      1. Hello Krunal,

        You mentioned that “the four-two-one mix, obviously, has seven parts”. Cement, aggravate/sand, gravel, water, and what else? Please provide the remaining three parts.

        Thank you,
        Frank

  1. M30 Grade Concrete Need Ratio And Minimum Or Maximum Passing 10mm Chips And 20mm Aggregate What is The Shape 20mm aggregate 1st good quality Material.

  2. Nice job explaining the different ratios. Not alot of actual ratios on the web im glad i found your website. Thanks

  3. You show a table for M-50 too 70-m but there are no numbers for the mix design.
    Can you please help?
    Thank you.

  4. SAMPLE RATIO: 1:2:4
    1 = ONE BAG OF CEMENT = 40 LBS/BAG
    2 = TWO BOXES OF SAND
    4 = FOUR BOXES OF AGGREGATES
    MY QUESTION ; WHAT IS THE MEASUREMENT OF ONE BOX?

  5. Great information. How much more strength with fibers (guess depends on quantiy, size and length) which have good air resistance (for aircrete). Thank you very much in advance for expected your valuable help.

  6. I was searching for a concrete mixer. Thanks, admin, for sharing such wonderful content on this topic. Now I have got everything I need about it. Here’s another informative piece of content Concrete Mixer , you may find here more information.

  7. RATIO
    1;4;8 FOR 7MPA

    1X 50KG CEMENT
    4 X WHEEL BARROWS OF SAND
    8 X WHEEL BARROWS OF CRUSHER DUST
    CAN THIS BE USED TO MAKE CONCRETE BLOCKS

    1. No, there will not be two different mix ratios for the same grade of concrete. The mix ratio for a particular grade of concrete is determined based on the required strength and workability of the concrete, and it should be consistent for all batches of that grade of concrete.

      For example, if you need to prepare M20 grade concrete, the mix ratio would be determined based on the required compressive strength and workability of the concrete, and the same mix ratio would be used for all batches of M20 grade concrete.

      However, it’s worth noting that there may be different types of mix designs for the same grade of concrete, depending on factors such as the source and type of materials used, the local climate, and other environmental conditions. These different mix designs may result in slightly different mix ratios, but they should all meet the requirements for the specified grade of concrete.

      I hope this helps clarify your question. Let me know if you have any further questions or if there is anything else I can assist you with.
