Dear A. Mani, maybe the best place to start is the book

Givant, Steven R.
The structure of relation algebras generated by relativizations.
Contemporary Mathematics, 156.
American Mathematical Society, Providence, RI, 1994. xvi+134 pp.
ISBN 0-8218-5177-2

MR1258306 (95c:03142)

Chapter 7 is dedicated to results on Relation Algebras Generated by 
Equivalence Elements.
