Pore Structure Evolution and Its Effect on Strength Development of Sulfate-Containing Cemented Paste Backfill
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...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولEffect of Alkali Content on Strength and Microstructure ofGGBFS Paste
The effect of alkali content (% K2O + %Na2O) on the mechanical properties of alkali activated blast furnace paste has been investigated. The paper presents the study on workability, compressive strength, split tensile strength and microstructure of alkali activated blast furnace slag paste specimens prepared by using of sodium silicate and potassium hydroxide solution as activators. The experim...
متن کاملMultiphysics 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...
