摘要：

The paper studied effect of alklia activators such as gypsum and sodium sulfate on blended cement made from slag, and analysised hydration products, micro properties by X-ray diffraction, nitrogen adsorption, etc. Prepared a series of concrete by means of adjusting water to binder ratio, the content of alkali-activated slag. Test results show that the concrete has higher flexural strength (flexural strength exceeds 7.0 MPa with the content of slag being 30%), outstanding durability, and expecially suitable for building pavement that demands high flexural strength.
