15 صفحه اولEFFECT OF POLYVINYL ALCOHOL ON FLEXURAL STRENGTH AND SOME IMPORTANT PHYSICALPROPERTIES OFPORTLAND CEMENT PASTE
Abstract: This work was designed to investigate the simultaneous effect of both water-to-cement (W/C) and polymer-to-cement(P/C) ratios on flexural strength of type V Portland cement pastes containing polyvinyl alcohol. The obtained resultsconfirmed the strong effect of W/C-ratio on the effectiveness of the added polymer so that there exist optimum valuesfor both W/C and P/C-ratios. Pastes prep...
متن کاملEFFECT OF OPERATING CONDITIONS ON THE DEHYDRATION OF TOLUENE BY PERVAPORATION USING A POLYVINYL ALCOHOL MEMBRANE
The effects of operating parameters such as feed temperature and permeate-side pressure on the performance of a commercial PVA membrane in the dehydration of toluene by a pervaporation (PV) membrane system is studied in the present work. The results obtained indicate that increasing temperature in the range of 40 to 70 °C and reducing permeate pressure in the range of 1 to 10 mmHg increase memb...
