Testing laboratories need to verify their test procedures and testing capability for reliable results. In this study, equivalent samples are prepared by elastomer materials. This paper is described evaluation of tensile results material specimens tested in according ISO 37 DIN 53504 standards. The proficiency conditions, equipment the were evaluated TS EN ISO/IEC 17043 standard. Finally, Z scor...

This study focuses on the effect of the amount of silica fume addition and volume fraction of steel fiber on the engineering properties of cementitious materials. Test variables include dosage of silica fume (5% and 10%), water/cement ratio (0.35 and 0.55) and steel fiber dosage (0.5%, 1.0% and 2.0%). The experimental results included: compressive strength, direct tensile strength, splitting te...

The shape memory alloys present, in the high temperature phase, a super-elastic behaviour : during a super-elastic test, the martensitic transformation is induced by the stress, and a large reversible deformation is observed. With a single crystal, the maximum superelastic deformation reaches 8 to 10%. During the tensile test on a single crystal, only one variant of martensite is induced in the...

Cracked and un-cracked Brazilian disc specimens subjected to diametral compression were used for conducting fracture toughness and tensile strength experiments on a polymer concrete (PC) material. The value of mode I fracture toughness (KIc) was determined from the center- cracked Brazilian disc and the indirect tensile strength (σt) was obtained from the un-cracked Brazilian disc specimen. The...

Natural fibers are widely used as reinforcing material in composites. Pine needles can be used as natural fibers which are abundantly found in the hilly areas of India. A study on tensile test of pine needles and the crack analysis of pine needles short fiber reinforced composites has been presented in this paper.ASTM D638-10 standard is followed for tensile testing and a number of specimen is ...

Abstract Portland composite cement is a type of blended produced by the Indonesian factories where fly ash as one ingredient and production based on efforts to reduce CO 2 emissions in process. This research part sustainability infrastructure development which carried out through use cementitious material manufacture foam concrete. The purpose this paper was contribute understanding early age v...

The internal structure of semi-flexible pavement (SFP) is prone to fatigue damage, which affects its service life. cement mortar admixture has a crucial influence on the resistance SFP. In order explore and study performance SFP, Waterborne Epoxy Resin, emulsified asphalt Carboxyl Latex were selected as admixtures prepare special mortar, effect SFP was evaluated by indirect tensile test. tests ...

This paper describes a nano-scale tensile test to study the fatigue properties of LPCVD silicon nitride thin films using a novel electrostatic actuator design. Mechanical-amplifier devices made in silicon nitride thin films can apply controllable tensile stress (2.0–7.8 GPa) to test structures with relatively low actuation voltages (5.7–35.4 VRMS) at the resonant frequencies of the devices. The...
