【摘要】 为研究彩色陶粒混凝土的抗冻性能，本文对红色颜料不同掺量的彩色陶粒混凝土试件进行了300次冻融循环试验，并计算其质量损失率与相对动弹性模量；在此基础上，建立了彩色陶粒混凝土质量损失率、冻融损伤经验模型，并运用响应曲面法综合分析了冻融循环次数、红色颜料掺量对彩色陶粒混凝土质量损失率和冻融损伤度的影响程度。研究结果表明：掺加红色颜料可有效增强陶粒混凝土的抗冻性能。更多还原

【Abstract】 In order to study the frost resistance of colored ceramsite concrete, 300 freeze-thaw cycle tests were carred out on colored ceramsite concrete specimens with different red pigment contents to measure and calculate their mass loss rate and relative dynamic elastic modulus. On this basis, the empirical model of mass loss rate and freeze-thaw damage of color ceramsite concrete was established, and the influence of freeze-thaw cycles and red pigment content on mass loss rate and freeze-thaw damage degree of colored ceramsite concrete was comprehensively analyzed by response surface method. The results show that the addition of red pigments can effectively enhance the frost resistance of ceramsite concrete.更多还原
