In total, 16 mixes were prepared by replacing cement using GGBS up to 50% and river sand by pond ash up to 30% …

About 2% addition of cement to pond ash makes it suitable for geotechnical applications, especially as a subgrade material for pavements. This is ascertained by finding the resilient modulus of cemented pond ash. The resilient modulus was also predicted using Uzan and National Cooperative Highway Research Program (NCHRP) models.

Finally, based on the above observations, it is concluded that the prepared model is efficient in the development of the ANN model for the 28-day Compressive strength of Pond ash Concrete. With such predictions can be done quickly. This relation can be used to assess the compressive strength of pond ash concrete for different percentages of doses.

In this study, an attempt was made to use pond ash (PA), which is an industrial waste generated in power plants, as a replacement for fine aggregates (FA) in concrete. An experimental program was conducted on the mechanical properties (compressive strength, split-tensile strength, and flexural strength) of pond ash concrete.

The fly ash over the years is being used to produce pozzolanic cement and fly ash bricks. The pond ash consists of the unburnt coal slurry transported into ponds. The pond ash is stored in huge quantity and still demanding land for disposal. The non-availability of land for disposal establishes the need of using pond ash as resource material.

Pond ash is sourced from the Eraring power station in Australia and classified as class-F (low calcium) pond ash, adhering to ASTM C618–19 Standards. Table 1 presents the chemical composition of both GP cement and pond ash, determined using X-ray fluorescence. A commercially supplied GP cement is utilized for brick mixes.

Kumar and Gupta considered the consequence of fibre reinforcement using polypropylene fibre and soil stabilization using cement on the geotechnical properties of a soil stabilized with combination of pond ash and rice husk ash (RHA). Samples were made with varying content of pond ash from 30 to 45% of the dry weight of the soil, where the total ...

However ash in ponds is coarser and doesn't meet the aforementioned criteria thus grinding or milling techniques using ball or hammer mills are used to improve the fineness of PA. Particle size distribution curve of as-received and milled pond ash is shown in Fig. 6. It can be noticed from the figure that as-received PA displayed non-uniform ...

Five CLSM mixtures were prepared using pond ash with varying cement (3–7%) to achieve the desired strength of 0.7 MPa at constant flowability of 300 mm. Flowability was measured before the preparation of the UCS sample. All CLSM samples were prepared in 38 mm diameter and 76 mm height moulds. CLSM samples are cured at a temperature of 30 °C ...

In total, 16 mixes were prepared by replacing cement using GGBS up to 50% and river sand by pond ash up to 30% in tandem. From the different mixes cast, an optimized green concrete mix with GGBS and pond ash was selected based on the performance of fresh (slump test) and hardened properties (compressive strength).
