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

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

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

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

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

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

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