It possesses excellent performances such as light-weight, high-intensity, fire-resistance, sound-insulation, heat-insulation and no-pollution. Composed with concrete materials, a new type of bearing and energy-efficient block can be gained, which is kind of excellent wall materials and has a wide application prospect.展开更多

The simplified mathematical model was put forward to simulate the procedure of moisture evaporating for the densely porous tile. The results show that the capability of passive cooling of the porous tile is more than 5 ℃ with moisture content of 30% in Yangtze river region. Through the comparison between the measuring and simulating data,it can be proved that the simplified math model can be fully used to the engineering application,which provides a reference to explore the thermal performance of other porous material.展开更多
