It is virtually impossible to specify the proportion of water in a concrete mix due to the wide range of moisture content in the sand used, Regarding "old" cement powder if kept completely and utterly dry it will work fine after literally years. The only downside of using old cement is that the Chromium additives change from relatively harmless to relatively harmful. In my opinion if proper ...

 · The results show that the manufactured sand concrete made in this study generally requires a higher water/cement (w/c) ratio for workability equal to that of natural sand concrete due to the higher angularity of the manufactured sand particles. Water reducing admixtures can be used to compensate for this if the manufactured sand does not contain clay particles. At the same w/c ratio, .

 · In other words, a concrete mix ratio allows you to reliably add the right amounts of powdered cement, aggregate, and sand when mixing the same type of concrete. A concrete mix ratio is usually expressed by a set of numbers separated by colons, as is the case with a 1:2:3 ratio. This tells the mixer that they need to add 1 part cement powder, 2 parts sand, and 3 parts aggregate in order to ...

 · Manufactured sands tend to be used in mixtures in areas where natural sand is not available or not cost effective to be hauled to the needed loion. MFA tends to be more angular and flaky due to the crushing process. Highly angular particles tend to increase the paste content of concrete because additional lubriion is required for particles with sharp corners.

The Ideal Cement and Sand Ratio for Wall Plastering ...

The sand to cement mix ratio is described with help of variety of appliions, take a look: If you want to plaster with concrete mix then take 1 part cement and 2 part concreting sand. Whereas if you plan to use mortar mix for walls, then the ideal cement mortar ratio for plastering would consist 1 part cement and 4 to 5 parts of building sand.
