Analysis of the effect of volume on the bending strength of the Spanish scot and laricio pine timber
Since the beginning of the XX century it has been recognized that the bending strength of timber is affected by the size of the specimen. In the present work the influence of depth (h) and thickness (t) on the characteristic bending strength (fk) of both Scot (Pinus sylvestris) and Laricio (Pinus nigra) pine Spanish g…
Historical notes about the development of cement normalization In European Union
The European Standard EN 197-1:2000 for Cement, prepared by CEN/TC 51, is from now (2002-04-01) onwards, compulsory in all the countries of the European Union. It has been considered suitable to expose some details on the historical development of the steps and difficulties during the elaboration of the standard ENV 1…

Data Variability in Rheological Measurement of Semi-Solid Foods: Effects of Loading Normal Force
Previous studies involving rheological measurement of semi-solid foods have reported a large amount of data variability, but have focused little on understanding the cause of such variability. This project examined whether differences in normal force have an effect on the variability of rheological measurements. Exper…
Viscoelastic Behavior of Disperse Systems with Silicone Oil and Different Fillers
The rheological behavior of model suspensions with the silicone oil M20000 and different concentrations of Cab-o-sil TS 720 resp. Durcal 5 are compared. The increase of the Cab-o-sil concentration changes the flow behavior of the suspension from shear-thinning, to pseudoplastic, and to plastic flow behavior. The first…

The Effect of Yellowing Inhibitor Total Charge on The Rheology of Paper Coating
New compounds, called inhibitors, provide anti-yellowing effect for mechanical pulps and papers, when added to the coating formulation. The rheology of coating mixtures, which contain clay, ground calcium carbonate, starch, latex, inhibitors and other minor additives, affects to a certain extent the final quality of t…
Evolution of the hydration in cements with additions
In this paper, the hydration mechanism of portland cement pastes with limestone, quartz and natural pozzolan (80/20 weight) was analized. The techniques used were nonevaporable water content, pozzolanic activity and X-ray diffraction. Results show that filler effect increases initially the amount of hydration products…

Physical, mechanical and microscopic characterization of cold bonded fly ash lightweight aggregates
This study presents the results of the different tests carried out on fly ash lightweight aggregates produced with three different kinds of binders: Lime, Portland cement and Pozzolan Portland cement. The elaboration process used for the aggregates consisted in an agglomeration system by agitation under cold bonded ha…

Zinc Phosphate (Zn3(PO4)2) by XPS
The XPS spectra of zinc phosphate were collected on a VSW HA 150 using x-radiation. The valence band is dominated by the intense Zn 3d region but one of the two characteristic, phosphate features can be identified in the region below 20 eV binding energy and is consistent with previous data. The reported regions are a…
Processing and Characterization of NiTi Porous SMA by Elevated Pressure Sintering
Currently, three methods are commonly used for producing porous NiTi shape memory alloys (SMAs) from elemental powders. These include conventional sintering, Self-propagating High temperature Synthesis (SHS), and sintering at elevated pressure via a Hot Isostatic Press (HIP). Conventional sintering requires long heati…
Formation of Sepiolite-Palygorskite and Related Minerals from Solution
Abstract Most of the world's sepiolite-palyg orskite precipitates in lacustrine and perimarine environments. Although these minerals can transform from precursor minerals, the most common formation mechanism involves crystallization from solution. In this study, equilibrium activity diagrams are calculated for sepioli…
A structural study of the (Na 1− x K x ) 0.5 Bi 0.5 TiO 3 perovskite series as a function of substitution ( x ) and temperature
Rietveld neutron powder profile analysis of the (Na 1− x K x ) 0.5 Bi 0.5 TiO 3 (NKBT) series ( x =0, 0.2, 0.4, 0.5, 0.6, 0.8, 1.0) is reported over the temperature range 293–993 K. A detailed characterization of the structures and phase transitions occurring across this series as a function of temperature has been ma…
Thermal Storage/Release, Durability, and Temperature Sensing Properties of Thermostatic Fabrics Treated with Octadecane-Containing Microcapsules
To develop a thermostatic fabric, a 100% polyester fabric is treated with octadecane- containing microcapsules by a knife-over-roll coating process. The amount of heat content increases as the concentration of microcapsules increases. and it decreases as the temper ature and time increase. The surfactant treatment at…
