Synthesis, Characterization, and Recyclability of a Functional Jute-Based Geopolymer Composite

Frontiers in Built Environment, 2021
This study describes the properties of geopolymer composites reinforced with bidirectional jute fibers. Their flexural strength is 12 MPa, four times higher than the strength of non-reinforced reference geopolymers.

Experimental Study of Rubberized Concrete Stress-Strain Behavior for Improving Constitutive Models

Materials, 2018
Inclusion of rubber into concrete changes its behavior and the established shape of its stress-strain curve. Existing constitutive stress-strain models for concrete are not valid in case of rubberized concrete, and currently available modified models ...
