Abstract

Research into lightweight structural concrete using volcanic tuff is of great importance to the construction industry. These materials have excellent thermal insulation properties, which helps improve the energy efficiency of buildings. A three-factor experimental design was used to build the statistical model. The test methods used were methods for determining the crushability of volcanic tuff, determining the average density, compressive strength and thermal conductivity of lightweight structural concrete. The influence of basalt fiber on the properties of lightweight structural concrete has been determined. The optimal compositions of lightweight structural concrete using tuff have been selected. The compressive strength of lightweight structural concrete reached 32.0 MPa. The average density range is 1754.6–2114.0 kg/m3. Good thermal conductivity values were obtained in the range of 0.653–0.818 W/m·K. The article obtained the optimal compositions of lightweight structural concrete using volcanic tuff as a filler.

利用三因素试验规划改进轻质结构凝灰岩混凝土成分

对使用火山凝灰岩的轻质结构混凝土的研究对建筑业具有重要意义。这些材料具有优异的隔热性能，有助于提高建筑物的能效。采用三因素实验设计来建立统计模型。使用的试验方法包括测定火山凝灰岩可压碎性的方法、测定轻质结构混凝土平均密度、抗压强度和导热系数的方法。确定了玄武岩纤维对轻质结构混凝土性能的影响。选定了使用凝灰岩的轻质结构混凝土的最佳成分。轻质结构混凝土的抗压强度达到 32.0 兆帕。平均密度范围为 1754.6-2114.0 kg/m3。导热系数范围为 0.653-0.818 W/m-K。文章利用火山凝灰岩作为填料，获得了轻质结构混凝土的最佳成分。
