1目前膨胀剂在应用中存在的问题膨胀剂的主要作用是减少混凝土结构产生的收缩裂缝。但是造成混凝土结构裂缝的原因除了材料因素之外,还有结构设计、施工等因素,非仅靠膨胀剂所能解决。具体而言,在应对早期冷缩方面,现有的膨胀剂无论从矿物成分构成,还是混凝土配合比应用技术等方面还有很多工作需要研究。就钢筋混凝土而言,抵御收缩裂缝,混凝土只是一个组分,钢筋的作用尤其重要。现在很多工程都要进行结构优化设计,力求最大限度减少钢筋
A current expansion agent in the application of the problem Expansion agent’s main role is to reduce shrinkage cracks in concrete structures. However, the causes of concrete structure cracks in addition to material factors, there are structural design, construction and other factors, not only by expansion agent can be solved. Specifically, in terms of dealing with early shrinkage, there is still much work to be done on the existing expansive agents in terms of mineral composition and application of concrete mix. In the case of reinforced concrete, concrete is only a component against shrinkage cracks and the role of reinforcing steel is of particular importance. Now many projects have to carry out structural optimization design, and strive to minimize the reinforcement
