fib COM6 prefabrication
COM6 Background
Prefabrication plays an important role in structural concrete construction worldwideand is evolving continuously, to cope with current society’s habits and needs related to housing, commercial buildings and civil engineering works.
Industrialized construction brings cost efficiency, good quality and environmentally friendly solutions, able to adapt to market demands.
COM6 Goal
The basic goal of the Commission Prefabrication is to enhance the progress of precast concrete, linked to the state of art.
The general scope is to promote the understanding, not only by the specialists, ofdesign concepts, technology and use of precast concrete.

Hollow Core1. Prestressed slabs varying in thickness from 4 to 12 inches having hollow interior cores to reduce weight, generally extruded.
2. is a precast slab of (prestressed) concrete typically used in the construction of floors in multi-story apartment buildings. The precast concrete slab has tubular voids extending the full length of the slab. This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. The slabs are typically 120 cm wide with standard thicknesses between 15 cm and 50 cm.
