TEC MIX 240
TEC MIX 240
RETARDED SUPER PLASTICIZER
KEY BENEFITS AND FEATURES
- Specially formulated retarder cum super plasticizer for Ready mix plants.
- TecR Mix 240 disperses the fine particles in concrete mixes enabling efficient usage of water content in concrete.
- Delays initial hydration of cement resulting in delayed setting without adversely the strength gain.
- Reduction in water cement ratio improves early and ultimate strengths quiet significantly.
- Produces flowing concrete in pumpable consistency.
- Vastly improves workability of concrete in addition to retaining workability for working time.
- Improved Durability resulting from production of low permeability concrete.
- Reduces heat generation due to hydration even when used with high strength cements.
- Controlled retardation increases working life of concrete to ease construction and prevents formation of cold joints in large volume concreting.
- Free of chlorides, can be used in pre-stressed and reinforced cement concrete.
USAGE
- Ideally suited for high volume concreting projects.
- Suited for Ready Mix Concrete plants where concrete is to be transported.
- Slump retention property makes it ideal admixture for continuous concreting without formation of concrete cold joints.
- Ideal for production of high strength concrete of improved durability.
- Excellent compaction can be achieved in areas with congested reinforcement.
- Results in production of neatly finished concrete on removal of forms.
DIRECTIONS FOR USE
The generally recommended dosage for TecR Mix 240 is 0.3% to 1% by weight of cement. It is advised that site trials be conducted to optimize the dosage. Dosages outside the above range may be used in specific cases after site trials. Techny Tech Team will be able to guide you for such trials. TecR Mix 240 should be thoroughly stirred before use. The required quantity of TecR Mix 240 should be added to the gauging water and stirred to obtain uniform consistency before being added to the concrete mix.
