再生混凝土纳米复合强化试验
Recycled Concrete Intensified by Nano-materials
摘要
Abstract
Experimental research on the performance of recycled concrete intensified by highly active nanoSiO2 and nano-mineral admixture was carried out, mainly on the mechanical properties, the anti-chloride ion permeability and the impermeability of recycled concrete affected by highly active nanoSiO2 and nanomineral admixture. Results show that the compressive strength of recycled concrete increased obviously with nano-mineral admixture, 16.8％ at 14 days and 16. 3％ at 2.8 days. Nano-mineral admixture mixed with 1％ nanoSiO2 showed a good composite effect. The compressive strength of recycled concrete increased greatly, especially for the late strength, about 18％ at 28 days. The anti-chloride ion permeability of recycled concrete improved significantly as the total electric flux reduced by 35 ％. The impermeability of recycled concrete also significantly improved as the impermeability grade was higher than P10.关键词
