混凝土材料是当前世界上最为重要的土木工程材料之一。由于其具有成本低、耐久性好、本地材料利用率高等优点,在我国基础设施建设,如公路、桥梁、隧道等工程中得到广泛应用,为经济发展发挥了巨大的作用。近几年来,我国对基础建设方面的投资力度加大,尤其是在我国的西部地区更为的明显。各类项目工程的实施,让建筑材料得到了广泛的运用。在本文中研究的混凝土则是这些项目建设中最为重要的一种。我们都知道在我国的西部地区,气候环境不仅十分的恶劣,而且气温变化快,白天与夜晚的温差大,因此在这些劣势的环境中,对于混凝土材料的质量要求就十分的严格。
Concrete is one of the most important civil engineering materials in the world at present. Due to its advantages of low cost, good durability and high utilization rate of local materials, it has been widely used in China’s infrastructure construction such as roads, bridges and tunnels and has played a significant role in economic development. In recent years, China has made more investments in infrastructure construction, especially in the western region of our country. The implementation of various projects, construction materials have been widely used. The concrete studied in this article is the most important one of these projects. We all know that in our country’s western region, the climate and environment are not only extremely bad, but also the temperature changes rapidly and the temperature difference between day and night is large. Therefore, the quality requirements of concrete materials are very strict in these disadvantaged environments.
