“…Instead of using relative density as the controlled variable for the initial target condition, relative compaction was preferred to properly simulate site conditions. A value of 95% relative compaction was the target initial value in order to satisfy the desired in situ conditions [7], [11]. The extent of sea water exposure for the experiment has three conditions.…”

ABSTRACT:In the 2016 Annual Energy Sector accomplishment report of the Philippine's Department of Energy, power generation in the Philippines relied on the coal-fired power plant at 46%. An increase of 19.47% was observed from 2003 to 2016. The increase in demand would result in an increase in production of waste material from the power plant namely, coal ash. Furthermore, the disposal of these waste materials can be an issue because it can cause a shortage in storage facilities. To address this, there is a need to study on the possibility of reusing these waste materials. A probable use of the waste material is by using it as a construction material for road embankments. In the Philippines some of these structures are constructed on areas exposed to seawater in order to address traffic congestion. This study proposes to use coal ash as the material for road embankment. Triaxial test under consolidated drained condition was performed considering the exposure to seawater. Three conditions were implemented namely, no exposure, immediate exposure and prolonged exposure. Based on the results, 100% fly ash had the highest strength. The hyperbolic model was employed to simulate the material's stress-strain response. The hyperbolic model was chosen since it has the capability of predicting the load-displacement behavior of the waste material under monotonic loading. The Hyperbolic model prediction shows that the material can still handle higher stresses. With this, the ash mixtures tested has a potential to be used as a construction material for a road embankment.

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