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 201.6
• 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)
