摘要

遵守 ASTM C109/C109M-20 标准可确保水泥砂浆试样的质量。然而，要达到 ASTM C778-21 标准所要求的砂级配却很困难。本文介绍了一种在不影响 ASTM 质量标准的前提下调整砂子级配的快速方法。所建议的方法包括分析六种不同级配的硅砂样本、预筛砂、使用 Excel 求解器优化混合物配比、通过精确计算自动调整级配，以及验证级配以确保符合 ASTM 标准。调整后，对使用改良砂的砂浆进行了抗压强度测试，并将结果与标准级配砂的结果进行了比较。根据统计分析，新方法取得了可靠的结果，抗压强度与标准砂相似。这项创新提供了一种更有效的替代方法，为简化土木工程的实践铺平了道路。

Rapid, graded sand preparation method using grain size distribution results for cement mortar testing

Adhering to ASTM C109/C109M-20 standards ensures quality in cement mortar specimens. However, achieving the required sand gradation per ASTM C778-21 can be challenging. This paper presents a faster method for adjusting sand gradation without compromising ASTM quality standards. The proposed method involves analyzing six silica sand samples of different gradations, pre-screening sands, using Excel Solver for optimal mixture ratios, making automated gradation tweaks with precise calculations, and validating the gradation to ensure ASTM compliance. After making the adjustments, compressive strength tests were conducted on mortars with the modified sands, and the results were compared with those of standard-graded sand. Based on statistical analysis, the new method yielded reliable outcomes with compressive strengths similar to standard sands. This innovation offers a more efficient alternative, paving the way for streamlined practices in civil engineering.
