Effect of Coarse Aggregate Size and Grouting Process on
Grout mix with desired flowability and strength was used to produce PAC by both pumping and gravity process. Four different sizes of coarse aggregates were considered i.e. 45mm, 37 mm, 20 mm and 14 mm. Variation in compressive strength against coarse aggregate size and grouting process was evaluated. Excess voidage and resistance to chloride ...

Grout vs. Concrete: Ultimate Strength Comparison
When the grout is used in bigger construction projects, builders may use a fine or a coarse grout, determined by the aggregate size used in the mixture. Coarse grouts are typically more economical to use for a big project. Epoxy grout can also be useful here because it tends to be stronger than cement-based grout.
