Performance and properties of structural concrete made with corex slag
… recently a new product called Ground Granulated Corex Slag (GGCS) has become available on the market in the Western Cape Province. The objective of this research is to characterise the properties of this new product in concrete. In this study, the properties of corex slag concrete were compared …

Alkali-Aggregate reaction in Western Cape concrete
… and 40 percent fly ash and 40, 50 and 60 percent corex slag were used. It was found that all the mixes mitigated the ASR expansion to acceptable levels, that is below the 0.10% expansion, while increasing cement extender levels reduced the expansion further. It was also found that fly ash was more …

Analysis of the thermodynamic determinants of protein fold specificity in the denatured state ensemble
… protein folding is discussed. In this work, the COREX algorithm, used until now to model the native state ensemble, was for the first time used to model the denatured state ensembles and investigate the relationship between denatured ensemble energetics and sequences, as well as between denatured …

Heat transfer through anaerobic digester concrete tank walls
… forming part of the study are cement, corex slag, water, fine and coarse aggregate. The study showed that the aggregates have a greater influence on the thermal conductivity than the other constituents. It also showed that the mineral composition of the aggregates has a greater effect …

Properties of Western Cape concrete with metakaolin
… industry which depends on the use of Corex slag (GGCS) from a source that can be variable. This raises the need to investigate the properties of concrete with metakaolin, in order to assess its potential for use as an alternative SCM in the Western Cape. The properties of concrete with …

Carbonation and permeability characteristics of modern South African concretes
… furnace slag (BS) (20%- 60% in 10% increments), Corex slag (CS) (20%-60% in 20% increments), and limestone (10% and 20%). For ternary blends, the concrete was limited to three mixes, that is, 5% SF with either 25% FA, 25% BS or 25% CS. Furthermore, two commercial blended cement products were …

Service life extension of reinforced concrete structures using hydrophobic impregnation
… (CEM I 52.5N, Fly-ash (FA), Ground granulated Corex slag (GGCS) and CEM III/B 42.5N) were selected. Hence, a total of 8 main (normal) concrete mixes and 4 poor quality mixes were used. Poor quality concrete was produced by exposing the concrete specimens to relatively high temperature at early …

A thermodynamic definition of protein folds
Modern techniques in structural biology, like homology modeling, protein threading, protein fold classification, and homology detection have proven extremely useful. For example, they have provided us with evolutionary information about protein homology which has in some many cases lead directly to …
