Structural Features of Nanomodified Cement Stone
Journal Title: Architecture and Engineering - Year 2016, Vol 1, Issue 1
Abstract
The article reviews the effect of mixing water pre-modified with fulleroid nanomaterial on cement paste rheology and cement stone structure. Also pH value of modified mixing water is determined and its variation under the effect of nanomaterial is shown. Typical acidulation of obtained slurry is noted and time of its activity (aggregative stability) beneficial to formation of cement stone structure is determined. Analysis of the obtained results is evidencing changes in properties of cement systems prepared with the use of nanostructured water, namely increase in cement paste setting time and improvement of its fluidity with rheological properties maintained; enhancement of pore structure with improved uniformity of distribution throughout the volume, leading to increase in strength properties of cement stone.
