Abstract:In order to study thermal conductivity of concrete produced by modern construction technology,influencing factors on thermal conductivity of normal strength concrete,high performance concrete,recycled concrete as well as reinforced concrete were quantitatively investigated by the stable plate thermal conductivity meter.Seven testing variables,including the aggregate volume content, water-cement ratio(m_w/m_c),types of aggregate,admixture content,temperature,moisture of specimen and reinforcement volume cont...
