Data underlying the research of Sustainable Strength Optimization in PVA-Treated Palm Kernel Shell Laterized Concrete

This dataset supports a research study that investigates the sustainable strength optimization of concrete using polyvinyl alcohol (PVA)-treated palm kernel shell (PKS) as partial coarse aggregate and laterite as partial fine aggregate. The experimental research aims to assess the mechanical and physical properties—specifically compressive strength, tensile splitting strength, flexural strength, density, and workability—of the modified concrete mixes across different curing durations (7, 28, 60, and 90 days). Data were obtained through laboratory testing using standardized procedures, with mixes prepared at varying replacement levels (10% to 30%) for both PKS and laterite. The dataset compares treated and untreated samples and was generated to evaluate the performance enhancement provided by PVA treatment, contributing to the development of sustainable, lightweight, and structurally viable construction materials.

本数据集支撑一项研究，该研究针对以聚乙烯醇（Polyvinyl Alcohol, PVA）改性棕榈仁壳（Palm Kernel Shell, PKS）作为部分粗骨料、红土（Laterite）作为部分细骨料的混凝土开展可持续强度优化相关探究。本实验研究旨在评估不同养护龄期（7、28、60、90天）下改性混凝土配合比的力学与物理性能，具体包括抗压强度、劈裂抗拉强度、抗折强度、密度及工作性。数据集数据通过标准化流程的室内试验获取，两类掺料的替换率均设置为10%至30%的梯度变量，据此制备多组混凝土配合比。本数据集对比了改性与未改性试样，其构建目的为评估PVA改性带来的性能提升，助力可持续、轻量化且具备结构适用性的建筑材料研发。
