Decide whether these statements are true or false:

1. a). Glass fiber reinforced concrete composites contain high strength glass fibers that are used extensively for decorative panels.

b). Glass fiber reinforced concrete composites contain high strength glass fibers that are surrounded by a cementitious medium.

c). Glass fiber reinforced concrete composites contain high strength glass fibers that are consolidated in a matrix in the desired size.

2. a). The glass fibers are the main elements that carry the load, while the medium facilitates transfer of the load.

b). The glass fibers are the main elements that carry the load, although GFRC weighs only one-third of the original solid concrete weight.

c). The glass fibers are the main elements that carry the load, while the enclosed matrix keeps the fibers in the preferred position and direction.

3. a). Polymers may also be added in the glass fiber mixes in order to improve physical properties such as moisture movement.

b). Polymers may also be added in the glass fiber mixes in order to keep the fibers in the preferred position and direction.

c). Polymers may also be added in the glass fiber mixes in order to shield them from the damage due to environment.

4. a). The use of GFRC has become popular due to its adaptability for decorative concrete products.

b). The use of GFRC has become popular due to its natural chemical characteristics.

c). The use of GFRC has become popular due to its numerous favorable properties.

5. a). GFRC has been tested in the laboratory and also in the actual installations, and can be anticipated to be integrated into the matrix either in constant or irregular lengths.

b). GFRC has been tested in the laboratory and also in the actual installations, and can be anticipated to survive as long as pre-cast concrete.

c). GFRC has been tested in the laboratory and also in the actual installations, and can be anticipated to have improved resultant properties.
