Effect of Fly Ash and Silica Fume on the Mechanical Properties of Cement Paste at Different Stages of Hydration

Abstract

This thesis investigates the effect of fly ash and silica fume on cement paste hydration. Percentages of each additive will replace the cement by volume to be studied at five ages. These percentages will be compared alongside a controlled cement paste without additives. Testing will be carried out on 350 samples. The testing methods used are a Forney Universal Testing Machine and MTS Landmark Servohydraulic Testing System (MTS) for compressive strength on cylinders and cubes, respectively. Fourier Transfer Infrared Spectroscopy (FTIR) monitored the hydration with spectra, and Scanning Electron Microscope (SEM) generated images for regional analysis.
