Abstract
Investigations about the deformation properties
(shrinkage and swelling) of oil shale ash were carried
out in co-operation with the Tallinn Technical University
(Estonia) and Technical Research Centre of Finland.
Deformation behaviour of concrete with two types of burnt
oil shale cements in fresh and hardened state were
studied. The special cement was made from Estonian
Portland cement clinker, natural gypsum and an expansion
additive, burnt oil shale, which is a by-product of
energy plants. The comparison was made by using
shrinkage reducing additive. Conclusions about expansion
of concrete stored in water, about drying shrinkage of
hardened concrete and about total strain after water
storage and followed storage in dry environment (50 % RH)
were given.
