Laboratory Investigation of Dry Lean Concrete with Copper Slag
No full textAt present about 33 million tonnes of copper slag is generated annually worldwide, India
contributing 6 to 6.5 million tones of this slag. As per scientific estimate, for every tonne of
copper metal produced, around 1.8-2.2 tonnes of slag is generated. In states like Kerala,
Maharashtra and Gujarat, sand mining in rivers has already been banned owing to its
disastrous impact ecology. “Therefore, slag has a big potential of getting developed as a
suitable alternative material to these resources”. With increasing shortage of river sand and
natural aggregates across the country, construction sector is under tremendous pressure to
explore alternative to these basic construction material to meeting growing demand of
infrastructure demands.
The reuse of waste materials derived from industry waste is growing all over the world. One
of the most environmentally responsible ways of meeting the challenges of sustainability in
construction is the use of slag in new construction. The main objective of the study is to
investigate the effect of using copper slag in lieu of natural fine aggregate on strength
properties of Dry lean Concrete.
Dry Lean Concrete (DLC) is an important part of modern rigid pavement. It is a plain
concrete with a large ratio of aggregate to cement than conventional concrete and generally
used as a base/sub-base of rigid pavement. The compaction of DLC is done under 10 to 12T
vibratory roller in field , that’s why it is also known as Roller – Compacted Concrete or RCC
concrete.
From all the combination it is observed that Density is maximum(2.571 g/cc) of the mix (SCS-
20-80) where 20% Fine Aggregate and 80% Copper Slag at 5.0% moisture content from
this we can say that density of mix increases with the increases of copper slag in the mix and
it uses less moisture content. It is due to the density of copper slag is more that the densities
of sand and copper slag also having a less water absorption.
From all the combinations of mixes it observed that Compressive Strength of 28days is
maximum(22.49 N/mm2) of the mix S-CS-60-40 at 5.0% moisture content
From all combination it is concluded that although 28days compressive strength is Maximum
in the Mix S-CS-60-40 but compressive strength (28 days) of Mixes S-CS-40-60 & S-CS-20-
80 are also very near to the maximum strength 22.35 N/mm2 and 21.98 N/mm2 respectively
at the same moisture content
Anomalous structure and dynamics of the Gaussian-core fluid
No full textIt is known that there are thermodynamic states for which the Gaussian-core fluid displays anomalous properties such as expansion upon isobaric cooling (density anomaly) and increased single-particle mobility upon isothermal compression (self-diffusivity anomaly). Here, we investigate how temperature and density affect its short-range translational structural order, as characterized by the two-body excess entropy. We find that there is a wide range of conditions for which the short-range translational order of the Gaussian-core fluid decreases upon isothermal compression (structural order anomaly). As we show, the origin of the structural anomaly is qualitatively similar to that of other anomalous fluids (e.g., water or colloids with short-range attractions) and is connected to how compression affects static correlations at different length scales. Interestingly, we find that the self-diffusivity of the Gaussian-core fluid obeys a scaling relationship with the two-body excess entropy that is very similar to the one observed for a variety of simple liquids. One consequence of this relationship is that the state points for which structural, self-diffusivity, and density anomalies of the Gaussian-core fluid occur appear as cascading regions on the temperature-density plane; a phenomenon observed earlier for models of waterlike fluids. There are, however, key differences between the anomalies of Gaussian-core and waterlike fluids, and we discuss how those can be qualitatively understood by considering the respective interparticle potentials of these models. Finally, we note that the self-diffusivity of the Gaussian-core fluid obeys different scaling laws depending on whether the two-body or total excess entropy is considered. This finding, which deserves more comprehensive future study, appears to underscore the significance of higher-body correlations for the behavior of fluids with bounded interactions.Intramural NIH HHSChemical Engineerin
A Unified Shell model for Buoyancy-Driven Turbulence
No full textWe construct a unified shell model for stably stratified and convective turbulence. Shell model simulation of stably stratified flow in turbulent regime exhibit Bolgiano-Obukhbov (BO) scaling in which the kinetic energy spectrum varies as . However, simulation of convective turbulence shows Kolmogorov's spectrum. These results are consistent with the direct numerical simulations of Kumar {\em et al.} [Phys. Rev. E {\bf 90}, 023016 (2014)]. We also observe a dual scaling ( and ) for a limited range of parameters in stably stratified flow

Multivariate Quantitative Representativeness and Constituency Analysis of Ecological Observation Networks
Author: Jitendra (Jitu) Kumar ([email protected]), Oak Ridge National Laboratory
Regional and global ecological research networks, representing coordinated and standardized as well as adhoc networks of observation sites, provide valuable observations necessary for ecological modeling and synthesis studies. Studies conducted across observational networks strive to scale up their results to larger areas, trying to reach conclusions that are valid throughout regional, continental, and even global scales. Network representativeness and constituency can show how well conditions at those locations represent conditions elsewhere within a larger area containing the network and can be used to help scale-up results over larger regions.
Representativeness: Euclidean distance between two sites plotted in multivariate environmental space can be used as an inverse measure of multivariate similarity to quantify representativeness. Close sites in environmental space have a similar combination of environmental factors, and therefore are highly representative of each other.
Constituency: For any site in the network, its Constituency represent all locations that are best represented by the multivariate environmental drivers at that site.

Laboratory investigations of dense bituminous macadam (grade 1) mix using different types of additives
No full textM. E. Civil (Infrastructure Engineering) ThesisIndia has a road network of over 4,236,000 kilometres, the third largest in the world. The road transport carries close to 85% of passenger traffic and 70% of freight transport. The properties of bitumen and bituminous mixes can be improved to meet requirements of any pavement with the incorporation of certain additives or a blend of additives. Bituminous mixes can be prepared and used in a pavement section for a bituminous binder course using different types of additives such as Polymers, Crumb Rubber and waste materials like discarded tube tyres, plastic bottles and rice husk ash. Modified bituminous mixes are expected to give higher life of surfacing depending upon degree of modification and type of additives used.
The consumption of plastics is increasing day by day. Nearly 50 to 60% of the total plastics are consumed for packing. Once used plastic materials are generally thrown out as they do not undergo bio-decomposition. Hence, they are either land filled or incinerated. Both are not eco-friendly processes as they pollute the land and the air. Similarly, waste tyres in India are categorized as solid hazardous waste. It is estimated that about 60% of waste tyres are disposed via unknown routes in the urban as well as rural areas. The hazards of waste tyres include- air pollution associated with open burning of tyres, aesthetic pollution caused by waste tyre stockpiles and illegal waste tyre collecting and other impacts such as alterations in hydrological regimes when gullies and watercourses become waste sites.
The present study aims at developing bituminous mixes for the Dense Bituminous Macadam (DBM) Grade 1 incorporating the plastic wastes, waste tyre tubes and rice husk ash as partial replacement of the bitumen content. Also the study focuses on the DBM Grade 1 mixes with different blends by using Crumb Rubber Modified Bitumen (CRMB) and Polymer Modified Bitumen (PMB). In this study, the Stability-Flow analysis for the various DBM Grade 1 mixtures with modified binders and with different percentage replacement of bitumen with plastic wastes, waste tyre tubes and rice husk ash are reported. It is found that of the three materials used, replacement of OBC by 10% discarded tyre tube has the highest stability value. The optimum content of CRMB and PMB for use in DBM Grade 1 mix is 5%. Also the bituminous mixes of DBM Grade 1 with 5% PMB having 40% stone dust shows the maximum stability value and the bituminous mixes of DBM Grade 1 with 5% CRMB having 44% stone dust shows the maximum stability value.Civil Engineering Department, Thapar University, Patial
