含气量对混凝土性能的影响是多方面且非常复杂的,含气量不仅会影响混凝土的和易性,而且还会影响混凝土的抗压强度、抗冻性能,此外还会影响混凝土的耐磨性、热传导性、自身变形等。适当的含气量可在很大程度上提高混凝土的综合性能,但若含气量不合理则会影响混凝土质量,进而影响施工质量,为此,必须严格控制混凝土含气量。文章以具体的实验分析了混凝土含气量对抗压强度和抗冻性能的影响。
The influence of gas content on the performance of concrete is multifaceted and very complicated. The gas content not only affects the workability of concrete, but also affects the compressive strength and frost resistance of concrete. In addition, it also affects the wear resistance of concrete, Thermal conductivity, self-deformation and so on. Appropriate gas content can greatly improve the overall performance of concrete, but if the gas content is unreasonable will affect the quality of concrete, thus affecting the construction quality, therefore, we must strictly control the air content of concrete. In this paper, the influence of concrete air content on compressive strength and frost resistance is analyzed with concrete experiments.
