Step 2 Add the dry mix into the mixer and allow the mortar to mix for about a minute, then add the remaining water as necessary. Step 3 Continue to mix for 3-5 minutes, until a uniform, workable consistency is achieved. Step 4

Learn MoreYou will require cement, sand, gravel, and water for making the concrete mix. Put the cement, sand, and gravel in the container at a ratio of 1:2:3. Start mixing water in the container and stir the mixture continuously with a rod. Pour water until the concrete mixture become pliable enough to pour in the mold.

Learn MoreMortar mix ratio i.e. proportioning of cement sand in mortar provides consistency in the performance and appearance of masonry construction. Proper proportioning of mortar ingredients helps in having the following advantages: Uniformity of strength Uniform workability Uniform color Uniformity of proportions and yields Mainly the proportioning of the cement and sand for mortar are conducted […]

Learn MoreSep 26, 2017 · If you are doing some do-it-yourself work with concrete blocks, that may require you to mix your own mortar. While it may sound simple, it can be much more difficult than you can imagine. Mortar that is mixed incorrectly may not hold the blocks in place. It could crack, break or cause the constructed item to be unsteady and insecure.
