On-site research for Assignment (concrete column construction)

Reinforced concete column construction:
Photo 1 shows bent reo coming up through column. Will go into beam.
Photo 2 shows reinforcement protruding through slab. Reo for next level of columns is spliced onto these.

Concrete finishes 5

Sometimes ugly concrete tilt up panel buildings have their use. This one along the railway line in Collingwood provides a canvas for a bit of urban art - grafiti art and milk crate art. (The Age 21.5.07)

Article Review

Technicalities - 'Toyo Ito builds a concrete cloud' Russell Fortmeyer (Architectural Record 03.07)

This article describes a recent building by Toyo Ito - a crematorium in Japan. The building appears like a cloud floating above the ground but is actually an undulating concrete roof, anchored to the ground by colums that hold the structure up and hide a roof drainage system.

Fortmeyer describes how the roof was poured in five stages. Grinding machines were used between each pour to smooth the joint lines and provide a smooth surface. Concrete was poured onto a complex formwork arrangementof steel built on top of timber. A hard mix was used to prevent the concrete sliding down the slopes of the roof during pouring.

In situ concrete panels

Concrete wall panels were formed on site. Photo shows panels poured on top of each other. Reinforcement shown. Tench chairs can be seen.
