A comparative study of pH and temperature on rheological behaviour between Polyacrylamide (PAM) and its modified PAM

Drilling waste is a problem that affects the environment, society, and health. However, rheological additive in drilling fluid source of generation waste. Hence, suitable became concern bored pile construction. Conventional bentonite has been replaced by usage polymer operations, this due to operational, environmental, economic aspects. Unlike bentonite, polyacrylamide (PAM) high molecular weight, good gelling behaviour, eco-friendly. there are limitations PAM terms thermal stability pH sensitivity. Therefore, conventional polymer-based requires hybridisation functionalised material. In paper, with its enhancement needed for water-based through modification using silica (SiO 2 ) sodium dodecyl sulphate (SDS). The paper presented comparative analysis behaviour between modified PAM. This research involved influence temperature (ambient 80 °C) (9 10). Results revealed performed better at 40 °C 10. Furthermore, had performance Future studies can demonstrate as construction investigate frictional resistance fluid.
