A combination of PEG and glass water was used to fabricate SiC preforms and the effect of the presence of glass water on the microstructure and mechanical properties of the preforms was evaluated by performing compression tests on the preforms. Also, the compressive strength and the hardness of ...
Generally, bricks have high compressive strength in the range of 5.5 N / mm2to 140 N/mm2. If the crushing strength of the bricks is less than 3.5 N/mm2it must not be used. A field test about strength of the bricks is to fall the brick from a height of 1 meter and it must not ...
The research shows that the use of natural fibres had a positive effect on the compressive strength by 27%, while the use of synthetic fibres caused its decrease by 4%. Additionally, it was noticed that the chemical composition, the diameter and the total length of the fibres in the ...

The effect of specimen size on unconfined compressive strength properties of natural deposits is discussed from laboratory tests. The standard deviations of the ratios of qu and E50 values of the S specimens to O (or Ordinary size) specimens (35 mm d and 80 mm h) were in the range of ...
Hydrogels have potential in a number of applications, but for many, mechanical robustness is required. Here, the authors report the preparation of a PVA/PEG hydrogel with a cartilage-inspired structure, with high compressive strength and low coefficient of friction, amongst other properties. ...
For Low Heat Cement (LHC), its hydration reaction properties and compressive strength development were studied by quasi-elastic neutron scattering (QENS) and compressive strength test. In the QENS experiments, the amount of hydration products was estimated and the hydration behavior of LHC was reveale...
Concrete with a strength greater than that of OPC concrete could be produced by replacing up to 10% of the cement with BA. • Using a high dose of BA delays the concrete’s loss of compressive strength at rising temperatures. Abstract This review shows that global sugarcane production reache...
[26] found that the specific strength and specific energy absorption of structures graded by size compression of the unit cell are higher than those of uniform structures. The structures in the above studies were all designed with grading parallel to the load direction. This type of gradient ...
