What are the most effective methods for constructing a durable and long-lasting concrete structure without the use of rocks?
One effective method for constructing a durable and long-lasting concrete structure without using rocks is to use alternative aggregates such as recycled materials like glass, plastic, or rubber. These materials can provide strength and durability to the concrete mix. Additionally, using high-quality cement and proper curing techniques can also help in creating a strong and long-lasting concrete structure.
