混凝土是重要的建筑材料之一,在土木建筑工程与水泥制品的应用上主要是利用其抗压性能。混凝土虽有一百多年应用历史,但是,作为混凝土力学性能的一个基本问题——混凝土受压破损机理,至今还难以建立一个完整的理论和解释。多少年来,在实际工程上对混凝土的破损只能停留在强度标准的临界概念(或强度的极限概念),因此,影响了进一步挖掘混凝土的潜力、提高混凝土的承载能力。 Concrete is one of the important building materials. Its application in civil engineering and cement products is mainly due to its compressive properties. Although concrete has more than one hundred years of application history, it is still difficult to establish a complete theory and explanation as a basic problem of the mechanical properties of concrete—the mechanism of concrete damage. For many years, the damage to the concrete in the actual project can only stay in the critical concept of the strength standard (or the limit concept of the strength). Therefore, the potential for further excavation of concrete and the bearing capacity of the concrete are affected.
