Dataset on the assessment of pervious concrete containing palm oil kernel shell and seashell in heavy metal removal from stormwater.

The dataset currently available comprises the rate of heavy metal removal by pervious concrete incorporation seashell and palm oil kernel shells from stormwater. Stormwater runoff was collected from commercial area at Taman University, Skudai, Johor, Malaysia. The stormwater sample underwent filtration and was preserved in high-density polyethylene (HDPE) bottles at a temperature of 4°C for use as the incoming water. The outgoing water, referred to as effluent, was obtained from tests performed on pervious concrete samples after a curing period of 28 days. The previous concrete mixes were created with a water-to-binder ratio (w/b ratio) of 32% and a sand ratio of 10%, respectively, three palm oil kernel shell and seashell contents, namely, 0, 25 and 50% as coarse aggregate replacement, two median particle sizes of both palm oil kernel shell and seashell, namely (6.3-9.5 mm) and (4.75-6.3 mm. Heavy metal analyses were measured on influent and effluent by a Perkin Elmer ELAN 6100 Series Inductive Coupled Plasma–Mass Spectrometer (ICP-MS). The available datasets are raw and analyzed data.

现有公开数据集涵盖了掺入贝壳与棕榈仁壳的透水混凝土（pervious concrete）对雨水中重金属的去除率。雨水径流采集自马来西亚柔佛州士古来（Skudai）大学城（Taman University）商业区。雨水样本经过滤处理后，装入高密度聚乙烯（HDPE）瓶中，于4℃环境下保存，作为试验进水使用。经28天养护的透水混凝土试样试验所得出水即为出水（effluent）。本次透水混凝土配合比设计参数如下：水胶比（w/b ratio）为32%，砂率为10%；以棕榈仁壳与贝壳作为粗骨料替代料，设置3种掺量，分别为0%、25%与50%；棕榈仁壳与贝壳的粒径中值均设置2组，即(6.3~9.5 mm)与(4.75~6.3 mm)。采用珀金埃尔默ELAN 6100系列电感耦合等离子体质谱仪（ICP-MS）对进水与出水样本进行重金属含量分析。本公开数据集包含原始数据与分析后数据。
