Figure 4.25: Comparison of Losses as Determined by Wet and Dry Loss Methods Aggregate and Emulsion Effects The Aluminum base support was used and the tests repeated with two mixes, Mix M2a and Mix M2b. These mixes were cured at 77°F (25°C) and 70% humidity. The mix proportions were as follows: Mix M2a Mix M2b Loss (g) 400 350 300 250 200 150 100 50 0 • 100 grams of aggregate • 1 gram of cement • 9 grams of water (Based on the weight of dry aggregate) • 0.5 gram of additive • 15 grams of emulsion • 100 grams of aggregate • 0.5 gram of cement • 10 grams of water (Based on the weight of dry aggregate) • 0.5 gram of additive • 15 grams of emulsion Wet Loss Vs. Dry Loss method 30 60 180 Time of Cure (Min) 77°F (25°C ) 70% humidity. 63 Wet loss Felt Wet loss Steel Wet loss Al Dry loss Felt Dry Loss Steel Dry loss Al
The differences in the samples were the amount of water and cement. Test results are summarized in Table 4.8. The decrease in loss with time is shown in Figures 4.26 and 4.27. ` Table 4.8: CAT Results for Mix M2a and M2b Mix Pre-treat Compaction Time of cure (min) Loss wet (g) Loss Oven dry (g) % A N 30 265/250 26.1 N 60 165/170 12.6 N 180 77/72 6.4 A Y 30 - - Y 60 145/155 - Y 180 - - B N 30 433.9/455 28.8 N 60 275/285 19.2 N 180 239.5/225 15.9 B Y 30 - Dry Loss % 35 30 25 20 15 10 5 0 Y 60 220 - Y 180 - Effect of Water Level on Cure (Dry Loss) 30 60 180 Time of Cure (Min) 70°F (25°C) 70% Humidity Figure 4.26: Effect of Water Level on Cure M2 Mixes (Dry Loss Method) 64 Mix M2a Mix M2b
