摘要： The present application belongs to the technical field of civil and architectural engineering materials, and in particular relates to an environmental and low-carbon foamed lightweight soil prepared by using CO2 and MgO as raw materials. Raw material compositions of the carbon sequestration foamed lightweight soil include, in parts by weight, 10 to 200 parts of MgO, 10 to 100 parts of a filler, 2 to 45 parts of a CO2 bubble cluster and 20 to 400 parts of water. The present application is made in view of the problems of large carbon emission and serious energy consumption caused by a cement solidification agent used in traditional foamed lightweight soil.

摘要： A method for producing calcined clay having desired colour characteristics. The method includes: a step of calcining a clay in a calcination furnace, the calcination step being carried out under stoichiometric or oxidising conditions, and a step of reducing iron (III) oxides present in the calcined clay in a reduction system separate from the calcination furnace, this reduction step being carried out by injecting a reduction gas, containing hydrogen atoms and placed in direct contact with the calcined clay.
