摘要
集料在水泥基材中具有重要的作用。混凝土材料中集料相与基体相对水泥基材料力学性能具有协同作用,表现出复合材料的力学行为。本文主要从集料品种、最大粒径、粒形、级配、碱活性等方面对混凝土强度、弹性模量及变形等方面的影响规律进行阐述。
Aggregate plays an important role in cement-based materials. Among the concrete materials, there is a synergetic effect between matrix phase and aggregate phase on the mechanical properties of cement-based materials, which shows the composites＇ mechanical behaviors. In this paper the effect principles of concrete strength, elastic modulus as well as deformation etc. were expounded from the category, max dimension, shape, grade and alkali activity of aggregate and so on..
