Experimental production of unburnt bricks using coal mining waste and fly ash in Vietnam shows improved properties.

Dry bulk density measures 2176 kg/m³ for CP1 and 2192 kg/m³ for CP2, indicating potential structural strength.
Water absorption rates are 10.1% for CP1 and 7.3% for CP2, suggesting enhanced durability characteristics.
Bricks were produced using cement and mining waste with fly ash/bottom ash blends tested under TCVN 6477:2016 standards.
The study highlights the utilization of mining waste, pointing to environmental benefits in brick production.

Hung Thang Hoang (2025) studied this question.
