TL;DR: In this article, a two parameter fracture model is proposed to include this nonlinear slow crack growth and the critical effective crack extension is dictated by the elastic critical crack tip opening displacement, CTODc.

TL;DR: In this paper, the relationship between crack characteristics and concrete permeability was studied. But the authors focused on the relationship of cracks in concrete with water permeability and did not consider the effect of crack width on concrete's permeability.

TL;DR: In this paper, a composite cement material is prepared from cement material and carbon nanotubes, wherein the carbon-nanotubes are present from about 002 wt % to about 1 0 % based on the weight of the cement material.

TL;DR: In this article, the basic concepts of mechanical properties of fibers - tension, bending constitutive materials mixture proportions - mixing and casting procedures properties of freshly mixed FRC properties of hardened FRC compression, tension and flexure FRC under impact and fatigue loading creep, shrinkage and long-term performance of FRC plastic drying shrinkage fiber-reinforced shotcrete glass fiber reinforced cement (GFRF) thin sheet products slurry infiltrated fiber concrete (SIFCON).

TL;DR: In this article, the reinforcing effect of highly dispersed multiwall carbon nanotubes (MWCNTs) in cement paste matrix has been investigated, and the MWCNTs were effectively dispersed in the mixing water by using a simple, one-step method utilizing ultrasonic energy and a commercially available surfactant.
