Effect of Magnetite Nanoparticles on Cement Based Composite

Abstract

There has been a rapid increase in interest in nanotechnology and nano particles. Nanotechnology has been increasingly brought into the study of cement-based materials in the recent years. Adding nanosized particles in small amounts as materials can affect their properties significantly. In this study, the effect of nano magnetite Fe3O4/humic acid mixture (used as addition of 0.1, 0.5, 1, 1.5, 2, 3, 4 and 5% in mass of the cement) on the microstructural development and mechanical properties of cement composites has been investigated. Hence, samples size of 40.40.160 mm were produced using obtained cement based composites. After 28th days, flexural and compressive strength and water absorption experiments were implemented for cement based mortar samples. The microstructural analysis of mixtures nanoparticles were performed by scanning electron microscopy. Results were compared with the reference composite. As a result, 1% substitution nanoparticles with cement supplied best performance in terms of strength, water absorption.
