(1) Test results showed that the RCA concrete mixes, with the RCA substitution of 23% (S = 1), 47% (S = 2), and 73% (S = 3), proportioned by the modified EMV method, exhibited a 27, 9, and 3% decrease, respectively, in the drying shrinkage at 585 days in comparison to the companion natural aggregate concrete mix.
On the other hand, the addition of scrap rubber, from 10%to40%0%, had a beneficial effect in decreasing the drying shrinkage of SCMs produced at low w/p (water-powder) ratios.
Although the roots weight did not decrease much under −P stress, there was a significant decrease in the dry weight of the roots and shoots under ++P stress.
The undiluted flue gas containing 11.4% CO2 caused a decrease in the dry weight production compared with lower flue gas concentrations (2.5 and 6.7%).
Both theory and experiments show a decrease in the dry restitution coefficient with an increase in impact velocity, mainly due to increased inelastic losses in the porous material.
A decrease in the dry unit weight may be due to the lower specific gravity of the SDA, while an increase in the optimum moisture content may be as a result of water needed to be hydrated.
These features guarantee the survival of the species in these unstable environments, especially in relation to the volume of water that accumulates in the rainy season and its decrease in the dry season or by anthropogenic action.
Generally, the decrease in the dry matter degradability, total gas, and methane production upon addition of flavonoids could be attributed to the antimicrobial action of flavonoids [ 33, 34].
Cross-linking of this type of PEMU by heating to 215 °C for 2 h caused a decrease in the dry thickness to 119 nm.
A moderately confident projection exists for an increase in the frequency of cyclones, while rainfall, although maintaining a similar annual mean, will increase in the wet season and decrease in the dry season (11).
