Sodium Sulphate Effect on Cement Produced with Building Stone Waste

Resistance of class C fly ash belite cement to simulated sodium sulphate radioactive liquid waste attack.

The resistance of class C fly ash belite cement (FABC-2-W) to concentrated sodium sulphate salts associated with low level wastes (LLW) and medium level wastes (MLW) is discussed. This study was carried out according to the Koch and Steinegger methodology by testing the flexural strength of mortars immersed in simulated radioactive liquid waste rich in sulphate (48,000 ppm) and demineralised wa...

The Unexpected Effect of Sodium Arsenate on the Interaction between Histone H1 and Sodium N-Dodecyl Sulphate

A Study was made on the interaction between histon H1 and sodium n-dodecyl sulphate (SDS) in the presence of sodium arsenate inside a phosphate buffer of pH 6.4, using spectroscopy and equilibrium dialysis at 27 °C. The binding data has been used to obtain the gibbs free energy in terms of a theoretical model based on the Wyman binding potential. The binding data hs been analysed...

Effect on Surface Temperature Reduction of Asphalt Pavements with Cement–Based Materials Containing Ceramic Waste Powder

THE INFLUENCE OF CHARGE DENSITY ON THE INTERACTION BETWEEN SODIUM NDUDECYL SULPHATE (SDS) WITH H1

The binding data for the interaction of SDS with HI, in aqueous solution at various ionic strengths have been measured by equlibrium dialysis, and investigated spectroscapicaliy. The effect of charge density on the interaction is shown to be of considerable interest. The presence of NaCl causes conformational changes on the structure of HI; whereas this phenomena seems to become more intens...

Influence of Fineness of Recycled Glass Waste and Slag on Compressive Strength of Sulphate Resisting Cement Mortars

Method: At first, two optimized fineness levels were attained for both cement substituting materials used in this study (GGW as glass fine ˂ 38μm (GF), glass superfine ˂ 25μm (GSF) and EAFS as slag fine ˂ 75μm (SF), slag superfine ˂ 32μm (SSF)). In addition to control mortar (CM), four types of binary mortar mixtures were cast by substituting cement 5-20% with GGW (GF and GSF) and 10-30% with E...
