Cement mix design is often mistakenly referred to as "concrete mix design." However, cement is simply one of the ingredients of concrete. It is a binding substance that allows concrete to set, harden, and adhere to other materials. Therefore, it cannot and should not be used interchangeably with concrete mix design. Calculating Concrete …
More DetailsThese concrete mix ratios for 3000, 3500, 4000, and 4500 psi concrete come from the ready mix concrete company I use to pour concrete floors, slabs, patios, pool decks, and stamped concrete. I'm going to show you the actual batch plant ticket they give me when the concrete trucks show up on the job and we pour the concrete. My name is Mike Day.
