Material Mix Design for Masonry Grouting - Masonry Magazine

Contractors who use buckets and/or grout scoops have little to no restriction on what type of mix design can be used. The only limit to grouting by buckets is the available labor. If using a material delivery system or a grout pump, contractors can use masonry grouts prepared according to C476 in most cases.
