【 摘 要 】

The thermal conductivity and porosity of marine concrete with different composition were measured by transient plane heat source method. The effects of aggregate volume fraction, sand ratio and water-cement ratio on thermal conductivity of marine concrete were investigated. Through the analysis of these factors and the comparison with other scholars, it is found that the thermal conductivity of marine concrete increases with the increase of aggregate volume fraction, decreases with the increase of sand ratio and water-cement ratio.
