Common heavy aggregates used in protective concrete in Nepal include:
Crushed gravel: This is the most widely used aggregate for concrete in Nepal. It is produced by crushing larger stones into smaller, angular pieces. Crushed gravel provides good strength and durability for protective concrete.
Granite: Granite is a strong, igneous rock that is often used in high-performance concrete applications. It is available in Nepal and can be a good choice for protective concrete that needs to withstand extreme loads or harsh environments.
Basalt: Basalt is another strong, igneous rock that is commonly used as an aggregate. It is a good option for protective concrete that needs to be resistant to abrasion and wear.
