    abstract = {This study outlines the effect of external salt and internal sulphate (CaSO<sub>4</sub>) on the properties of Self-Compacting Concrete (SSC) containing lime stone. The effect of internal and external salts is combined
with the process of wetting and drying. Three sets of mixes which are reference mix, mixes with internal sulphate
and mixes exposed to external salts respectively are designed with the same mix proportion and maximum sized
aggregate of 10 mm. In order to determine the self compactability features, different tests are adopted such as
the slump flow, V-funnel and the L-box test. The mechanical properties studied in this study are the
compressive strength and ultrasonic pulse velocity. Results show that the compressive strength of mixes with
external salts is larger than mixes with internal sulphates for the ages of 28, 60, 90 and 180 days, respectively
except for the age of 180 days achieved a higher compressive strength. Based on the obtained results, it is clear
that it is possible to produce Self-Compacting Concrete (SCC) from local materials like limestone with good
properties. The SCC is affected by salt attack and its effect by the process of wetting and drying but despite
this fact, SCC still has good properties. The results indicated lime stone can improve salt resistance and can
be used as portland cement replacement.}
