Abstract:
Ultra High Strength Steel-Fiber Reinforced Concrete (UHS-SFRC) is characterized by very high compressive and tensile strength that is about 8 times of ordinary concrete, and high ductility owing to the addition of steel fibers. This paper investigates the relationship existing among the direct tensile strength, flexural tensile strength and splitting tensile strength of UHS-SFRC. Differently from ordinary concrete, it is found that the first cracking strengths in UHS-SFRC obtained through direct tensile test and splitting tensile test are similar, while the strength obtained from flexural tens

Abstract:
&lt;p&gt;For thin-walled tubular members, the zinc coating applied during galvanization may enhance stiffness, thus positively impacting buckling behavior. This study describes the flexural buckling performance of high-strength steel cold-formed circular hollow sections (HSS CFCHS) observed by buckling test on Ø48.3 mm, t = 1.8 mm S960 under three conditions: non-galvanized, galvanized, and galvanized with subsequent zinc coating removal. Specimens were tested across three levels of non-dimensional slenderness. Results show that the zinc coating improves stiffness and modifies buckling behavio

Abstract The industry standard for evaluating the suitability of a fiber-reinforced composite (FRP) has been the ASTM C-581 test procedure. In this test, a coupon is made to simulate the corrosion barrier. Several sample coupons are then immersed into the solution that is being evaluated at the desired test temperature and tested at 1 month, 3 month, 6 month, and 12 month intervals. The tests run are flexural strength, flexural modulus and surface hardness. A new way for evaluating the test coupons is being evaluated and will be discussed in this paper.

Abstract:
Old buildings, in particular, those coming from the first half of 20th century often suffer with increased dampness in masonry coming from different sources. Some of them, however, have aesthetically rendered valued facades which are worth saving. For the design of new alternative mortars for renovation interventions, it is essential to obtain properties of original renders. Mechanical properties of mortars are in general assessed on standardized test samples; however, this approach cannot be always well applicable for in situ taken mortars or rendering materials.

Abstract:
This paper presents results of statistical evaluation of flexural strength of various silicon nitrides and silicon carbides. The interlaboratory comparison involved both analytical and experimental procedures. For instance, two types of reaction bonded silicon nitride from the same production lots were evaluated using different test fixtures and experimental methods. A fairly extensive data base on five types of nitrides and carbides was evaluated using both conventional and advanced statistical techniques. The various differences observed are discussed in the body of the paper.

Abstract:
Concrete for airport rigid pavement construction is generally specified to achieve a minimum characteristic flexural strength of 4.5 MPa and acceptance testing during construction aims to verify this key design assumption. The large flexural beam specimens are cumbersome and the testing is expensive. Consequently, industry desires a more convenient test and a laboratory-based conversion to an estimated flexural strength for acceptance testing during production. This research developed and trialed a protocol for the conversion of indirect tensile strength and compressive strength to estimate th

A novel technique for estimating the critical size of the frontal process zone in ceramics was proposed using a single-edge V-notched beam (SEVNB) test method. A three-point flexure test was carried out on a silicon nitride and two kinds of graphite test specimens with sharp V-shaped notches whose depths varied from 20 to 1,500 μm. The critical local stress was calculated at a critical distance from the notch tip. The critical size of the frontal process zone was determined as the distance between the notch tip and the point where the critical local stress had the same value as the flexural st

Abstract:
Eurocodes for structural designs have been adopted for Sri Lanka. Hence in Sri Lanka, concrete designs need to be in compliance with the relevant Eurocodes – mainly EN1992 (EC2). In EC2, concrete is categorized by its compressive strength. The other strength parameters are derived from the compressive strength using correlations based on empirical data. A recent trend has been the increasing use of blended cement for concrete in certain applications. But the correlations specified in EC2 are based on data probably related to Ordinary Portland Cement (OPC) concrete. It is important to examine w

The objective of this test is to determine the cracking strength and fatigue life of concrete slabs designed and built to FAA standards, hence it is designated the Strength/Fatigue (S/F) test. The experiment considered various combinations of concrete flexural strength (650 vs. 900 psi), slab thickness (9 vs. 12 in), and subgrade strength (CBR 3-4 vs. 7-8). Cracking streng

This research comprises two phases of laboratory testing. Phase 1 was developed to study the (local) interface bond strength of slab specimens through direct shear tests and direct tensile pull-off tests. Phase 2 comprises flexural tests on beam specimens to assess interface shear strength under combined bending and shear.

Flexure tests on specimens featuring longitudinal and transverse grains showed that thermal modification at 167 °C leads to less statistical variability compared to unmodified samples. Additionally, thermal modification leads to a decrease in the transverse flexural strength. On the other hand, the fracture and Janka hardness tests revealed a more pronounced brittleness of the thermally modified samples. The total mode I fracture energy of modified

Decomposition of CH increases porosity and causes significant cracking. The portion of concrete exposed to temperatures higher than 400°C should be repaired or replaced. When s
