Fibre reinforced concrete for the agricultural sector
Barn floors, yard pavements and manure pits: chemical loading, heavy use and permanent moisture. Synthetic and basalt fibre are corrosion-free here.
Agricultural floors — from barn floors to yard pavements and manure pits — place unique demands on concrete: chemical exposure from manure, intensive use by heavy livestock and agricultural machinery, and often a permanently damp environment. Fibre reinforcement fits well here. This article discusses the applications and benefits.
The specific loads on agricultural floors
Barn floors and yard pavements in agriculture face a combination of loads that few other applications encounter:
• Chemical exposure from manure, which contains ammonia and acids that can attack traditional reinforcing steel once the concrete cover is damaged.
• Heavy, concentrated loading from livestock and heavy agricultural machinery such as tractors, manure spreaders and cattle trailers.
• Permanent moisture exposure, which increases the risk of corrosion of traditional reinforcement.
• Temperature fluctuations, from frost to heat, depending on the season.
Why fibre reinforcement fits well here
• No corrosion risk under chemical exposure. Synthetic and basalt fibres are chemically inert and therefore unaffected by the corrosive action of manure acids on reinforcement — a risk that is genuinely present with traditional steel reinforcement once the concrete cover is damaged.
• Resistant to intensive, concentrated loading. Fibres distribute point loads (for example from livestock hooves or the wheels of heavy machinery) more evenly across the concrete, which slows cracking and spalling.
• Suitable for large, flat surfaces. Barn floors and yard pavements often cover large areas, where eliminating a separate reinforcement work step delivers a considerable saving in time and cost.
Specific applications
• Barn floors: where chemical resistance and wear resistance against hoof loading are key. Basalt fibre is specifically noted here as a suitable application because of its combination of chemical resistance and strength.
• Yard pavements and access roads: driven on intensively by heavy agricultural vehicles.
• Manure pits and silos: where chemical resistance to manure is a primary requirement.
• Silage slabs: large, flat surfaces with heavy point loading from vehicles.
Points of attention
For primarily structural elements — for example load-bearing floors above manure pits — it remains prudent to have the reinforcement choice calculated by a structural engineer, even when fibre reinforcement is being considered. For non-structural applications such as yard pavements, fibre reinforcement is often directly applicable.
In conclusion
The combination of chemical exposure, intensive use and moisture makes agricultural floors a prime application for fibre reinforced concrete, particularly with synthetic or basalt fibre because of the absence of corrosion risk.
