采用棱镜试件（40mmx40mmx160 mm），研究了密度为1100 kg/m(3)至1800 kg/m(3)的砂基加气轻质混凝土（ALC）和土基加气轻质混凝土（SALC）在不同水泥掺量（填料：粘结剂= 1:1、1:1.5和1:2）下的抗压和抗弯强度。120 d试验结果表明，在相同密度和水泥掺量下，ALC的抗压强度比SALC高3.6% ~ 79.4%，抗折强度比SALC高3.7% ~ 137.0%。然而，基于其强度特性，土壤仍然适合用作生产加气轻质混凝土的替代材料。建立了加气轻质混凝土强度特性与控制因素之间的多元回归模型。分析发现，密度对加气轻质混凝土强度性能的影响最大，其次是龄期。
The compressive and flexural strengths of sand-based Aerated Lightweight Concrete (ALC) and Soil-based Aerated Lightweight Concrete (SALC) of density 1100 kg/m(3) to 1800 kg/m(3) with different cement content (filler:binder = 1:1, 1:1.5 and 1:2) were investigated using prism specimens (40 mmx40 mmx160 mm). The results on the 120-day, indicated that the strength properties of ALC outperformed SALC by the range of 3.6% to 79.4% on compressive strength and 3.7% to 137.0% on flexural strength for identical density and cement content. Nevertheless, soil is still suitable to be used as an alternative material for the production of aerated lightweight concrete based on their strength properties. Multiple regression models were developed to correlate the strength properties of aerated lightweight concrete and its governing factors. From the analysis, it is found that density has the greatest influence on the strength properties of aerated lightweight concrete, followed by the age of the specimens.
