21. But pozzolanic reacted cement has lower compressive strength at 15 MPa maximum. 22. While compared to its compressive strength, concrete is weak in tension. 23. Modern processes are highly controlled and include a compressive force on the billet. 24. The resulting conoids, however, require great compressive forces to keep shape. 25. Compressive forces built up along the entire length of the broad continental shelf.26. Metal whiskers form in the presence of compressive stress. 27. Compressive protection may be provided by inexpensive earth arching.28. The greater the tensile cold working, the lower the compressive yield strength. 29. Hip hiking places excessive side-bending compressive stresses on the lumbar segments. 30. Aggrecan provides intervertebral disc and cartilage with the ability to resist compressive loads.
