Table 4.2.2: TB-113 Results for Mix M2 (A1+E2)
Parts by dry weight of aggregate, g
Formulation agg, g cement water additive* emulsion
Based on the data contained in Table 4.2.2, the mixture components selected for the AMT for
Mix M2 were as follows:
• 100 grams of aggregate
• 1.5 grams of cement
• 8 grams of water (Based on the weight of dry aggregate)
• 13 grams of emulsion
• 0.25 grams of additive
The resulting mix had the following characteristics:
• Very stable and displayed a wide range of compositions
• Very quick set
• Proceeded to clear water and exhibited cohesive form
In addition to the “base mixture” noted above for M2, components were varied to produce
mixtures with the following consistencies for further testing:
• Soupy

Consistency Blot Test
S = Soupy (Brown free liquid, segregating sample) A = Aggregate and clear water
LV = Low Viscosity (Non segregating easy to mix) BT= Brown transfer
MV = Moderate Viscosity (Non segregating, moderate resistance to mix) CW= clear water
St = Stiff (Hard to mix but workable)
B = Broken (Lumps, non consistent)
