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)
