WP2 – Cost & environmental benefit analysis

Calculations of cost / benefit and greenhouse gas emissions related to the various tested combinations have also been performed. In short, it was concluded that:

100 kg of 50 % CEM / 50 % Stabila B100 gave highest cost and CO2 emissions per m3 stabilized soil, appr. 235 NOK and 82,5 kg CO2 per m3 stabilized soil
30 kg of 50 % CEM / 50 % Stabila B60 gave lowest cost and CO2 emissions per m3 stabilized soil, appr. 142 NOK and 21,5 kg CO2 per m3 stabilized soil
Appr. 40-70 % of total construction costs and 0,7-2,2 % of CO2 emissions originates from installation works (excluding mobilisation/demobilisation of equipment). It should be noted that the construction cost will vary depending on site conditions, contractor, availability etc.
