The Influence of Curing Conditions on the Physical and Mechanical Properties of Magnesia Phosphate Cements

摘要

The paper brings information on the influence of curing conditions such as humidity,variable temperature and chemical solutions,on the compressive strength and weight variation of the magnesia phosphate binding materials,obtained from magnesite,mono-ammonia phosphate,borax and sand having a granulation ranging between 0.1-1 mm,with or without fly ash addition.The XRD and SEM-EDX analysis were made for obtaining information concerning the reaction products formed in phosphate magnesia binding materials cured in conditions of variable humidity.
