Rockbond Admix 301 (RB A301)

Product Information Sheet:

Description

ROCKBOND ADMIX 301 (RB A301) powder is a blend of chloride free admixtures which has been specially designed to accelerate the early strength development of Portland based cementitious materials. The admixture can be dry mixed with Portland cement, or added to the mix water of cementitious renders, mortars, floor screeds and non flow concretes. The admixture rapidly accelerates the early strength development of non flow cementitious materials at 20ºC, and produces an early strength development at low temperatures. The powder is ready to use, is packaged in 25kg moisture proof, durable bags and has a shelf life of 2 years.
