Concrete category
C8/10, C12/15 or
C16/20 X0 used in cases where
there is no risk of corrosion του οπλισμού ή χημικής προσβολής της μάζας του σκυροδέματος.
Το
X0 applies to
unreinforced concrete (without iron) and in structures located in
permanently dry environment, as no protection from moisture or chemicals is required. It is the basic choice for
cleaning concretes and fills, where the main role of the material is to fill space or create a flat surface rather than to bear large structural loads or resist environmental attack.
Where is it applied:
- Unreinforced Concrete: In structures that do not contain steel, such as clean concrete (foundation subgrade), floor fills and slope formations.
- Indoor spaces with very low humidity: In reinforced concrete elements located in a permanently dry environment (e.g. internal walls in residences), although in practice higher classes are selected for load-bearing elements.
- Small secondary structures: In curbs, pipe casings and garden decorative elements.
Exhibition Categories:
- C8/10 X0: It is applied exclusively in unreinforced structures and secondary works, with its main use as a cleaning concrete in foundations. Due to its low strength and lack of reinforcement, it does not require environmental protection (X0), functioning mainly as an auxiliary material for smoothing surfaces, filling floors or encasing pipes and curbs.
- C12/15 X0: It is applied exclusively in unreinforced structures and secondary works, with its main use as a cleaning concrete (gro-concrete) in foundations. Due to its low strength and lack of reinforcement, it does not require environmental protection (X0), functioning mainly as an auxiliary material for smoothing surfaces, filling floors or encasing pipes and curbs.
- C16/20 X0: It is applied in unreinforced concrete and auxiliary works, functioning mainly as a cleaning concrete or material for filling floors and slopes. Due to its low strength and the absence of reinforcement, it is classified in category X0, as it does not require protection from environmental factors, ensuring an economical solution for filling spaces and static support of secondary elements.
