Polymer-Modified Mortars And Concrete Mix Design

2019-2-4  The mix proportions of most latex-modified concretes can not be easily determined in the same manner as those of latex-modified mortars, because of many factors are to be considered in the mix design. Normally the polymer-cement ratio of the latex-modified concrete ranges from 5 to 15%, and the water-cement ratio from 30 to 50%. A rational mix

Can you mix mortar and concrete together? - TreeHozz

2020-2-20  1 Answer. Mortar is similar to concrete in that they both contain Portland cement and sand. The 2 different ingredients are that mortar has hydrated lime and concrete has larger aggregates (stones). The added Portland cement and sand may produce a strong enough mix, but the mortars' hydrated lime is the weak link.
