Abstract
Water composition during cement hydration can be changed due to migration of ions from the cement matrix to the solution. The storage of various materials together can lead to transfer of various ions and distortion of results. This article is aimed on the influence of storage environment on the Portland cement hydration and hydrated samples composition. Test specimens were prepared and stored in different environments. Storage environments were ultrapure water and solutions having alkaline and acidic pH value. The mechanical properties were measured after 1, 7 and 28 days. Composition of samples stored in different environment was tested by X-ray diffraction and DTA analysis. (C) 2016 Published by Elsevier Ltd.
