Experiment Research on Plastic Strength of Grouting Materials of Desulfurization Denitration Ash

Abstract:

Derived calculation formula of plastic strength, and used mortar consistency instrument to determine plastic strength. Through experiment, the fly ash and silicon powder that desulfurized or denitrated as grouting materials, its change rules of plastic strength were studid under different water cement ratio and different dosage conditions. Results shows that, between the two factors of water cement ratio and dosage, the water cement ratio affect significantly the plastic strength. The smaller the water cement ratio, the more obvious the increase of the plastic strength as time growth. Early plastic strength of silicon powder grouts is growing rapidly.
