Anti-leakage Properties of Highly Active Fly Ash Grout and Its Use in C u rtain Grouting

Abstract:

The highly active fly ash grout provides such advantages as fine grain, good permeability, reliable strength, durability, low cost, compared with common cement grout. The field practice has proved that the highly active fly ash grout can achieve good anti leakage effect and improve obviously the anti leakage quality of the dam foundation when used in water reservoir dam curtain grouting; therefore, it is an ideal anti leakage grout.
