Table 2 Mortar mix design for 1 m3 and flow, void ratio and shrinkage properties.

From: Tensile Performance, Lap-Splice Length and Behavior of Concretes Confined by Prefabricated C-FRCM System

Mortar C (kg) SF (kg) WGP (kg) Sand (kg) W (kg) w/b Flow (cm) Void ratio (%) εsh,90d (μm/m)
HM-RFA 550 27.5 110 1487 206 0.3 24.2 17.6 694
HM-NFA 530 26.5 106 1573 190 0.3 22.5
  1. C: cement; SF: silica fume; WGP: waste glass powder; RFA: recycled fine aggregate (≤ 2.5 mm); NFA: natural fine aggregate (≤ 2.5 mm); polycarboxylate superplasticizer 1% and 2% of binder by mass for HM-RFA and HM-NFA, respectively; small amount of defoaming agent is used; Mortar flow was determined following KS L 5105; Void ratio was determined following ASTM D642; εsh,90d: total shrinkage after 90 days.
