Effect of Silica Sand Filler on Mechanical Properties of Epoxy Grout for Composite Repair of Steel Pipelines

CODEN: MPCACD

Abstract

Oil and gas pipes are vulnerable to failure initiated by corrosion because of their operating pressure under adverse conditions. A composite repair assembled around the pipe with a small gap that is then infilled with epoxy grout is considered a suitable option for repairing corroded pipelines. This article presents an investigation into the mechanical properties (compressive, tensile, and flexural) of epoxy grout, with and without inclusion of silica sand as a filler. The mechanical tests were carried out in accordance with American Society for Testing and Materials standards. Experimental results on mechanical properties indicate that the strength in tensile and flexural mode for the grout decreases with the inclusion of filler because of a weak interface between the matrix and filler. However, the addition of filler in grout showed an increase in compressive, tensile, and flexural modulus. Based on suggested properties in a previous study, both grouts have the potential to be used on structural rehabilitation, especially for repairing damaged pipeline.
