A fire resistance rating is based on a fire resistance period and usually given in half-hour or hourly increments. As an example, a wall with a fire resistance period of 2 hours and 25 minutes may only attain a fire resistance rating of 2 hours. It is also referred to as a fire rating, fire resistance classification or hourly rating.

Speedfloor slabs offer fire rating of up to 180 mins without the need to install a fire rated ceiling or any other proprietary product to be installed. The Speedfloor concrete floor system also offers excellent acoustic performance without any special requirements.

Concrete cover plays an important role in reducing the temperature of the steel and thus maintaining steel strength and member strength for a given fire resistance. The ACI Fire Code includes Tables stating the (1) minimum concrete cover for reinforcement in concrete floors and roof slabs, (2) minimum concrete cover for nonprestressed and ... A firestop or fire-stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestops are designed to maintain the fireproofing of a wall or floor assembly allowing it to impede the spread of fire and smoke.

This table is based on the CRSI reinforced concrete fire resistance manual. This guide pretty much excludes me from using the 4.5" slab as a 2 hour rating by itself. Does anyone know of a UL listing of floor slab thicknesses/fire ratings. Or what fire proofing would be required to supplement the concrete flooor?concrete is offset by size reduction of structural elements, less reinforcing steel and reduced volume of concrete, resulting in lower overall cost. In buildings, structural lightweight concrete provides a higher fire-rated concrete structure. Structural lightweight concrete also benefits from energy conservation on the fire performance of concrete slabs in standard and natural fires. The results were compared with published test data and finite element software simulations to benchmark the accuracy of the proposed tool. Furthermore, methods for the design of reinforced concrete slabs in fire conditions are presented.Slab with siliceous aggregate and 3/4" minimum cover requires 5" thickness (oops not 4.5"...sorry) to achieve 2 hour rating.

Results for both are compared at each of 21 frequencies and a change (or delta) is calculated. Can provide an estimate of the IIC rating for a specific Concrete is not generally thought of as "fireproof" because the intense heat of a fire can cause chemical reactions to take place in the concrete that weaken it. That said, there are refractory mortars that are useful for bonding chimney bricks together and they can be considered "fireproof". Firefighters must be familiar enough with penetrations of fire-rated walls and floor-ceiling assemblies that they can recognize one that may be deficient, Greg Havel writes. The building code (2003 IBC) has this to say: "1906.3 Conduits and pipes embedded in concrete. Conduits, pipes and sleeves of any material not harmful to concrete and within the limitations of ACI 318, Section 6.3, are permitted to be embedded in concrete with approval of the registered design professional." .

Floor slab UNBRACED HEIGHT OR LENGTH OF CONCRETE WALLS The use of pilasters should be avoided. Where required, they should be regularly spaced and of consistent, standard dimensions. 108 FIRE-RESISTANCE RATINGS FOR SITECAST CONCRETE WALLS Fire-resistance ratings for concrete construction vary with the type and density of concrete used.
