Mechanical and Microstructural Characterization of Rammed Earth Stabilized with Five Biopolymers

Alessia Emanuela Losini et al.

Summary: This study investigates the compatibility of different waste and recycled biopolymers for rammed earth applications and finds that three biopolymers are suitable as stabilizers. Sheep wool increases the compressive strength, while lignin sulfonate and tannin fill pores, coat soil grains and form aggregates.

Fracture toughness characterisation of a glass fibre-reinforced plastic composite

Sabrina Vantadori et al.

Summary: This research focused on the fracture behavior of plastic composites reinforced with continuous glass fibers. The modified two-parameter model (MTPM) was used to analyze the fracture toughness of unidirectional glass fiber-reinforced plastic (GFRP), with input data obtained from experimental three-point bending tests on edge-notched specimens of different sizes.

Fracture behaviour of hybrid fibre-reinforced roller-compacted concrete used in pavements

Daniela Scorza et al.

Summary: This study aims to investigate the fracture properties of hybrid fibre-reinforced Roller-Compacted Concretes (RCCs) used in pavements, conducting tests on both single and hybrid fibre-reinforced concrete specimens and utilizing a Modified Two Parameter Model to calculate mixed-mode fracture toughness. Ductility is evaluated through a toughness index, while the impact of reinforcing fibres on post-peak material behavior is also discussed.

Characterization of the mechanical and physical properties of unstabilized rammed earth: A review

Fernando Avila et al.

Summary: The construction sector is increasingly focusing on sustainable development, using locally available materials like rammed earth to reduce environmental impact. Research shows that compressive strength is the most representative parameter for rammed earth, while tensile and shear strength are low and require further investigation.

Alternative stabilised rammed earth materials incorporating recycled waste and industrial by-products: A study of mechanical properties, flexure and bond strength

Alexandra H. Meek et al.

Summary: Developing low-embodied energy building materials is crucial for reducing global greenhouse gas emissions, but proper understanding and testing are necessary before industry adoption. This study extends the knowledge of rammed earth materials through mechanical testing of reinforced specimens and evaluation of existing testing standards. Results showed that current procedures for concrete specimens are suitable for estimating certain mechanical properties of rammed earth materials.
