The main objective of this work was to investigate the influence of waterborne epoxy resin emulsion (WER) on the physical properties of oil well cement slurries. Cement slurries containing 5%, 10% and 15% of WER bwoc were compared with WER-free slurries. The rheological behavior was carried out according to API standard. Uniaxial compressive strength and shear bond strength of cement stone were evaluated at the ages of 24, 48 and 72 h. The experimental results illustrate that the addition of WER does not alter the rheological behavior. The addition of WER has increased the shear bond strength almost 52% at 24 h of aging for 10% WER bwoc when compared with unmodified slurry. The enhancement on shear bond strength was attributed to the mechanical anchoring and resin film forming at the interface.

Objektif utama penyelidikan ini adalah untuk mengkaji pengaruh emulsi resin epoksi bawaan air (WER) ke atas sifat fizikal sluri simen telaga minyak. Sluri simen yang mengandungi 5%, 10% dan 15% WER bwoc dibandingkan dengan sluri tanpa WER. Tingkah laku reologi telah dijalankan mengikut piawai API. Kekuatan mampatan unipaksi dan kekuatan ikatan ricih batu simen telah dinilai pada umur 24, 48 dan 72 jam. Keputusan kajian menunjukkan bahawa penambahan WER tidak mengubah tingkah laku reologi. Penambahan WER telah meningkatkan kekuatan ikatan ricih hampir 52% pada umur 24 jam untuk 10% WER bwoc apabila dibandingkan dengan sluri tidak diubah suai. Peningkatan pada kekuatan ikatan ricih adalah disebabkan oleh yang tambatan mekanik dan resin filem yang membentuk di antara muka.
