Retarding Admixture

Description
swrr-381 is a highly efficient set retarding concrete admixture. Swrr-381 is used as retarding admixture in concrete where a controlled extention of setting time is required.
Use
• large volume pours
• long haul
• avoiding of cold joints
• construction joints
• difficult placing conditions
• elevated temperature
• revibrated concrete
• ready mix concrete
advantages
swrr-381 provides the following beneficial properties:-
• increased setting time in hot weather
• accelerated hardening after setting
• increased ultimate strengths
• long lasting control over slump loss.
• better surface finish
• chloride free: does not attack reinforcement
• improves work ability : cohesion and extends setting time. Provide protection against delay.
• larger pours: possible with extended placing and compaction times and avoidance of 'cold joint'
• cement savings: can be obtained by maintaining original strength and work ability
