Time-Dependent Rheological Properties of Cemented Aeolian Sand-Fly Ash Backfill Vary with Particles Size and Plasticizer

Rheological Properties of Cemented Tailing Backfill and the Construction of a Prediction Model

Workability is a key performance criterion for mining cemented tailing backfill, which should be defined in terms of rheological parameters such as yield stress and plastic viscosity. Cemented tailing backfill is basically composed of mill tailings, Portland cement, or blended cement with supplementary cement material (fly ash and blast furnace slag) and water, among others, and it is important...

PROPERTIES OF ALKALI-ACTIVATED FLY ASH CONCRETE BLENDED WITH SLAG

Modeling the Time-Dependent Rheological Properties of Pistachio Butter

Pistachio butter (semi solid paste), which is made from roasted pistachio kernels, is an appropriate alternative to work on because of its high nutritional and economical values. In this study, timedependent flow properties of pistachio butter were determined at two different temperatures (25˚C and 45˚C) for five different formulations (with different levels of emulsifying agents). Forward a...

Modeling mechanical response of cemented EPS-backfill

Cemented backfill is one of geomaterials which is used at a high volume to serve a variety of geo-infrastructure systems, e.g., embankments, retaining walls and approach abutments, and involves the solidification of soil or similar fine aggregate through the addition of a controlled amount of cementitious materials, such as Portland cement, fly ash or lime. A certain volume of expanded polystyr...
