Influence of Matrix and the Fibre Orientation on the Mechanical Performance and Slope Protection of Three Dimensional Geosynthetic Cementitious Composite Mats

Abstract

Slope protection is necessary to prevent wave action from causing erosion on the upstream slope. In sufficient slope protection, an upstream slope might develop a major erosion problem. Slopes can be stabilized by adding a surface cover, digging and modifying (or regrading) the slope geometry, installing support structures to buttress the slope, or controlling groundwater in slope material through drainage. Though the types are typically involved in high manpower and time, In the recent past, Geosynthetic Cementitious Composite Mats (GCCMs) reinforced with spacer fabric has become increasingly popular because of its lightweight, high strength, and minimal contamination when compared to standard concrete. It is a potential material for use in various civil engineering disciplines, including water construction, pipelining, slope protection, military applications, and so on. In this study, CC slope protection's mechanical characteristics and stability are examined. First, the tensile strength and compressive strength of CC were tested. Short-term laboratory testing results show that the tensile and flexural strength of 3D spacer Geosynthetic Cementitious Composite Mats is relatively higher, and it is very durable. For Geosynthetic Cementitious Composite Mats, there was more constraint in the direction of the load applied, which caused the tensile stress and flexural strength that were created in the matrix to be higher.
