The current Program Director at Major Roads Projects Victoria has been appointed to Executive Director on the North-South Corridor project in South Australia to oversee the highly complex final 10.5 km along with the $3 million tender just released to engage geotechnical experts to undertake investigations. This follows SMEC, WSP and Tunnelling Solutions mapping out test locations, depths, sampling and testing requirements earlier this year.

Researchers at the Indian Institute of Technology have published their investigations into whether self-compacting concrete may offer better bonding and strength due to heating. Also testing concrete with heat are researchers at the University of Johannesburg who have found that high-temperature heat treatment (HTHT) can reduce low resistance to extreme alkali attack in fly ash geopolymer concrete.

A state-wide Construction Panel in WA is set to minimise the cost of tendering, maximise the spread of work for small and medium-sized construction contractors, and expedite delivery of projects and create thousands of jobs.

However, Master Builders Australia that says the commercial construction sector is forecast to severely decline. Compared to its previous forecasts, MBA expects commercial building activity to be 15.7% lower in 2020/21 and slightly less the following year.

A team from Kanazawa University in Japan has tested the impact response of porosity-free concrete (PFC) in the International Journal of Civil Engineering. And a group of European and Norwegian researchers have published their findings of using urea from human waste as an accessible superplasticisers on the moon for lunar geopolymer mixtures. They found that the mixture for lunar concrete would be more malleable before hardening.
