Concrete sand is ideal for creating a stable base for structures that require durability and stability, such as pavements and retaining walls. Construction sand, on the other hand, is ideal for filling gaps and creating a smooth surface for structures that require a clean and even surface, such as bricklaying and plastering. Knowing the differences between concrete sand vs. construction sand and their uses can help you choose the right type of sand for your construction needs, ensuring a durable and stable structure.
