  • Is Quikrete As Good As Concrete | Premixed Vs Traditional

    For example, a concrete patio will usually set up and be walked on in a day, but it can take 28 days for the concrete to fully cure and reach maximum strength. quikretes ingredient ratios are a little different that regular concrete and they use a few secret additives they dont detail on the label.

  • Different Grades Of Concrete, Their Strength And Selection

    Grade of concrete is denoted by prefixing m to the desired strength in mpa. for example, for a grade of concrete with 20 mpa strength, it will be denoted by m20, where m stands for mix. these grade of concrete is converted into various mix proportions. for example, for m20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.
