May 30, 2018· The concrete mix design involves various steps, calculations and laboratory testing to find right mix proportions. This process is usually adopted for structures which requires higher grades of concrete such as M25 and above and large construction projects where quantity of concrete consumption is huge.
American Concrete has been delivering readymix concrete in Parker, Tarrant, and surrounding counties for over 20 years. With one of the largest mixer fleets in Texas, we are ready to provide you with outstanding service on your next project.
