Abstract
Pozzolanic cement compositions and method manufacturing the same are described. These cement compositions may include a pozzolanic material and an activator based on a salt of glycolic acid, glyceric acid, malic acid, tartaric acid, malonic acid, glutaric acid, maleic acid, formic acid, acetic acid, propionic acid, or butyric acid, a retarder based on hepto-gluconates, sulfate salts, sugars, sugar acids, lignins, and/or an accelerator based on amines. The cement compositions may have less than 10% by weight Portland cement. The pozzolanic cement compositions including these activators, accelerators, and retarders can have improved properties such as longer setting time, better slump retention, and improved strength.
