摘要
新型泡沫轻质混凝土因轻质、卓越和可持续特性,越来越多地被应用于现代工程领域。尤其在高等级路基拓宽中,运用新型泡沫轻质混凝土,可以显著提高路基的承载能力,减少对地基的压力。然而,在其施工中,经常面临新旧路基的沉降差异,使得泡沫轻质混凝土混合不均,后期养护出现开裂、吸水等问题,影响项目的施工成本和施工工期。基于此,文章概述了新型泡沫轻质混凝土,研究了高等级路基拓宽中新型泡沫轻质混凝土施工存在的问题,提出了具有针对性的优化措施。
New foamed lightweight concrete is increas-ingly used in modern engineering due to its lightweight,excellent and sustainable characteristics.Especially in the widening of high-grade subgrade,the use of new foamed lightweight concrete can significantly improve the bearing capacity of the subgrade and reduce the pressure on the foundation.However,in the construction,it is often faced with the settlement difference between the old and new subgrades,which makes the foamed lightweight concrete unevenly mixed and causes problems such as cracking and water absorption in the later maintenance,affecting the construction cost and construction period of the project.Based on this,this paper outlines the new foamed light-weight concrete,studies the problems existing in the con-struction of new foamed lightweight concrete in the wid-ening of high-grade subgrade,and puts forward targeted optimization measures.
