09 Jan Fly Ash Philippines: The 2020 New Green Initiative
In the past several years, fly ash Philippines has been introduced and used as an additive to cement. Cement batching plants nationwide and all over the world use fly ash to improve the strength of concrete mix. When used as a Portland cement replacement, the class F fly ash shows increased resistance to sulfate attack, increased late compressive strengths, after approximately 28 days, increased resistance to alkali-silica reaction (ASR), and increased pore refinement, as compared to unmodified Portland cement.
Fly Ash Philippines
In recent years, the global construction market has been creating a paradigm shift of creating a more sustainable and greener approach to development with the use of fly ash. This shift in the market has enabled the demand for fly ash to become an additive in a wide variety of uses in the construction field.
Currently, more than 50 percent of the concrete placed in the U.S. contains fly ash. In the Philippines, statistics are currently unavailable regarding the use of fly ash. Dosage rates vary depending on the type of fly ash and its reactivity level. Typically, Class F fly ash is used at dosages of 15 to 25 percent by mass of cementitious material, while Class C fly ash is used at dosages of 15 to 40 percent.
Fahrenheit Company Limited (FCL) has been supplying fly ash in the Philippines and the Pacific Islands since the 2000s. We aim to provide the global fly ash market while giving importance to the development of the Philippines. The construction market in the Philippines is in demand for fly ash due to the Build! Build! Build! Movement. However, the quality of this commodity has significantly decreased as the fly ash produced in the Philippines does not meet global standards. To bridge the gap between the world and the local standards, FCL has continuously maintained the quality of fly ash we provide to our clients to meet international standards.

2020 Green Initiative
Starting late 2018 until the end of 2019, FCL was forced to cease the distribution of fly ash due to our source’s quality issues. During that time, we have created ties with international sources that meet not only the fly ash Philippine standards but also globally. In 2020, we want to increase the green initiative of construction supplies in the Philippines while still maintaining quality.
The Build! Build! Build! movement of the Duterte administration has created a shortage of construction supplies. However, the cement batching plants in the Philippines cannot increase production without the necessary raw materials. This challenge also includes production costs. Without fly ash, concrete mixes are expensive and are considered less sustainable and increasing the impact on our overall environment.
Fly ash is also recognized as an environmentally friendly material because it is a byproduct and has low embodied energy, a measure of how much energy is consumed in producing and shipping a building material. By contrast, Portland cement has a very high embodied energy because its production requires a great deal of heat.
In conclusion, the utilization of fly ash in building materials has many advantages. According to the Department of Transportation in the U.S., “Fly ash utilization, especially in concrete, has significant environmental benefits including: (1) increasing the life of concrete roads and structures by improving concrete durability, (2) net reduction in energy use and greenhouse gas and other adverse air emissions when fly ash is used to replace or displace manufactured cement, (3) reduction in amount of coal combustion products that must be disposed in landfills, and (4) conservation of other natural resources and materials.”
