A scientifically accurate detection method of efflorescence on cement-based decorative mortars is presented in this paper after five different efflorescent detection tests. According to this method, the influence of different content of diatomite on prevention of efflorescence on decorative mortars was mainly investigated. Water absorption and basic mechanical properties of the decorative mortars with addition of diatomite were also explored. Subsequently, thermogravimetric and nitrogen adsorption method were applied to explain the mechanism of restraining efflorescence. It was found that appropriate amount of diatomite could effectively inhibit the efflorescence of decorative mortars.

水泥基装饰砂浆泛光检测及抑制方法研究

本文通过五种不同的风化检测试验，提出了一种科学准确的水泥基装饰砂浆风化检测方法。根据该方法，主要考察不同硅藻土含量对装饰砂浆防风化的影响。还研究了添加硅藻土的装饰砂浆的吸水率和基本力学性能。随后，应用热重法和氮吸附法解释了抑制风化的机理。研究发现，适量的硅藻土可以有效抑制装饰砂浆的风化。
