Why is concrete mix design needed?
A good concrete mix design creates the foundation of a sound infrastructure. Concrete mix design involves a process of preparation in which a mix of ingredients creates the required strength and durability for the concrete structure. This will ensure the structure will be sound and prevent failure of the mix.
