Synthesis of New Fly Ash Composite Materials and its Influence on Compressive and Flexural Strength of Concrete
Asian Journal of Chemistry,
Vol. 28 No. 10 (2016): Vol 28 Issue 10
Abstract
This article reports the fabrication of the new fly ash composite materials using surface-initiated atom transfer radical polymerization (ATRP) technique. The surface of fly ash were densely grafted with 2-(3,4-epoxycyclohexyl)ethyltrimthoxysilanol (KH566) and then opened ring reaction with poly(itaconic acid-co-acrylic acid) via two methods. Structural properties of the new fly ash composite materials are investigated by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and thermogravimetric analysis. The new fly ash composite materials not only increase significantly the compressive strength of the fly ash concrete, but also increase the flexural strength of the fly ash concrete. New fly ash composite materials are integrated with cement-based building materials, the new fly ash composite materials possess some outstanding properties, which leads to vast potential applications in reinforcing the strength of concrete.
