How to reduce cement CO2 emissions
12 November 2019
CO2 emissions created from cement production can be minimized in two main ways:
- Changing how concrete is made,
- Using less concrete.
Following the continuous increase of building stock, scientists are working on new cement formulas that will significantly lower or eliminate the CO2 emissions. Some expect to create the emission-free cement made without the use of fossil fuels and use the electricity from renewable resources. There is scientific research going on in many laboratories – MIT research, Portland Limestone cement, or Cenin cement, to name a few.
The other approach aims to massively reduce concrete use. This means inventing products that, embedded in construction, reduce the concrete volume used on the scale of the whole building. Supporting this option, especially in large-scale projects and complexes, our foundations and slabs products help decrease CO2 emission and save up to 20 % of concrete. Reduction in concrete also reduces building time and machinery use, which also reduce CO2 emissions.
Large projects significantly decrease concrete and pollution. Our products were used in following large-scale projects and complexes, saving the concrete and improving sustainability and resilience.
Ventilated foundations of new university campus were created with Modulo and Multimodulo. The surface of 19,000 m2 were built with crawl space beneath, to provide space for infrastructure pipes and appliances.
Mixed-use complex Vadikoru in Istanbul hosts various facilities. Lightened slabs were chosen as solution to provide adaptable and transformable interior space. Around 80,000 m2 were built with New Nautilus Evo.
Large scientific complex near Paris consists of several buildings recognizable by their round plan. To plan the interior space divisions, it was necessary to create the structure freed from columns and beams. Airplast slabs formwork was used to create monodirectional slabs on surface of 50,000 m2, thus decreasing the weight of the structure.
