pumping and shotcreting materials for alkali

Rheology of alkali-activated materials A review

Many alkali-activated materials (AAMs) exhibit poor workability in mixing owing to great viscosity of the paste and fast setting. Chemical admixtures commonly used in Portland cement-based materials such as rheology control additives and superplasticizers show lower efficiency in AAM systems.

Theory of spin-exchange optical pumping of

 · We present a comprehensive theory of nuclear spin polarization of 3 mat He and 129 mat Xe gases by spin-exchange collisions with optically pumped alkali-metal vapors. The most important physical processes considered are (1) spin-conserving spin-exchange collisions between like or unlike alkali-metal atoms (2) spin-destroying collisions of the alkali-metal atoms with each

Table 5.7 Baseline Input Parameters to the Numerical Simulation. The optically pumped alkali atom is labelled as op alkali whereas the hybrid alkali species is labelled as se alkali. The alkali species are enumerated as Na = 0 K = 1 Rb = 2 and Cs = 3. The density ratio of se alkali to op alkali is given by D. The alkali vapor pressure temperature and alkali number densities are determined

Rheology of bauxite-based low-cement shotcreting castables

Continuous research efforts on castable technology since two decades have lead to the transformation of placement mode from vibrating to self-flow to pumping and shotcreting. Shotcreting (an installation process of self-flow castables by combining pumping and shooting) as a high efficient installation technique has demanded castable composition with specific characteristics in terms of rheology.
