摘要
Abstract
The crushed basalt sand was used for construction of Guandi hydropower project. The experimental study of the surface powder coat characteristics of the crushed basalt sand and its impact on the roller compacted concrete performance shows that its surface coat has great impacts on compressive strength, ultimate tensile value and shear strength of the roller compacted concrete. All of the performance indicators of the roller compacted concrete was effectively improved by optimizing crushed sand production processing technology and reducing the content of harmful microparticle sand powder, thus satisfying the requirements of both design and specifi cations.关键词
