建筑物混凝土垃圾试样的物理力学性能分析

Analysis of Physical and Mechanical Properties of Construction Concrete Waste Samples

对兰州市雁滩某高层住宅地下室底板混凝土的钻芯取样进行抗压强度测定.通过试样破坏及曲线分析,判断其破坏形态,根据实验强度推定混凝土结构的实际抗压强度值;并对该底板部分混凝土破碎、筛分,做相关物理性能试验.为后期再生混凝土的研究提供参数依据.

By core boring sampling the basement foundation slab concrete of a Yantan high-rise residential build- ing in Lanzhou City, its compressive strength is determined, and its failure mode is judged through sample de- struction and curve analysis. The actual compressive strength value of concrete structure is estimated according to laboratory strength. After crushing, sieving a small portion of the basement foundation slab concrete, related physical performance test is carried out in order to provide parameters for of recycled concrete study of the later period.
