Mesoporous material MCM-41 was prepared at room temperature,then rare earth ion Eu and semiconductors CdS were assembled in the channel of MCM-41.
在室温下制备介孔材料MCM-41,将稀土离子铕和半导体材料CdS组装到MCM-41孔道中,制得CdS/Eu-MCM-41复合介孔材料。
The effect of grouting of the ducts in the prestressed concrete structures is directly related to the corrosion of the prestressed reinforcement bars.
预应力混凝土结构中的孔道压浆效果,直接关系到预应力筋的防腐问题。
Due to the reducing the bleeding rate and shrinking rate of cement grout and increasing the compactness of the duct grouting,the safety and durability of prestressed concrete structure are improved.
真空辅助灌浆工艺是后张有粘结预应力混凝土结构施工中的一项新技术,采用该工艺施工有利于减小被灌水泥浆的泌水率和收缩率,增强孔道灌浆的密实度,从而达到提高预应力混凝土结构的安全度和耐久性的目的。
In the internal prestressing system constructed with post-tensioning method, the duct grouting is a procedure of considerable importance and is the major step to realize corrosion proof of prestressing strands.
在后张体内预应力体系中,孔道压浆是一项相当重要的操作,是实现预应力束防腐的主要措施。
