Effect of polypropylene fibers on the shear strength–dilation behavior of compacted lateritic soils
(2021-11-01)
The stress–dilatancy relationship for fiber-reinforced soils has been the focus of recent studies. This relationship can be used as a foundation for the development of constitutive models for fiber-reinforced soils. The ...
Shear strength behavior of clayey soil reinforced with polypropylene fibers under drained and undrained conditions
(2021-01-01)
The fundamental mechanisms controlling shear strength and deformability behavior of clay-fiber mixtures have still not been well established, nor the constraints that may affect their performance of shearing under different ...
Avaliação da influência de fibras de polipropileno na resistência efetiva de um solo argiloso
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2019-06-28)
The use of soil-fiber has been recognized as a viable technique of soil improvement in numerous geotechnical applications. However, existing research has not yet established the fundamental mechanisms controlling the ...
Solo siltoso da formação Guabirotuba reforçado com fibras de polipropileno
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia de CivilUTFPR, 2020-01-28)
Several studies have sought to improve the mechanical behavior of soils, with the use of synthetic or natural additives, for use in civil engineering works. In this context, research with the use of polypropylene fibers ...
Improvement of the shear strength parameters of an expansive soil using recycled glass powder and polypropylene fibers
(Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
n this article, the geotechnical behavior of the reinforced soil is studied through additions of polypropylene fiber and recycled glass powder, this in order to obtain a homogeneously reinforced soil matrix to reduce ...
Comportamento mecânico de um solo reforçado com fibra de Curauá (Ananas erectifolius)
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia CivilUTFPR, 2020-04-17)
The application of reinforcement with fibers in soils has been introduced with the purpose to provide this material with improvement in its reforms in soils arose with the use of mechanical properties, especially in shear ...
Fabrication of Pineapple Leaf Fibers Reinforced Composites
(2020-01-01)
Consumers are more aware of environmental impacts and climatic problems, which leads to a greater demand for products with technological innovations. Research has the aim to replace and reduce raw materials from fossil ...
Modeling the fiber addition influence on the small strain shear modulus of sand
(Springer, 2017-07)
The mechanical behavior of fiber reinforced soils has been extensively studied in the last decades. Previous studies have shown that inclusion of fibers increases the shear strength of the reinforced soil. However, the ...
Sisal chemically modified with lignins: Correlation between fibers and phenolic composites properties
(ELSEVIER SCI LTD, 2008)
Sisal fibers have been chemically modified by reaction with lignins, extracted from sugarcane bagasse and Pinus-type wood and then hydroxymethylated, to increase adhesion in resol-type phenolic thermoset matrices. Inverse ...
