  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)

  8. RESOURCES • ACI 229R “Controlled Low-Strength Materials” Report • NRMCA
