Adding Lime to Concrete DoItYourself

Some experienced builders, however, will use a 1:1:4 ratio instead—one part lime, one part cement, and four parts sand. Lime can also be used simply as an additive in other concrete mixes, as well as cement mortars. For mortars, this process can take time, as quicklime has to be mixed with water to create a putty which
