Kaolin Residue as an Alternative Binder for Grout Seat and Revetment

Abstract:

The kaolin residue presents in its composition significant levels of sílica and alumina, making it a material with chemical and physical properties appropriate to use as an alternative material with pozzolanic characteristics in substitution to the cement for grout utilization. Thus, this work aimed evaluate the influence from the addition of different amounts of kaolin residual calcined in partial substitution of Portland cement on grout in dash 1:2:6 (cement+%residue:lime:sand). It was evaluated grouts with and without residue substitution in the strengths of 0%, 5% and 30%, through resistor the simple compression at 30, 60 and 90 healing days. The results of resistor from the grouts were over the one required by NBR 13281 [, classifying them as type I e II.
