ABSTRACT: Pine aggregate concrete based on 12 quartz or pummiua sands and
Portland cement of 350 kg per Cm activity could produce high
quality concrete suitable for prestressed construct-.1ons. Vibro-
ground cement intensifies hardening of concrete in the initial
stages and by that reduces the time during which reinforcement
should be kept under tens-ion. At the same time vibzo-graund cement
slightly increases shrinking. Fine aggregate concretes based on pit
sand in comparison with concretes based on .-znashed sand have
lower elasticity (35-50%) than values given in _NiTU 123-55. These
should be taken into acocunt-wheL- evaluating deformations in
prestressed constructiona based on fine aggregates. Fine aggregate
light concretes have slightly higher elasticity than light
concretes based on porous sr~nd and ballabt. Shrinking of high

quality fine aggregate concretes is many times higher than
shrinking in concretes based on sand and ballast. Shrinking of
fine aggregate concrete based on sana from pumice is 13% higher
than shrinking in concretes based on fine aggregate and quartz
sand. Calculations show that in prestressed con-structions made
from fine aggregate concrete where the grains do not exceed 5mm
in size if no special gradation is performed and when 600kgs per
M3 cement is used the loss of pre-tensioning due to "sluggishness"
could be higher than p;rmissable Values. High strength values of
concrete are obtained by the use of cement with increased activity
and slow mobility of concrete mix. Under these conditions the
cement requirements are between 4,110-500kgs per rc% Sizes of the
aggregate depend on the proximi-t-y of the ratnforcemeat bars and
the thickness of the product, Careful grarnalat:.:)n of aggregates
is required. Table I gives values for hardening under controlled
curing conditions during a three mont~z period fo:6~ concrete of
