【摘要】 在再生混凝土中掺入玻化微珠,研究其热工性能和基本力学性能发展的规律性,找出最优配合比,在玻化微珠再生混凝土的基础上,掺入引气剂进一步提高再生混凝土的保温隔热性能。研究结果表明,引气剂、玻化微珠改善了再生混凝土的保温隔热性能,当玻化微珠的掺量为120%,引气剂掺量为0.02%时,引气玻化微珠再生混凝土的导热系数仅为0.5685W/(m.K)。更多还原

【Abstract】 Recycled concrete is blended with glazed hollow bead,to study the development regularity of the thermal-insulation and the basic mechanical properties of recycled concrete.Find out the optimum mix proportion,and add air-entraining agent to improve the thermal-insulation of recycled concrete.The results show that air-entraining agent and glazed hollow bead improve the thermal-insulation of recycled concrete.When the dosage of air-entraining agent is 0.02% and the dosage of glazed hollow bead is 120%,the thermal conductivity of recycled concrete is only 0.5685W/(m·K).更多还原
