This paper discusses the use of alkali resistant cellulose fibers for decorative applications. The penetration of fibrous reinforcement for decorative concrete applications has been somewhat limited. The main barrier has been interference of the fiber during many of the intricate and complicated finishing steps employed in these high-end concrete applications. Some of the complications encountered are fibers sticking to the stamps and dragging out of the surface, fiber clumps found at the surface creating blemishes, lack of stain receptivity by the fibers, etc. These aesthetic complications can often result in customer dissatisfaction with the final product. The commercial entry of alkali resistant cellulose fibers for fibrous reinforcement in concrete has provided a new option for fiber reinforced concrete in decorative concrete applications. The potential benefits of cellulose fibers in concrete are expected to help further enlarge the use of fiber reinforced concrete in the market place.

This paper discusses the recent tragedies of a number of tunnel fires occurring in transport tunnels, and the effects of these fires on concrete tunnel support linings. The mechanisms of explosive spalling of concrete in fires is described, and the research conducted to assess the ability of fine, polypropylene fibers to mitigate the effects of explosive spalling in severe fires is described. The test program to assess the fire resistance of the 25 miles (40 km) of concrete-lined tunnels in the Channel Tunnel Rail Link project in the United Kingdom is described in detail. A program to ascertain the effects of using these fibers in shotcrete tunnel linings is also considered. These programs demonstrate that small quantities – as little as 1.7 lb/yd3 (1 kg/m3) – of mono-filament polypropylene fibers provide resistance to explosive spalling in fires. Examples of the application of this new technology are listed.

Prefabricated modular housing structures have become a promising alternative to site-built structures with equal or higher engineering quality and durability. Major advantages of this technology are fast and cost-efficient construction, reduced labor requirements, and superior quality control due to factory production. The modular design of these prefabricated structures offers the opportunity for research and application of innovative composite materials and structural concepts. Engineered Cementitious Composites (ECC) in combination with light gauge steel joists and steel trusses have been utilized in the development of modular floor panels for prefabrication of housing structures. The need for steel reinforcement in conventional reinforced concrete thin shell construction creates a technological difficulty as the placement of the reinforcing steel is very labor intensive and proper positioning of the reinforcing mats is difficult. The use of fiber reinforced Engineered Cementitious Composites (ECC) helped eliminate these constraints and lead to more efficient prefabricated structural elements.
