Testing Procedure for Determining the Bond-Slip Law of Steel Bars in Strain Hardening Cementitious CompositesBond-slipSteelPuEoutAnchorageIn order to advance the use of Strain Hardening Cementitious Composites (SHCC) in structural applications it is essential to understand the mechanics of bond of ...
Testing procedureThixotropyTimeWorkability lossRheological properties of cement-based materials are shear- and time dependent due to the chemical and physical particle bonding. Proper characterization of these properties is necessary to predict the behavior of concrete over time. Often, results on ...

The statistical tools such as descriptive statistics, full factorial design and analysis of source of variation were used to identify the potential factors that impact the validity of testing method for determining the strength of cement. The results showed that personal error impacted both accuracy an...
2 APPLICATION 2.1 All gravity tanks and other boundaries required to be watertight or weathertight are to be tested in accordance with this Procedure and proven tight and structurally adequate as follows: - Gravity Tanks for their tightness and structural adequacy, - Watertight Boundaries Other Than...
The current standard procedure for proppant characteristics evaluation still has a long way to go, as there are still many theories behind its mechanism that is not fully understood. The current procedure is limited to certain parameters. Although there have been some attempts to change the conducti...
The unit is designed for easy disassembly in order to replace worn or damaged parts in the field. The Super Pump is an important part of the Air Meter. It must be properly maintained to prevent air leakage. O-rings on the top of the pump and on the inside seal the unit. ...
