Aerated concrete paste recipe is for a density of 500 kg/m 3 .Water is supplied both from city water supply network and water wells located atthe same site. Information about materials, relevant to inventory analysis issummarised in Table 2 and in Figure 2. Raw material consumption figures in thetable are determined by calculations based on annual production of the factory andAAC recipe obtained from product literature [8].3.3. Manufacturing of Masonry Wall ProductsManufacturing phase of a building product covers intermediate manufacture,product fabrication and/or assembly, packaging, and distribution activities.Additionally, it can cover raw material conversions not accounted for in thematerial acquisition stage [2].646
