Description
Cement Admixture Fosroc Conplast R is a chloride free water reducing admixture based on selected hydroxycarboxylic materials. It is supplied as a brown solution which instantly disperses in water.
Conplast R disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively. The initial hydration of the cement is also delayed, resulting in a delay in the setting time of the concrete with no adverse effect on subsequent stiffening and strength gain.
Uses
* To improve the effectiveness of the water content of a concrete mix.
* To extend the setting time of concrete, extending working times and minimising delay problems.
* To extend the working life of semi-dry concrete screeds
* Particularly suitable for use in mixes having fly ash and also improve the working life of semi dry concrete mixes, specifically RCC ( Roller Compacted Concrete) type of mixes.
Advantages
* Water reduction significantly improves compressive strengths at all ages and enhances durability through the production of low permeability concrete
* Controlled retardation extends working life and stiffening time for ease of construction
* Control of stiffening improves slip forming and assists in preventing the formation of cold joints in large pours
* Allows specified strength grades to be met at reduced cement content or increased workability
* Chloride free, safe for use in prestressed and reinforced concrete
