Retarding and Plasticising Concrete Admixture
DESCRIPTION
Deltamix CR is a chloride free brown solution water reducing admixture based on selected lignosulphonate materials, which instantly disperses in water. Deltamix CR disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively. Delay the initial hydration of the cement, which will also delay the setting time of the concrete with no adverse effect on subsequent stiffening and strength gain.
USES
Deltamic CR improves the effectiveness of water content of a concrete mix and to extend working times of concrete by maintaining its workability, and particularly suitable for use in mixes with low cohesion.
STANDARD COMPLIANCE
Deltamix CR conforms with BS 5075 Part 1, ASTM C494 as Type B and Type D
ADVANTAGES
- Improve compressive strengths at all ages and enhances durability
- Increase strength, higher strength without increase in cement content or reduction in workability
- Cement saving, strength specifications and workability can be maintained with less cement
- Improve quality, denser close-texture concrete improves durability and surface finishes
- Higher Cohesion, risk of segregation and bleeding minimized
- Chloride free, safe in prestressed concreted and with sulphate-resisting cements and marine aggregates
Instruction FOR USE
Application
Always contact Deltacrete to do the trials before using Deltamix CR to ensure the compatibility of the product in the concrete mixes and to get the right dosage.
Dosage
The optimum dosage of Deltamix CR should always be determined by trials using materials and conditions that will be experienced in use. The normal dosage range is 0.3 to 0.6 litres/100 kg of Portland Cement.
