How to MIX CONCRETE for the home builder - cement mixer or have it delivered?

How do we choose between ready mixed or hand mix concrete for our home extension projects, and how do we even quantify the mix? For a link to the concrete mix spreadsheet I show in the video, see my other video here: Cement, Sand & Aggregate Concrete mix explained - DIY Spreadsheet https://youtu.be/83ZzGLx1JCc In a previous video we talked about the foundation design and how you could do a lot of that yourself, as well as how to accurately and easily quantify your foundation concrete quantity https://youtu.be/9v7En8gIRoE Then we went through the preparation and setting out, how to dig the trenches and what equipment and tools, the costs and time involved for doing it yourself. https://youtu.be/CpMPwhV_BE4 Here I’ll show you how to order the right amount of materials, and what else you need in order to be fully prepared and budgeted for building your own foundations and footings . I compare the costs of hand mixing for a small home extension foundation, versus the ready mix method where the lorry or truck arrives with the concrete premixed. I describe how to get the right mix of aggregate, sand and cement for the strength of concrete you require, and then we go through the costs of each solution. I will shortly put up a link to another video showing my spreadsheet for automating this process and which I touch upon here in this video.
