#CMT# #/CMT# The slab (1) has a main face (6) edged by primary recesses (13, 14) associated to respective transversal wedge ribs (17, 18) extending in projection from the main face. The recesses comprise respective primary support faces (15, 16) that define a horizontal primary support plane (P1). The face (6) is merged with the plane and/or situated between the plane and a main face (7). The face (7) is edged by secondary recesses (23, 24) aligned vertically with the recesses (13, 14). The recesses (23, 24) comprise secondary support faces (25, 26) defining a secondary support plane. #CMT#USE : #/CMT# Absorptive form slab for being utilized as an absorptive form element for concrete that forms a floor of a building, and for being placed between precast joists to enclose a space separating the joists. #CMT#ADVANTAGE : #/CMT# The presence of two sets of the recesses permits to adopt two placement configurations for a same spacing of the pre-cast joists. The slab allows obtaining of two different thicknesses of compression table based on orientation of placement of the slab. The design of the slab permits to avoid concrete leakages at level of anchoring zones of the joists. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of an absorptive form slab.
