Environmentally friendly concrete walls hide the building from prying eyes.
The production of cement, used in concrete, is a major source of emissions CO2 in the world. Nendo has set an example for greener construction. Her Block-Wall House project is partially built with innovative concrete that absorbs carbon dioxide rather than emitting it. writing A new atlas.
The block wall house is located in Nagano Prefecture, Japan, along a country road. There is a lot of glass, so to provide privacy and hide the home from passing vehicles and pedestrians, Nendo installed a tilting screen. Therefore, owners will be able to see what is outside, and random passers-by cannot look inside.
The screen consists of 2000 blocks arranged in parallel rows. Five walls with a total length of 110 ma were built.
The concrete, called CO2-SUICOM, was developed by Kajima Corporation. During the production process, a special cement mixture is placed in a curing chamber and then pumped into the chamber CO2 for inclusion. Included CO2 then gets stuck inside the concrete and is not released. Its strength is not inferior to ordinary concrete.
Regular concrete hardens through a chemical reaction between cement and water. CO2-SUICOM is a new type of concrete that uses γ-C2S material instead of conventional cement. γ-C2S hardens by reacting with CO2 in the air, not in the water. With that CO2-SUICOM can include CO2 from the atmosphere during solidification, making it ideal for construction near emission sources CO2for example, power plants.
The production cost of CO2-SUICOM concrete is so far three times higher than the standard concrete used in Japan. But Kajima believes that the material will become more accessible in the near future.
Before that we showed nice little house – only 6 meters long. This tiny home is designed for four people.
