摘要
Effect of Rice husk ash on hydration properties of rice husk ash cement paste are reported in this paper.Rice Husk Ash (RHA) is used to replace 20% of Portland cement and water to solid ratio is 0.4.The hydration products observed due to rice husk ash addition were confirmed using the characteristic peak of Fourier Transform Infrared (FTIR) spectra and the micro structural changes were noted using Scanning Electron Microscope (SEM) micrographs.The rice husk ash cement paste gains more strength due to the production of more Calcium Silicate Hydrate (CSH) gel (pozzolanic reaction products).
