BRANZ has been researching how to improve the insulation of concrete slab-on-ground floors and has found an alternative method which is practical and improves performance.
Heating costs could be cut if we do as Americans and Europeans do and add perimeter edge insulation to heated concrete floor slabs.
As suitable sand for concrete becomes harder to find, a research programme to review the alkali limits in concrete may also lead to better tests for industry.
Earthquake damaged precast concrete floors are the focus of detailed investigation to help understand the role system response plays on the performance of precast floors. The ultimate goal? To improve building safety and reduce damage.
A national research programme looking into precast concrete floor performance in earthquakes is likely to result in revised guidelines for seismic assessment and retrofit of buildings with precast floors.
New research shows that using natural supplementary cementitious materials (SCMs) with Portland cement can maintain the strength and durability of concrete while reducing carbon emissions. Changes to cement standards may be needed, however, before SCM use can grow.
Extensive research at the University of Auckland on carbon fibre-reinforced polymers (CFRP) helps understand how this material can be used for seismic strengthening, increasing existing buildings’ resilience.
