Non-structural concrete floor slab e.g. for industrial use includes metal reinforcing mesh layer close to surface to control shrinkage during drying and hardening

摘要

#CMT# #/CMT# The non-structural floor slab (1) is laid on top of a finished supporting surface (2) and an interface layer (3). It comprises a poured concrete matrix with metal fibres, has an insert (4), especially of reinforcing mesh (5) included close to its surface to control shrinkage of the concrete as it dries and hardens. The reinforcing mesh is made from rods of at least 2.57 cm in cross-section, held up by supports (6), and is covered with at least 25 mm of concrete. #CMT#USE : #/CMT# Floor slab for industrial building subject to heavy traffic such as forklift trucks. #CMT#ADVANTAGE : #/CMT# Increased mechanical strength and reduced risk of shrinkage and cracking. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show a cross-section and overhead views of parts of the floor. 1 : Concrete slab 2 : Supporting surface 3 : Interface layer 4 : Insert 5 : Reinforcing mesh 6 : Supports 17 : Additional reinforcement #CMT#POLYMERS : #/CMT# The interface layer is preferably of polyethylene film.
