粉煤灰和陶粒对混凝土路用性能的影响分析
|
摘要
为研究粉煤灰和陶粒对混凝土路用性能的影响,针对不同粉煤灰和陶粒掺量的混凝土,对其抗压、耐磨、抗渗以及抗冻融等路用性能进行了试验测试分析。分析结果表明:粉煤灰的掺入能够有效提高陶粒混凝土的抗压、耐磨、抗渗以及抗冻融性能;而陶粒的掺入却会在增大粉煤灰混凝土抗渗以及抗冻融性能的同时降低粉煤灰混凝土的抗压和耐磨性能;当粉煤灰掺量为20…%、陶粒掺量为30…%时,粉煤灰陶粒混凝土的路用性能相对最佳。
In order to study the influence of fly ash and ceramsite on concrete road performance, the road performance of compressive,wear-resistant, impermeability and freeze-thaw resistance was tested in different fly ash and ceramsite contents. The analysis results show that:The incorporation of fly ash can effectively improve the compressive, wear-resistant, impermeability and freeze-thaw resistance of ceramsite concrete. While the incorporation of ceramsite will increase the anti-seepage and anti-freeze-thaw properties of fly ash concrete, and reduce the compressive and wear resistance of fly ash concrete. When the fly ash content is 20 % and the ceramsite content is 30 %, the road performance of the fly ash ceramsite concrete is relatively optimal.
