THE EFFECT OF CEMENT COMPOSITION ON STRENGTH, SETTING TIME, AND SLUMP LOSS OF CONCRETE CONTAINING A LIGNIN-TYPE WATER-REDUCING SET-RETARDING ADMIXTURE,

Abstract

This study is an attempt to detect effects of chemical composition of cement on compressive strength, time of set, and rate of slump loss when a ligno-sulfonic acid type water-reducing, set-retarding admixture (WRA) is used in manufacturing concrete. Such studies are difficult due to the formation of numerous complex hydrates during the cement-water reaction. The addition of another substance to the system, such as a water-reducing, set-retarding agent, further complicates an already intricate system. This research attempts only to define certain effects of cement composition on the properties of concrete when the additive is used, rather than explain the mechanism of the chemical reactions taking place.
