Conplast R*
Conplast R a brown chloride free liquid is based on a hydroxycarboxylic acid derivative 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. This effect can be used to improve work ability, to increase ultimate strengths or to facilitate a reduction in the cement content.
The retarding properties of Conplast R can also be beneficial in concrete where high cement content or high temperatures are involved. Cold joints in continuous pours may be avoided and the use of lower cement contents will reduce heat of hydration.
Conplast R is particularly suitable for cohesive and cement rich mixes. For lean mixes which are prone to segregation Conplast RP264*† may prove more suitable.
Description
Uses
To increase the work ability and/or strength of concrete of a given cement content whilst increasing its initial and final setting time. To facilitate the production of high quality concrete of improved durability and water tightness.
Dosage
The optimum dosage of Conplast R to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use.The normal dosage range is 0.3 to 0.6 litres/100 kg of cementitious material, including PFA, GGBFS or micro silica.
Storage
Conplast R has a minimum shelf life of 12 months provided the temperature is kept within the range of 2°C to 50°C.Should the temperature of the product fall outside this range then contact Fosroc for advice.
