Depending on the dimensions of concrete elements, aggregates of different grain sizes are used for the building structures. Taking this fact into account, the authors of the paper have undertaken in their work an issue concerning the analysis of the influence of maximum aggregate grain size on the strength properties and modulus of elasticity of concrete. This is also due to the fact that few published research results are available in this area. In this paper, the influence of the maximum grain size on the basic strength and deformation properties of concrete is discussed. The research concerns both concretes and gravel aggregates used for their construction with maximum grain sizes of 8 mm, 16 mm and 31.5 mm. The values of the compressive and splitting tensile strength, brittleness and modulus of elasticity of concretes with w/c = 0.45 were analysed. The analysis showed that the strength properties are proportional not only to the maximum size of aggregate grain, but also to the crushing strength of the aggregate. There were no analogous relations found with respect to the modulus of elasticity of the tested concretes. Tensile strength was particularly susceptible to the observed changes.

最大骨料粒度对混凝土强度特性和弹性模量的影响

根据混凝土构件的尺寸，不同粒度的骨料用于建筑结构。考虑到这一事实，该论文的作者在他们的工作中进行了有关分析最大骨料粒度对混凝土强度特性和弹性模量的影响的问题。这也是由于该领域很少有已发表的研究成果。本文讨论了最大粒径对混凝土基本强度和变形性能的影响。研究涉及用于建造的混凝土和砾石骨料，最大粒度为 8 毫米、16 毫米和 31.5 毫米。w/c=0时混凝土的抗压和劈裂抗拉强度、脆性和弹性模量的值。分析了 45 个。分析表明，强度特性不仅与集料颗粒的最大尺寸成正比，而且与集料的抗压强度成正比。在测试混凝土的弹性模量方面没有发现类似的关系。拉伸强度特别容易受到观察到的变化的影响。
