Mix design concrete procedure has two objectives. One to achieve the minimum required strength and two to prepare the concrete in the most economical manner. Cost-wise, all concrete depends primarily on two factors, namely the cost of labor and the cost of material. Labor cost includes form-work, batching, mixing, trans porting, and curing, with slight variations between good bad quality concrete.
