These waste<br>materials most of the time is kept in storage facilities. Due to the growing demand in electricity generation,<br>storage facilities can no longer accommodate the waste materials. Instead of disposing the waste materials, it<br>can be used as a construction material. A promising civil engineering structure that can use coal ash as a<br>construction material is land reclamation. The structure needs huge volume of materials and this can<br>maximize the usage of coal ash. In the Philippines, most land reclamation projects are conducted at the sea.<br>From this, distilled water was replaced with sea water to have a better evaluation of the strength properties of<br>coal ash. Consolidated drained test was performed having three conditions with respect to sea water exposure.<br>First condition is no exposure, second condition is immediate exposure and third condition is prolonged<br>exposure. Results show that coal ash exposed to seawater, immediate and prolonged, has smaller shear<br>strength. On the other hand, it still has reasonable strength suitable for land reclamation projects. Constitutive<br>modeling using Modified Cam Clay model is incorporated in the study to be able to predict its behavior and<br>failure in terms of mean effective stress, deviator stress and specific volume.<br><br></p>}, number={31}, journal={GEOMATE Journal}, author={Erica Elice Saloma Uy and Jonathan R.
