摘要
在高速公路路基拓宽的工程中,使用新型泡沫轻质混凝土并对其施工工艺流程、输送方式、距离、分层与分区、模板、浇筑与养护方法等因素进行试验。结果表明:与普通填料相比,新型泡沫轻质混凝土有着更为突出的强度,压实度优势也比较明显,底部抗滑稳定安全系数高,但不得在空气中暴露,应合理选用防护与防排水措施。…
New light weight foam concrete is usually used to widen the expressway subgrade. The construction technology process of new light weight foam concrete including delivery mean, delivery distance, layering, partition is carried out. The results show that, new light weight foam concrete has a higher intensity and compactness than normal filler, it has a high bottom skid stability, while, it cannot exposed to air.
