Various reinforcement methods based on the principal of concrete reinforcement were examined. After consideration of the requirements below, glass fiber was decided upon as the reinforcement material. 

Recently, new crystallisation methods for mesoporous amorphous oxides using combined assembly by the soft and hard (CASH) chemistry method and two-step wall reinforcing method have been reported. 

Firstly, engineering practice shows that the combinatorial controlling technique of reinforcement method (floor bolting) and pressure relief method (pressure-relief groove) has achieved remarkable...

The author has only been involved with two proof tests. One had a very large round flanged opening in a 2 1 SE head, offset from the vessel centerline, that resulted in significant loss of strucmral integrity of the head. Normal Code reinforcement methods were inadequate to replace the loss of rigidity of the head. 

We applied reinforcement method of anchor to rock failures of a large scale as in Figure 9. 

Because many reinforced methods for stabilization were appli and reinforced areas were wide, we painted the front view of the reinforcement methods in each segment as shown in Figure 10. 

Even metal structures may require an intervention of reinforcement due to changes in land uses, increases in loads, corrosion, or issues related to the phenomenon of fatigue. Currently, reinforcement methods used to restore the capacity of metal structures are based on the application of steel plates to the original structure. These types of interventions have negative aspects, such as new loads on the structures and oxidation phenomena. 

In parallel with these developments there has been a more effective method of measurement of reinforcement. Methods currently used to determine this require the filler to be comminuted by means of ultrasound, but this causes severe degradation of the agglomerates in carbon blacks, and also distorts the distribution of silicas. An alternative method has been developed using transmission electronic microscopy, in which the filler morphology retained is similar to that obtained in the incorporation process. As well as improvement of mixing and processing of filler-reinforced compounds today, the researchers believe it will be possible in future to use the AIBN procedure to develop new fillers more selectively. 

Many other polymer properties, such as stress, compressive set, strain, shear strength, friction coefficient, shrinkage, toughness, abrasion resistance, stress relation compressive creep, weatherability, and resistance to various types of radiation, can be of importance in polymers, whether or not they are reinforced. Methods for measuring these properties are discussed in Chapter 2. 

One of the main disadvantages of this reinforcement method is that it gives no information on stresses and these can vary significantly from one design to another resulting in differing performances, especially for cyclic loadings. 

More investigation conducted with a control group to measure external performance criteria such as reduction in near miss incidents and in reinforcement methods to ensure greater effectiveness and sustainability seems warranted for the process. 

The mechanical strength of concrete may be improved by reinforcement methods (e.g., embedment into the fresh concrete of steel rods, wires).
