1. MAG – ARPA Meeting TESTING CLSM IN MAG 728 By R. TIXIER, Western Technologies

2. MAG SECTION 728 SAMPLING (D 4832, should be D 5971) CONSISTENCY TESTING – slump (C 143): effect of rodding ? – flow (D 6103): minus ¾ in. fraction, measure spread using 3” x 6” cylinder

3. MAG 728: COMPRESSIVE STRENGTH ASTM D 4832 – Typically, split 6 x 12 in. plastic cylindrical molds – No consolidation required – Transportation to laboratory at 4 days, may have to be delayed further Difficult to handle ½ - sack CLSM specimens

4. MAG 728: OTHER TESTS Temperature (C 1064) Unit weight (D 6023) Cement content (D 5982) Permeability, gas pipelines only (D 5048) Test Method for Measuring the Comparative Burning Characteristics and Resistance to Burn-Through of Solid Plastics Using 125- mm Flame More likely: D 5084

5. ARIZONA DOT, Section 501 “cement-treated slurry” Slump = 8 to 11 in. Cement content: 1 sack cement, 1 cu. yd. aggregates No strength testing?

6. “GREENBOOK”2006 Section 201.6 No consistency test Unit weight test per ASTM C138 Strength requirements, if any: on project plans

7. MISC. PROJECT SPECIFICATIONS Max. strength only Flow test Kelly ball (drop ball: D 6024)
