The flexural strength and microhardness of YBa2Cu3O6+?

Journal of Materials Science, 1990
The flexural strengths of rectangular YBa2Cu3O6+δ bars, prepared from mixed oxides and carbonates or spray-dried precursors, have been measured at room temperature and at 77 K. Strengths ranged from 17.8 to 57.6 M Pa at room temperature, depending on processing history, and were 20% greater when measured at 77 K.

Flexural strength of metakaolin ferrocement

Composites Part B: Engineering, 2013
Abstract Flexural strength of metakaolin ferrocements was evaluated through laboratory investigation. Reference mortar with OPC of 43 grade and metakaolin mortars with 5–25% metakaolin replacement in the increments of 5% with cement were made. Constant water to cementitious ratio of 0.5 was maintained for all the mortars.

Flexure strength of repaired dental composites

European Journal of Oral Sciences, 1986
Abstract — A study was conducted to determine differences in flexure strength between unrepaired and repaired dental composite bars. Four groups, each consisting of 10 samples, were investigated. Group A consisted of unrepaired samples, while groups B‐D consisted of samples which had been cut to lengths of 17.5 mm and repaired to a total length of 35.0

Flexural Strength of Profiled Beams

Journal of Structural Engineering, 1994
A construction technique that uses steel decking as permanent and integral shuttering for the sides and soffits of reinforced concrete beams is described. Experimental tests on large‐scale profiled beams have shown that the side steel decking can substantially increase both the flexural strength and the ductility, as well as the shear strength of the ...

Flexural strength of joined and intact amalgam

Acta Odontologica Scandinavica, 1982
Flexural strength of joined and intact specimens of five different alloys were measured. The same alloys were also tested in compression. Joined specimens were also tested in compression. Joined specimens were made by condensing fresh amalgam against the ground surface of 1 week old amalgams.

The Ductile Behaviour Including Flexural Strength of High-Strength Concrete Members Subjected to Flexure

"SP-172: High-Performance Concrete - Proceedings: ACI International Conference, Malaysia 1997", 1999
Fifteen high-strength concrete beams were tested under concentrated load at two points to investigate their ductile behavior including flexural strength with various compressive stress distribution. Six high strength concrete beams were tested to investigate the minimum reinforcement ratios requirements for high strength concrete.

Flexural Strength of WT Sections

Engineering Journal, 1992
WT sections are commonly used as chord members in lightly and moderately loaded roof and floor trusses. In this application, these members are subjected to combined axial and flexural loads. The design of these sections for flexural loads was not specifically addressed in the ASD Specification.

Strength of ligthweight ferrocement in flexure

Cement and Concrete Composites, 1991
Abstract Lightweight ferrocement has been made by replacing sand in the cement mortar by foamed blast-furnace slag (fbs) from 0 to 100% in steps of 20%. Ferrocement specimens of rectangular section, 200 mm wide × 25 mm thick, have been cast using this lightweight mortar and containing symmetrically distributed 2, 4 or 6 layers of 4 × 22 gauge ...

Strength of FRC Corbels in Flexure

Journal of Structural Engineering, 1994
Tests were carried out on 38150×150×200mm reinforced concrete corbels subjected to vertical loading. Steel fibers were used as shear reinforcement in 28 corbels. Parameters varied included volumes of main bars and fibrous reinforcements, effective depth or cover to main bars, and shear span.
