METHOD FOR INCREASING THE HEAT STORAGE CAPACITY OF BUILDING BLOCKS FROM A CALCIUM SILICATE MATERIAL AND A BLADE FROM A CALCIUM SILICATE MATERIAL

摘要

Method for increasing heat accumulator capacity of building materials from calcium silicate material, preferably aerated concrete stones, comprises providing phase change material (PCM) in encapsulated form to induce phase transitions; adding one or more raw materials and/or one or more intermediate products; and followed by binding. An independent claim is included for a building material of calcium silicate material, preferably aerated concrete, containing phase change material in encapsulated form, preferably in the form of microcapsule with a diameter of 1-40 mu m, preferably 2-20 mu m.
