• Abstract:

  The wide-spread use of concrete in the construction of roads, pavements and floors is one of the notable features of recent developments in this field.During the past six years the Structural Materials Research Laboratory, Lewis Institute, Chicago, has carried out eleven different series of tests on the wear of concrete as affected by the following factors:
  1. Method of conducting the test;
  2. Quantity of water;
  3. Quantity of cement;
  4. Grading of aggregate;
  5. Grading of coarse aggregate;
  6. Comparison of different fine aggregates;
  7. Comparison of different coarse aggregates;
  8. Hydrated lime and other powdered admixtures;
  9. Relation of compressive strength to wear;
  10. Age of concrete;
  11. Time of mixing concrete;
  12. Curing condition of concrete.
  Wear tests were made in the Talbot-Jones rattler. The history of the development of the present wear tests and a brief bibliography were given in earlier papers. These investigations include tests of about 10,000 wear blocks and probably as many compression tests of concrete cylinders. The wear was measured by the thickness of concrete removed during the test; a low wear corresponds to a high resistance to wear.
