Technology Innovation

01 We’ve Green

: Creating an eco-friendly living space by
reducing greenhouse gas and using eco-energy

We’ve Green is an eco-friendly housing space that integrates and optimizes feasible eco-energy and technology for convenience of life. We apply ‘We've Green’ to reduce greenhouse gases and live a sustainable life where humans and nature coexist.

02 Utilization of Polysilicon Sludge

: Developing low-carbon concrete by using
wastes

In order to solve environmental energy problems, we have conducted a lot of research in the field of renewable energy, one of which is using sludge generated when producing polysilicon sludge (also called polysilicon sludge), which is the raw material for solar cells, to develop low-carbon/crude steel type concrete with significantly improved early strength compared to existing cement alternative materials.

• Application case :  Low-carbon / High early strength concrete manufacturing technology, composite panel for cement-free drywall
• Intellectual Property Rights :  Patent No. 10-2015-0098385

03 Functional Blast Furnace Slag Cement

: Applying functional cement which enables
early-strength development in low-temperature
environment

This technology uses organic and inorganic composite functional additives for blast furnace slag cement and the same to make blast furnace slag cement concrete. Doosan E&C's unique technology enables early strength development in a low-temperature environment where liquidity can be maintained. In addition, this blast furnace slag cement concrete technology, by controlling cement bleeding, reduces the initial drying shrinkage effect and develops medium to long term strength.

• Intellectual Property Rights :  Patent No. 10-2021-0080355
• Application case :  Administration Town Central Doosan We’ve, Doosan We’ve The Zenith Harbour City, Doosan We’ve The Zenith Central Saha

04 SEM-utilized Pile Filler

: Developing SEM ash admixture filler of
high-performance level and reducing the
construction cost

This technology uses the by-product (referred to as SEM ash) generated from thermal power plants with circulating fluidized bed combustion method as construction material; it is the raw pile filler used for the purpose of integrating PHC pile with the natural ground. We have developed an SEM ash admixture filler that satisfies the performance level of PHC pile filler and applies it to architecture construction and piling.
