Effect of mineral additives to a gypsum wet deformation

چکیده

The influence of mineral additive, i.e. ground granulated blast-furnace slag on artificial gypsum stone humidity strains has been studied. content was varied in the range from 0 to 0.33 by weight based total amount mixture. measurements were carried out prism samples with dimensions 160x40x40 mm. placed vertically containers water, deformations measured using dial indicators. It established that strain value depends milled blastfurnace slag. A maximum over 0.001 m/m is observed for without additive. relative decreased an increase content. Minimum 0.0003-0.0004 0.05-0.1 and more than 0.27. This fact confirms our assumption water concentrated contacts between individual crystals particles structure a wedging effect contributes low resistance gypsum. values are suggested use as additional indicators its resistance.

Effect of Feed Additives in Growing Lambs Fed Diets Containing Wet Brewers Grains

The study was conducted to evaluate and compare the effects of feed additives on ruminal fermentation, nutrient digestibility and performance of lambs fed diets containing 60% wet brewers grains (WBG). In Experiment 1, two simultaneous trials were conducted. Fifty intact (20.2±0.8 kg BW) lambs were used in a feedlot trial and 10 (rumen cannulated; 32±1 kg BW) in a digestion trial. The pH, volat...

Adsorption of polysaccharide wet-end additives in papermaking systems

The adsorption of polysaccharide guar gum and starch additives and their interactions with cellulosic fiber and fines, as well as soluble and colloidal carbohydrates, present in wood pulp suspensions were investigated by employing HPLC and spectrophotometry. A unique phenomenon, i.e. carbohydrate uptake or ‘substraction’, was observed to occur in a variety of cellulosic systems [whole pulp, was...
