Developments in lightweight, self-compacting and pumpable concrete

The article poses an interesting discussion on the advantages of course Lytag as an aggregate which is light on weight and low on cost. What i like, however, is that it reminds us that what may at first be obvious in the industry, can be turned on its head with further investigation. despite the individual figures of aggregates what several case studies have discovered, is that the combination of lytag course AND fine aggregate produces the most workable, flexible and time-effective concrete, and therefore that concrete is a subtle substance that can be vastly affected by small alterations in its composition.

Under Construction - TAC Headquarters, Gheringhap St geelong

Ive put in a few shots of this building because its sheer scale makes it easy to discern the distribution of loads throughout the structure. (note: This site visit was conducted along with another student, Ryan Mitchell, so some of the images may be shared)

Above: Heavy reinforcement bars have been employed in this structure due to the ceiling heights on each floor.
Above: Precast panels pinned and cleated into place

Above: Scaffold rails are an essential part of the construction process until windows and walls have been affixed.

Journal - The development of the residential steel framing industry in Australia

The development of the residential steel framing industry in Australia

Much the same as the journal article I posted on Concrete, "Structural concrete - 50 year perspective," this article covers the major steps forward that steel construction has made in Australia from the imported cast iron British kit homes of the mid 19th century right through to to the highly climate adapted innovative and competitive environment of today's steel industry. It provides a very concise diagram on standard domestic steel construction (pictured) as well as a break-down of the key areas of progress ranging from durability, quality of construction, flexibility of design, speed of construction and cost as well as environmental considerations, which have led to where the industry is today.

Journal - Structural concrete, a 50 year perspective

Structural Concrete - A 50 year perspective

This is one of the most straightforward articles i could find. I particularly like it because it outlines the development of concrete industry over the past 50 years by segmenting it into its various facets, ranging from the changes in government policy, changes in clients needs (more medium/high density work) changes in materials, operations and methods and building standards and codes. However, what makes this article so relevant to today is it shows not only the past but the future direction in the industry, most notably the growing emphasis on embodied energy and longevity of design.

GEELONG WATERFRONT CAROUSEL PAVILION
McGlashan-Everist Architects
(1999)

The pavilion was designed to house and showcase a restored 19th century steam carousel, and is an invaluable sculptural addition to the Geelong Waterfront.

I believe it is a local example of excellence in steel construction technology.
