1、Designation: D 6024 07Standard Test Method forBall Drop on Controlled Low Strength Material (CLSM) toDetermine Suitability for Load Application1This standard is issued under the fixed designation D 6024; the number immediately following the designation indicates the year oforiginal adoption or, in t
2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This test method explains the determination of theability of Controlled Low Strengt

4、ulated, or recorded in this test method is not directly relatedto the accuracy to which the data can be applied in design orother uses, or both. How one applies the results obtained usingthis standard is beyond its scope.1.3 The values stated in SI units are to be regarded as thestandard. The inch-p

11、fill, CLSM can be placed as a slurry, a mortar, or acompacted material and typically has strengths of 350 to 700kPa (50 to 100 psi) for most applications.4. Summary of Test Method4.1 Astandard cylindrical weight is dropped five times froma specific height onto the surface of in-place CLSM. Thediamet
12、er of the resulting indentation is measured and comparedto established criteria. The indentation is inspected for any freewater brought to the surface from the impact.5. Significance and Use5.1 This test method is used primarily as a field test todetermine the readiness of the CLSM to accept loads p
