  • Non-burnt earth block with magnesium oxide for load bearing masonry wall

    Wataru Nakamura; Naoyuki Koshiishi

    In order to address global environmental problems, the use of earth material has many environmental advantages. This paper proposes the use of non-burnt earth block, stabilized with magnesium oxide (MgO), as the masonry unit for load bearing wall. This study puts its focus on making mechanism that can find the possible mix proportion of earth block that satisfy the required quality and manufacturing conditions. It was found that the hardening mechanism of MgO is due to the formation of magnesium hydroxide, and the water-MgO ratio influences the compressive strength. Furthermore, some properties of the earth block depend on the proportions of the fine particle, MgO and water. These relations of properties and mix proportions were also confirmed in the experiment that used other kinds of clay sampled from different areas., Architectural Institute of Japan, 01 Oct. 2017, Journal of Structural and Construction Engineering, 82 (740), 1527 - 1535, doi

  • The study of non-burnt earth blocks used for masonry load bearing wall in small scale detached house

    Wataru Nakamura; Naoyuki Koshiishi

    Earth materials have great possibility of saving the burden on global envrironmmaent. How erver, the utiliozation ways of earth matrerial are limited within traditional clay wall and earthenware products. This paper reported the results for the experiments that aimed to use the nonburnt earth blocks as the masonry units for the load-bearing exterior wall of small scaled etached house. Magnesium oxide was used as the additives to enhance the compressive strength and water resistance based on the expe rim ent, and then the influence of thee mix proportion and manu facturin g conditions a wsseurme ing outdaoteor and handmade were investigated., Architectural Institute of Japan, 01 Feb. 2015, AIJ Journal of Technology and Design, 21 (47), 17 - 22, doi
