由于混凝土因其取材广泛、价格低廉、抗压强度高、可浇注成各种形状,并且耐火性好、不易风化、养护费用低,成为当今世界建筑结构中使用最广泛的建筑材料之一。但同时自身也存有一些缺点,如自重大、离散性大、容易产生裂缝,尤其以裂缝为突出。它也成为长期困扰着我们工程技术人员的头痛问题。根据现场工程实践,并经长时间的观察、总结,现提出几点与大家探讨。 Due to its wide range of materials, low cost, high compressive strength, pourability into various shapes, and good fire resistance, weather resistance, and low maintenance costs, concrete has become one of the most widely used building materials in the world today. But at the same time, it also has some shortcomings, such as self-heavy, discrete, prone to cracks, especially in the cracks. It has also become a headache that has long plagued our engineering and technical personnel. According to the on-site engineering practice, and after a long period of observation and summary, several points are now proposed to discuss with you.
