Abstract: Heat of hydration and chemical shrinkage are some of the main causes of cracking in concrete. The heat of hydration and chemical shrinkage characteristics of cement pastes containing Sugarcane Waste Fiber Ash (SWFA) partially replacing cement by weight percentage of between 0 and 20% were investigated in this study using a Semi Adiabatic Method to BS EN 196 – 9:2010 for the heat of hydration, and a volumetric method to ASTM C 1608-07 for the chemical shrinkage. A maximum amount of shrinkage was observed on the paste containing 4% SWFA replacing cement by weight. This was thought to be caused by increased reactions at this SWFA content.
