Effect of Cured Time on Creep of Lightweight Aggregate Concrete
Creep and shrinkage are such properties that will occur in concrete when they are under load and exposed to surrounding. Since this property will cause deformation which may decrease the design strength of the concrete, it is necessary to do have more knowledge on this phenomenon. So, we will study the effect of creep on 7 and 14 days of cured time of specimens which sealed or unsealed will be ...
متن کاملThe Effect of Sulphate on Length Change of Concrete
Sulphates usually affect calcium aluminates in cements. Sulphate ions might have negative effects on cement hydration and it would be a reason of decrease in cement strength. In this study, the effects of Na2SO4 solution on the concretes made from OPC with oil shale ash (OSA) addition (0, 15 and 30%) were investigated. Concretes with 15% OSA gave the lowest value of Length Change Factor (LCF). ...
متن کاملTetanus Cured by Magnesium Sulphate
The patient?a Hindu male child aged 4, admitted on 31st October, 1933, for treatment of an ulcer on his head. On examination the following signs were observed; these had apparently escaped the notice of his parents. He had difficulty in swallowing, could only partially open his mouth and his eyes were partly closed, the lower extremities were stiff and abdomen rigid; these signs were detected a...
متن کاملTHE EFFECT OF IONIC STRENGTH ON THE BINDING OF SODIUM N-DODECYL SULPHATE TO ASPERGILLUS NIGER CATALASE
The binding of sodium n-dodecyl sulphate (SDS) to Aspergillus niger catalase in various ionic strengths at pH 6.4 and a temperature of 27? and 37?C has been studied over a range of SDS concentrations using equilibrium dialysis and fluorescence spectroscopy techniques. The binding data were used and interpreted in terms of theoretical models (Scatchard Equation and Wyman Binding Potential). ...
متن کاملThe 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...
