硅粉微膨胀混凝土在渔洞水库溢流建筑中的应用

Application of Ganister Sand Concrete with Microdilatability in the Spillway Structure at Yudong Reservoir

云南昭通渔洞水库泄洪建筑物均采用硅粉微膨胀混凝土作为抗冲磨材料，总方量近１万ｍ３，为此进行了试验研究。本文介绍了试验结果，并在此基础上叙述了硅粉微膨胀混凝土的设计情况和施工效果。

As a scour resistance and antiwear material, the ganister sand concrete with microdilatability was used in the flood discharge structure at Yudong Reservoir, Zhaotong, Yunnan Province. The total amount of it was nearly 10000 m 3. Study and test were carried out. The design, test results, conditions of construction of ganister sand concrete with microdilitability are introduced in this paper.
