APPLICATION

1. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stage of application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak-heat summer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed.

2. Suitable for preparation of early-strength, high-strength, high-anti-filtration and self-sealing& pumpable concrete.

3. Widely used in pre-cast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town planning projects and dwelling erections etc.

4. Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolanic cement etc.

PROPERTIES, FEATURES & CHARACTERISTICS
1.Appearance: Light brown powder& dark brown liquid. Non-poisonous, odorless, non-flammable and non-corrosive to steel bars.
2. Remarkable Plasticity: As a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 18-28% when it is admixed with reinforced concrete at 0.5-1.0%. Statistically, compression strength on the lst day, the 3 rd day and the 28 th day after single application is increased by 60-90% and 25-60% respectively when it is added at standard blend dosage. As the result, compression strength, tensile strength, buckling strength and modulus of elasticity will be improved to some extent.

PARAMETERS & ACCEPTANCE CRITERIA

USAGE:

1. Blending dosage at 0.5%-1.5%, 0.75% mixing dosage advised.

2. Prepare solutions as required.

3. Direct use of powder agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio:60%).
