Advanced Early Strength Agent Development and Mechanism Analysis
Preparation of advanced early strength agent ,the main components including organic A, organic B and calcium nitrate. Then tested advanced early strength agent performance for concrete. Though text, we find, the compressive strength and flexural strength of the specimen, use of the advanced early strength agent is greatly improved than with its much better not to use advanced early strength agent. With the passage of time, advanced early strength agent added does not make the strength of concrete worse, but better.Use SEM and XRD analysis technology text advanced early strength agent by adding performances of concrete, including the degree of cement hydration, the morphology of hydration products and the composition of mineral formation. analysis of the role of advanced early strength agents from the perspective of the mechanism. Identified advanced early strength agent impact on the cement hydration, for the further development of early strength agent to provide a theoretical basis.
