Design Guide for Ferrocement
|Publication Date:||1 September 2018|
This guide is based on technical information assembled from current practice, developments, and advances in the field of ferrocement around the world. It represents a practical supplement to ACI 549R. This guide covers physical and mechanical properties, performance and design criteria, and testing
The objectives of this guide, in conjunction with ACI 549R, are to promote the effective use of ferrocement in structures, provide architects and engineers with the necessary tools to specify and use ferrocement, and provide owners or their representatives with a reference document to check the acceptability of a ferrocement alternative in a given application. This guide is consistent with ACI 318, except for the special characteristics of ferrocement, such as reinforcement cover and limits on deflection
Ferrocement is a form of reinforced concrete using closely spaced multiple layers of mesh, small-diameter rods completely infiltrated with mortar, or encapsulated in mortar, or both. The most common type of reinforcement is steel mesh. Other materials such as selected organic, natural, or synthetic fibers may be combined with metallic mesh. This guide addresses only the use of steel reinforcement in a hydraulic cement mortar matrix.
Applications of ferrocement are numerous, especially in structures or structural components where self-help or low levels of skills are required. Besides boats and marine structures, ferrocement is also used for housing units, water tanks, grain silos, flat or corrugated roofing sheets, and irrigation channels (ACI 549R).
