Results show that the ideal amount of PPF has enhanced the durability of concrete by reducing the velocity of ultrasonic waves, chloride diffusion, water penetration, and sorptivity.
Initially, therefore, bundles of notes could not be read; but notes being issued from cash machines, or passing from customers to tills, could.The technology remains relatively expensive 20-300 cents a chip), and there is still work to be done hammering out what people want in the way of security standards, durability and the amount of information that can be stored.
Studies showed that adding an appropriate amount of recycled materials might improve the durability of lightweight aggregate concrete.
More complex models were obtained for mechanical durability and the amount of fines, where all factors and most interactions and squared terms were significant.
Another durability factor is the amount of cement in relation to the aggregate (expressed as a three-part ratio cement to fine aggregate to coarse aggregate).
The 3D feature further reduces the amount of silicon required for each wafer without sacrificing strength, durability or performance.
The timber quality produced will be the overriding commercial factor for the near future [ 18], and usually relates to the amount, color and durability of the heartwood [ 4].
One is the problem of durability.
The state endures to create a sense of durability.
In Pittsburgh, Jerome Bettis was criticized for his lack of durability.
