چکیده
The mechanical behavior of earth concrete for sustainable construction has been studied in this paper. effect flax fibers on the fracture monitored using digital image correlation (DIC) and acoustic emission (AE) techniques to better understand process damage mechanism. Three-point bending tests have conducted prismatic specimens with different percentages (0%, 0.3% 0.6%) lengths (12 mm, 24 50 mm) fibers. AE activity energy increased percentage length Moreover, signal parameters varied loading rate mechanisms distinguished. Crack opening resistance also due bridging along developed cracks. Those results show benefits adding enhance ductility concrete.

Mixed Mode Fracture in Reinforced Concrete with Low Volume Fraction of Steel Fibers
An investigation into the mixed mode fracture of steel fiber reinforced concrete (SFRC)beams with one percent volume fraction of steel fiber is presented. A series of notched beams withdifferent notch depths and locations are tested under three-point bending. The test results for apparentfracture toughness, crack trajectories, and fracture energy are presented. The crack paths for SFRCand plain...
متن کاملFracture Behavior and Properties of Functionally Graded Fiber-Reinforced Concrete
In concrete pavements, a single concrete mixture design is selected to resist mechanical loading without attempting to adversely affect the concrete pavement shrinkage, ride quality, or noise attenuation. An alternative approach is to design distinct layers within the concrete pavement surface which have specific functions thus achieving higher performance at a lower cost. The objective of this...
متن کاملMechanical Behavior of Self-Compacting Reinforced Concrete Including Synthetics and Steel Fibers
This paper investigated the effects of combining fibers with self-consolidating concrete (SCC). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (PPS) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. All plans were subjected to fresh concrete tests. For mechanical behavior of...
متن کاملMechanical Behavior of Hybrid Fiber Reinforced High Strength Concrete with Graded Fibers
Brittleness, which was the inherent weakness in High Strength Concrete (HSC), can be avoided by reinforcing the concrete with discontinuous fibers. Reinforcing HSC with more than one fiber is advantageous in an overall improvement of the mechanical performance of the composite. In this experimental study, Hybrid Fiber Reinforced High Strength Concrete (HyFR-HSC) mixes were formed by blending si...
متن کاملStrength and Toughness of Reinforced Concrete with Coated Steel Fibers
The effect of zinc phosphate (ZP) and zinc calcium phosphate (ZCP) coatings on the reinforcing mechanisms of smooth steel fiber in cementitious matrix have been studied. The results of pull out tests illustrated that by coating smooth steel fiber the pull-out load may be increased up to 100%. The effect of zinc phosphate coating on interface bonding was more than zinc-calcium phosphate coating....
