Pilot with inspection pit made of self-compacting geopolymer concrete

The construction team consisting of the municipality of Huizen and Dura Vermeer is conducting a sewer reconstruction on Rokerijweg, Industrieweg, and Fabrieksweg. In four phases, the entire pavement and drainage system will be excavated, and a new sewer system will be installed.

Reduction of CO2 Emissions

Dura Vermeer aims to halve our CO2 emissions by 2030. A significant source of CO2 emissions in the construction sector is the production of concrete, with the use of Portland cement being responsible for approximately 6% of global CO2 emissions. In the Netherlands, this percentage is around 1.5% due to the use of Blast Furnace Slag cement. With a substantial CO2 reduction of over 35% compared to traditional concrete, self-compacting geopolymer concrete is introduced as a promising solution for mitigating CO2 emissions.

Geopolymer Inspection Pit

On the project in Huizen, the construction team collaborates with Martens Beton. Martens has independently developed a geopolymer concrete. As a concrete step towards reducing CO2 emissions in practice, Dura Vermeer recently installed the first inspection pit made of this type of concrete. With internal dimensions of 1000 x 1000 mm, this innovative inspection pit serves as a tangible example of the commitment to alternative materials. It represents a promising stride towards the use of more sustainable materials in the future.

Municipality of Huizen: "By implementing this pit, experience is gained with this new technique, which holds promise for widespread application in public spaces."

Geopolymer Concrete

Martens has independently developed a geopolymer concrete under the brand name "Zero." What makes this concrete mix unique is its self-compacting property. This pit represents one of the first applications of self-compacting geopolymer concrete in the Netherlands. One of the advantages of this type of concrete is its high level of resistance to acids and chemicals. In the coming months, Martens Beton will conduct pilot projects with this concrete on multiple construction sites.
