CHEMICAL ADDITIVES FOR ACCELERATING THE SETTING AND HARDENING OF GUNITE

FOR GUNITE (PNEUMATICALLY PLACED CONCRETE) IT IS NECESSARY TO USE ADDITIVES TO THE VARIOUS CEMENTS FOR ACCELERATING THEIR SETTING. SUCH ADDITIVES SHOULD BE SO SELECTED THAT, ON THE ONE HAND, THEY ENABLE THE DESIRED SETTING TIME TO BE ACHIEVED BUT, ON THE OTHER HAND, DO NOT ADVERSELY AFFECT THE SUBSEQUENT STRENGTHS NOR INDEED CORROSIVELY ATTACK THE REINFORCEMENT. SOME OF THE USUALLY EMPLOYED ADDITIVES WERE INVESTIGATED WITH REGARD TO THIER EFFECT ON PORTLAND CEMENTS OF VARIOUS COMPOSITION, AND IT WAS ESTABLISHED WHAT COMPOSITION A PORTLAND CEMENT SUITABLE FOR GUNITE SHOULD HAVE. /AUTHOR/
