Sika® Plastomix-250 KH

MID-RANGE WATER REDUCING CONCRETE ADMIXTURE

Description

Sika® Plastomix-250 KH
MID-RANGE WATER REDUCING CONCRETE ADMIXTURE
DESCRIPTION
Sika® Plastomix-250 KH is a newly developed admixture for concrete with mid-range reducing effect. It is
concentrated solution based on Synthetic Polymer and
additives.
USES
Cost effectiveness required for conventional concrete
▪
▪ Where increased workability is required
▪ Use in mixes where cement saving is required
Especially suitable for concrete containing cement
replacements such as PFA (fly ash) or GGBFS (slag)
▪
CHARACTERISTICS / ADVANTAGES
▪ Water reduction up to 15% against control mix
▪ Improved utilization of cement
▪ Improved watertightness
▪ Equal strengths to control mix with less cement
▪ Better improvement for final strength
Compensates for slow early strength gain achieved
by cement replacements (PFA, GGBFS)
▪
▪ Increased workability and placeability
▪ Longer slump retention
APPROVALS / CERTIFICATES
Complies with ASTM C494 – 81 Type A & D
