    摘要:

    建筑材料具有高强度和低密度的要求,有必要建立适合于优化选择其力学性能的评价指标。在密度和强度评估的背景下,提出了一种对建筑材料密度和强度进行综合评价的方法-密强法。基于密强法进行了不同材料之间的优选和同一材料不同参数之间的优选,研究了不同建筑材料的密度和强度参数在密强图的分布情况。结果表明:不同材料在密强图上的密强不同,在优选材料时可由密强图分别计算出各材料的相对密强改进量及改进角,进行比选;同一材料在不同参数下的密度与强度的表现不同,由密强图可对影响材料性能的因素进行优选;密强能综合反映建筑材料密度和强度的性质,是表达材料轻质高强性的一种直观易懂的方法。

    Abstract:

    Building materials have requirements of high-strength and low-density, and it is necessary to establish evaluation indexes that are suitable for optimizing the mechanical properties of building materials. Under the background of density and strength evaluation, a method for comprehensive evaluation of the density and strength of building materials, density-strength method, is proposed. Based on the density-strength method, the optimization of different materials and the optimization of different parameters of the same material are carried out, and the distribution of the density and strength parameters of different building materials in the density-strength diagram is studied. The results show that the density and strength of different materials is different on the density-strength diagram, and when selecting materials, the density-strength diagram can be used to calculate the relative density improvement amount and the improvement angle of each material for comparison and selection; the density and strength of the same material under different parameters are different, and the factors affecting the properties of the material can be optimized by the density-strength diagram; density and strength can comprehensively reflect the properties of density and strength of building materials, which is an intuitive and understandable method to express the lightweight and high strength of materials.
