limestone could potentially be utilized in lower water-to-cement ratios less than 0.45 where a substantial fraction of the cement clinker particles remains un-hydrated effectively acting as a rather expensive filler material. Guemmadi and Resheidat et al. 2008 proposed optimal criteria of Algerian blended cement using limestone fines.

Calculate the amount of sand required to add to the mortar mix. Equal amounts of sand and mortar mix are combined with water when making mortar. Each bag of mortar mix weighs 100 pounds. Use the formula 100 pounds of sand for each bag of mortar mix. For example 36 bags of mortar mix will require 3600 pounds of sand.
