Reinforcing of concrete with steel fibers has some advantages such as decrease and control of cracking, increase of durability and age of concrete, increase of ductility, toughness, tensile, flexural and shear strength of concrete, and some disadvantages such as corrosion of fibers, decrease of workability of concrete, irregularity of distribution and accumulation around the local area.
The main modifications are (typical ranges shown, though great variability has been observed): reduction of set time (by 1 2 h) and diffusivity (by 4 75%), and increase of strength (by 5 25%), and thermal durability (0 30% increase in residual strength).
With many of Mr. Morsi's Islamist supporters finding new motivation during the holy month of Ramadan, which started this week, the largest pro-Morsi sit-in, in the Cairo suburb of Nasr City, swelled to take on an increasing air of durability.
Heat curing decreases the maximum achievable degree of hydration, long-term rate of increase of compressive strength, anti-permeability, and durability of concrete as it ages.
Knowledge of the resulting diversity in the regions involved in stem canker resistance would help to construct resistant varieties with improved durability with the hypothesis that increasing the diversity of genetic factors controlling the resistance would result in an increase of the potential durability of the resistance [ 34].
It has been hypothesized that early initiation of treatment with the combination of oral anti-diabetes agents with complementary mechanisms of action can increase the durability of glycaemic control compared with metformin monotherapy followed by a stepwise addition of oral agents.
In addition, this structural change is accompanied by a decrease of the coefficient of thermal expansion and an increase of the water durability of the glasses with the acids containing a large number of carboxylic groups per molecule.
The results indicate the ability of APF to increase the durability of the GB 20 mix against freeze-thaw cycles.
Rotation or pyramiding of CR genes with different mechanisms of resistance may be used to increase the durability of clubroot resistance if a diverse group of CR genes can be identified and their resistance mechanisms characterized.
It was postulated that partial resistance would retard the evolution of pathogens and thus increase the durability of resistance [ 24, 61].
In this context, the replacement of the liquid electrolyte with quasi-linear polymer electrolyte membranes is here proposed, with the aim of increasing the durability of the device.
