摘 要: 试验研究了聚氨酯泡沫废弃物掺入混凝土之后的力学性能,干缩性能以及密度与其之间的关系,结果表明:聚氨酯泡沫塑料废弃物可用于制备轻质混凝土,强度符合国家标准,堆积密度和混凝土的绝对密度之间具有准线性关系,干燥收缩符合轻质混凝土水含量演变规律。 This paper tests and studies the mechanical performance of polyurethane foam waste mixed with concrete and the relationship between dry shrinkage and density as well. Results show that polyurethane waste can be used in fabricating lightweight concrete, the strength meets the national criteria, there is quasi-linear relationship between piling density and absolute concrete density, dry shrinkage meets the evolution law of lightweight concrete moisture.
