Abstract

We studied the effect of adding (Dodecyl Benzene Ammonium Sulphonate) as afunction of
different ratio( 1% - 8%) where these additives added to the matrix of Iraqi cement (Om Quasar
factory for cement) .All the prepared samples were in form of cubic with aside ( 50 mm ) long and
evaluated as afunction of dipping time in distilled water . All the prepared samples had a proportion
of cement to sand ). The obtained results showed that the (Dodecyl Benzene Ammonium
Sulphonate) tends to decrease the compressive strength of the modified cement mixture with
increasing curing time with distilled water where the amount of decrease linearly when curing time is
21 days but less decrease in compressive strength obtained when curing time is 3 and 7 days while
the relative compressive strength decrease linearly also as a function of adding ratio when curing time
is 3 days. Also surfactant (Dodecyl Benzene Ammonium Sulphonate) acting as plasticizer on cement
matrix leading to flexible cement. Finally the obtained results showed that there is a critical ratio of
(Dodecyl Benzene Ammonium Sulphonate) depending on the kind of used cement and curing
conditions enabling us to use this modified cement in many application specially in industrial and oil
for the high workability of this cement and the less water needs.
