This study proposes applying cold-bonded low calcium Class F fly ash (FFA) based artificial lightweight aggregate (ALWA) to partially replace natural fine aggregate in an ecological unfired brick with a low energy super-sulfated cement (SSC). To estimate the influence of ALWA on the brick properties, natural fine aggregate (FA) in the reference brick was substituted with ALWA at four different amounts of 25, 50, 75 and 100% by volume. |
