Sari IAU Researchers Cement Based Materials with Nanoparticles

Tuesday, December 26, 2017 - 11:13

Researchers from Islamic Azad University, Sari branch, University of Mazandaran, Babol Noshirvani University of Technology and Tabari University of Babol have cement based material through using nanoparticles which leads to the reduction of cement consumption.

According to an ISCA report, nowadays, sustainable development policies seek solutions to reduce environmental pollution. In this regard, the combined effects of different percentages of nano-Montmorillonite and nano-Titanium (nano-MT) particles on the improvement of mechanical and microstructural properties of hardened cement considering managerial and environmental aspects of reducing cement consumption were evaluated in this study.

One of the researcher, Aref Sadeghi-Nik explained that two kinds of nanoparticles have been used in this project to improve mechanical properties and microstructure of Portland cement as well as reducing environmental pollution.

The replacement ratios of Portland cement with the same weight of nano-MT particles are 1, 2 and 3 weight percent (wt%). The mechanical properties of cement mortar and microstructural properties of hardened cement paste were investigated using Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM) and Energydispersive X-ray spectroscopy (EDS) techniques.

The results show that replacement of cement with nano-MT particles up to 1 wt% as an optimum percentage can improve microstructure and mechanical properties of cement significantly. Moreover, using nano-particles is one of the efficient approaches to reach sustainable development in construction industry that can contribute to decrease the pollution caused by cement production and consumption.
