在设计砌筑砂浆配合比时,如何合理掺用粉煤灰的计算资料少见。一般在选砂浆配合比时,是以配合比试验结果,用综合对比评定法,选取接近设计要求的配合比,其后果往往是标号偏高,因而浪费材料不尽科学。我们利用《新型建筑材料》杂志中提供的配合比试验资料,经分析整 When designing masonry mortar mix ratio, the calculation data of how to use fly ash rationally is rare. Generally, when selecting the mortar mix ratio, it is based on the results of the mix ratio test. With the comprehensive comparison and evaluation method, the mix ratio close to the design requirements is selected, and the consequence is that the labels are often high, thus wasting material is not scientific. We use the test data of the mix ratio provided in the “New Building Materials” magazine and analyzed
