- This test method is designed to determine the resistance to bleeding of freshly-mixed cementitious grout under static pressure. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. This test method does not purport to address all of the safety issues@ if any@ associated with its use. It is the responsibility of the user of this test method to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before use. (Warning??Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.*) *Section on Safety Precautions@ Manual of Aggregate and Concrete Testing@ Annual Book of ASTM Standards@ V. 04.02.

钢筋预应力测定仪使用方法
2、张拉（1）同时张拉多根预应力筋时，应预先调整其初应力，使相互之间的应力一致；张拉过程中，应使活动横梁与固定横梁始终保持平行，并应抽查力筋的预应力值，其偏差的值不得超过按一个构件全部力筋预应力总值的5%。（2）预应力筋张拉完毕后，与设计位置的偏差不得大于5mm，同时不得大于构件最短边长的4%。（3）预应力筋的张拉应符合设计要求，设计无规定时，其张拉程序可按先张法预应力筋张拉程序的规定进行。...
