We investigated the effect of the method of solidification of aqueous sodium silicate on the formation of its film on the surface of a refractory filler. The structure of liquid-glass films on the surface of a refractory filler cured by convective drying, blowing with carbon dioxide, and with the addition of organic ether (butyl acetate) was studie...

Lucrarea prezintă unele studii privind betoanele realizate cu nisipuri ultrafine şi pudre de cuarţ (0-1200μm) cu sau fără adaos de praf de silice sau cenuşi zburătoare, în vederea realizării unor studii ulterioare a betoanelor ultra rezistente cu adaos de fibre de oţel. Se analizează compoziţiile şi rezistenţele acestor tipuri de betoane.
After three months` trial of Medicinal synthetic Aluminum-magnesium silicate (MSAMS, Nanoparticles) for antiretroviralefficacy, CD4 counts of treated patients increased (P<0.05) from 151.20±42.56 to 458.60±89.55 and their viral loadsdecreased (P<0.05) from 88,333.33± 3609.01 to 4,127.67±680.2. After four months, CD4 counts of patients who were onex...
