Epoxy Emulsion Modified Engineered Cementitious Composite for Enhanced Pipeline Coating

Abstract:

A new class of Epoxy Emulsion modified Engineered Cementitious Composite (EM-ECC) has been developed for enhanced pipeline protection. The performance of typical ECC materials, such as flexural strength, anti-corrosion and early strength, has been improved by the addition of epoxy emulsion and rapid hardening cement. Our results indicated that the flexural strength of as-made EM-ECC increases with the increase of the EM/cement ratio after curing for 28 days. The retention rate of flexural strength of specimens remains analogical after immersed in water, 5 wt% Na₂SO₄ and 5 wt% NaCl solutions, respectively. The flexural strength reached ca. 16 MPa at 60 wt% replacement rate of rapid hardening cement after curing for 3 days. This new class of EM-ECC will shed light to the design of new applications for the oil and gas industry.
