چکیده
In order to understand the changes in properties of cemented tailings backfill (CTB) during curing process. this paper, CTB samples with a cement-sand ratio 1:6 were prepared and cured for 3, 5, 7, 14, 21, 28, 60, 140 200 days respectively, then series uniaxial compression tests carried out. Then stress-strain relationship, compressive properties, elastic modulus, etc. different age analyzed. Results indicate that when are at short is shorter than 7 days, mainly shows plasticity, while as increases, samples' deformation experienced four stages. And unconfined strength (UCS) modulus elasticity keep increasing, but growth rate gradually slows down.

Multiphysics Modeling and Simulation of Strength Development and Distribution in Cemented Tailings Backfill Structures
Cemented paste backfill structures are complex underground cementitious structures. After fresh cemented paste backfill (CPB; a mix of tailings, binder and water) is poured into underground stopes (mined-out voids), its strength which is a key mechanical design criterion of CPB structures, gradually develops with time. The development of CPB strength is governed by the coupled thermo-hydro-mech...
متن کاملStrength Characteristics and Failure Mechanism of Cemented Super-Fine Unclassified Tailings Backfill
This experimental study investigates the strength characteristics of cemented super-fine unclassified tailings backfill (CSUTB) and its failure mechanism. Physical and chemical properties of tailings from the Zhongguan Iron Mine (ZGIM) were tested. A series of uniaxial compressive strength (UCS) tests was conducted to determine the relationships between UCS of CSUTB and three factors of cement-...

In this study, the effects of the initial sulfate content on the properties of cemented paste backfill (CPB) made from coarse tailings has been investigated via mercury intrusion porosimetry. The combined effects of the sulfate content and curing time on the total porosity, pore size distribution, and unconfined compressive strength of the produced material were discussed. It was found that the...
متن کاملModeling 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...
متن کاملExperimental and Numerical Study on Tensile Strength of Concrete under Different Strain Rates
The dynamic characterization of concrete is fundamental to understand the material behavior in case of heavy earthquakes and dynamic events. The implementation of material constitutive law is of capital importance for the numerical simulation of the dynamic processes as those caused by earthquakes. Splitting tensile concrete specimens were tested at strain rates of 10(-7) s(-1) to 10(-4) s(-1) ...
