Effective Use of Lithium-Based Admixtures for Set Control of Cementitious Systems

Abstract

This paper describes the development and applications of several lithium-based chemical admixtures for set control of cementitious based construction and building materials. Comparative evaluations show the effect of these admixtures on the set time of (1) calcium aluminate cement; (2) portland cement; and (3) blended systems of calcium aluminate cement and portland cement. General information is provided to address the principles of material selection, dosage rate and application of cementitious systems.
