Abstract:
This CD-ROM consists of 14 papers that were presented at ACI conventions in Charlotte, NC,and Denver, CO, in 2006. Selected examples of FRC applications highlighted in this special publication include slab-on-ground, jointless slabs, thin section composites, prefabricated modular housing elements, concrete buried structures, concrete infrastructure repair, fire-resistant concrete, decorative concrete, and shotcrete.

Glass fiber-reinforced Concrete (GFRC) has now been in use worldwide for over 30 years. There are many varied applications for this composite material and this paper describes four specific applications that illustrate the benefits that GFRC offers to the construction industry.

The common problems associated with concrete include drying shrinkage, cracking and curling. This paper will discuss how two time proven technologies, namely, Type K shrinkage-compensating concrete and synthetic fibers, have been combined to eliminate, or at the very least minimize, these problems. In the absence of drying shrinkage, concrete does not develop drying shrinkage cracks, control joints become unnecessary, curling is almost non-existent, spalling at joints is minimized since the only joints required are the construction joints, and required ongoing maintenance of the slab is minimal since there are so few joints. The Type K shrinkage-compensating concrete addresses the problem of concrete shrinkage and the synthetic fibers restrain the expansion of the Type K shrinkage-compensating concrete. Temperature steel for crack control can be eliminated and both the initial costs and the life-cycle costs are normally lowered. The combination of Type K shrinkage-compensating concrete and synthetic fibers has created a new future for concrete.

The current research shows that the addition of steel fibers to plain concrete is effective in enhancing the tensile ductility and loading capacity of buried concrete structures such as bridges, culverts, and vaults. This paper details the development of a steel fiber reinforced concrete (SFRC) analytical model used in the finite element program, CANDE, and describes the experimental and analytical approach used to test the accuracy of the model. The results of full-scale, in-place load tests on many precast buried SFRC arch structures (composed of less than or equal to 1% steel fibers by volume) correlated well with the CANDE model predictions. The CANDE program exhibits the ability to model the material behavior of SFRC as well as the effects of soil-structure interaction. The analytical and experimental research summarized in this paper leads to the ability to design SFRC for structural applications such as buried bridges, culverts, and vaults.

The structural use of steel fibers as the only principal reinforcing has been developed and refined for the last 15 years. Total replacement of traditional rebar is now common in applications like suspended slabs resting on a pile grid which spans from 3 m (10 ft) to 5 m (17 ft) each way. Generally, the span-depth ratio of the slabs in such applications ranges from 12 to 25. Although most of these slabs use the ground as a form only, some of them have been cast in elevated conditions without any contact with the ground to ensure total independence in the event expansive clay or gas hazards are present or could be present. More recently, steel fiber reinforced concrete has been used in suspended elevated slabs with a span-depth ratio equal to 30, and spans from 5 to 8 m (17 to 26 ft) length. The present article reviews the concrete mix design, the type of steel fiber, the dosage rate needed, the hardened concrete testing method based on current standard documents and round indeterminate panel slab tests. An example of steel fiber-reinforced concrete elevated slab is given and the design method is outlined in detail.
