise buildings, concrete bridge decks, high performance marine platforms, asphalt bituminous surface treatments, lightweight chip seal, soil conditioner and lightweight geotechnical fills.

Lightweight Aggregate Concrete in Norwegian Bridges

Lightweight Aggregate Concrete in Norwegian Bridges. This paper describes how one of the main characteristics of Norway is its long coastline. During the last century, a vast number of marine concrete structures have been built in order to facilitate communications and transportation. Since the 1970s, the discovery of large oil and gas fields off the Norwegian coast created the need for a ...

Exploring The Synthetic Aggregates Alternative Agg-Net

Bridges and concrete: In bridges and other structures, lightweight aggregates result in lightweight concrete, with some very big benefits. Weight reduction optimizes land use by affording a smaller footprint, and it uses less building materials. ‘The reduction in foundation loads may result in smaller footings, fewer piles, smaller pile caps and less reinforcing,’ says ESCSI. ‘Reduced ...

01/02/1995  An experimental study was carried out to measure the elastic modulus of lightweight concrete in function of the amount of lightweight aggregate. The elastic modulus of lightweight aggregate was obtained using composite theory models applied to the experimental data. Based on the Mori-Tanaka model, the elastic modulus of three different types of lightweight aggregates ranged

01/05/2019  Lightweight aggregate concrete is usually defined as a concrete having an air-dry density of below 1850 kg/m3 as opposed to a normal concrete having a density of about 2300 kg/m3 but a finite limit is undesirable. (Fahrizal Zulkarnain, ICBEDC. 2008)The lightweight concrete has its obvious advantages of high strength/weight ratio, good tensile strength, low coefficient of thermal
