Behaviour of a cement stone with chemical additions under short high temperature effects
Description
The purpose of the paper is to investigate the influence of different chemical additions used in NPP construction on thermal stability of a cement stone under short- and high-temperature effects. S-3 and dihydroxyphenyl utilized as peptizing agents for increase of placeability of concrete mixtures as well as sodium nitrite utilized as an antifreezing addition at conccreting at low temperatures are used as additions. The investigations were conducted in the 0-900 deg C temperature range divided into 4 ranges. Shrinkage and mass losses of specimens were determined. The obtained data show that specimens with additions are subjected to smaller shrinkage and mass losses as compared with specimens without additions. The highest positive effect is attained in portland cements with active mineral additions
