The impact of alpha radiation on cements used to encapsulate intermediate-level waste (ILW) is not well understood. ILW wastes can contain high levels alpha-emitting radionuclides, meaning that the grouts them are exposed significant ionising radiation. Thus, a damaged region could develop in grout adjacent species. This work attempted recreate this behaviour through nonradioactive 4He2+ ion-ac...

In this paper, a numerical investigation of the effects grout parameters on load response concrete pile-grout systems in soft clay is presented. The study examines influence diameter and depth bearing capacity pile under vertical lateral loads. research findings indicate that grouting can enhance single system by up to 27% loads 51% loads, depending used. This due grout's ability fill voids soi...

a new type of infilled frame has been recently proposed. it has a frictional sliding fuse, horizontally installed at the mid-height of the infill. it has already shown that such infilled frames have higher ductility, strength and damping ratio as well as more enhanced hysteresis cycles, compared with regular infilled frames. this experimental paper is focused on the influence of gravitational l...

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

INTRODUCTION Household products are usually safe to use. Adverse events arising from their use are mostly reported in patients with pre-existing atopy or pulmonary problems and usually only after a prolonged exposure to such products. We report the case of a patient with no prior problems who developed significant side effects from a single exposure to a domestic product. CASE PRESENTATION A ...

the effects of cementation and the physical properties of grains on the shear behavior of grouted sands are investigated in this paper. the consolidated-undrained triaxial shear behavior of three grouted carbonate sands with different physical properties, including particle size distribution, particle shape and void ratio, was studied. two sands were obtained from the north shores of the persia...
