Flexural Strength of Float Glass

Applied Mechanics and Materials, 2015
A series of simple and laminated glass tests were carried out under laboratory conditions at the Klokner Institute. The test specimens comprised panes made from float glass with dimensions of 1.1 x 0.36 m. The paper contains experimentally determined characteristic values of flexural strength and estimated design values related to commonly used glass.

Flexural strength and porosity of cements

Nature, 1981
A curious feature of hydraulic cements, such as those based on calcium silicate, calcium aluminate and calcium sulphate, is that they exhibit similarly low flexural strengths, typically between 3 and 10 MPa, despite their differing chemical composition, varying degrees of hydration and contrasting setting mechanisms1–3.

The flexural strength of concrete blockwork

Magazine of Concrete Research, 1980
Synopsis The results of a large number of flexural strength tests on wallettes (small masonry panels for testing) made with a range of commercially available concrete blocks are reported. The relationships between the performance of the wallettes and several properties of the block were investigated as a possible basis for a table of characteristic ...

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.

The Flexural Strength of Artificial Laminate Composite Boards made from Banana Stems

, 2020
Wood is a forest product that is used as raw material for building construction. The increase in demand for wood causes damage to the environment and the ecosystem. Therefore, investigation is needed to find alternative materials that can replace the old
