Rheobuild 3520
RHEOBUILD 3520 is a chloride free, superplasticising
admixture. It contains a synthetic polymer specially
designed to impart rheoplastic qualities to concrete
and to improve the pumpability of fresh concrete.
A rheoplastic concrete is a fluid concrete with a slump
value of at least 200 mm or higher, that flows easily
but at the same time is free from segregation, and has
the same water/cement ratio as that of a no-slump
concrete without additive.
RHEOBUILD 3520 has been formulated to meet the
requirements of ASTM C494 for Type G admixture.
