混凝土与钢筋混凝土是当前我国建筑工程中应用最广泛的一种建筑材料，主要原因是它可以满足大跨度、高层、负重、耐久、易成型等多方面建筑功能的要求，特别是在框架结构工程的柱、梁板中大量采用，所以，工程可靠度直接受到混凝土质量的影响。混凝土强度不足和缺陷造成的危害 Concrete and reinforced concrete are the most widely used building materials in China’s current construction projects. The main reason is that it can meet the requirements of large-span, high-rise, weight-bearing, durable, easy-to-shape and many other architectural functions, especially in the framework of structural engineering. The pillars and beams are widely used, so the engineering reliability is directly affected by the quality of the concrete. Insufficient concrete strength and defects caused by defects
