This product is non-toxin and non-flammable. MSDS is avaliable
APPLICATION
1.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.
2.Suitable for preparation of early-strength, high-strength, high-anti-filtration and self-sealing& pumpable concrete.
3.Used far and wide 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..
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 10-30% when it is admixed with reinforced concrete at 0.3-1.5%. Statistically, compression strength on the lst day ,the 3rd day and the 28th day after single application is increased by 70-100,50-80% and 25-50% 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.
3.Improve miscibility of concrete amalgamator with water and collapsibility as well. As a condition of equivalent blending ,collapsibility can be increased by 12cm when it is added at standard blend dosage.
4.12% of cement can be reserved when the agent is blended at standard blend dosage, which is preconditioned by same collapsibility and strength.
PARAMETERS& ACCEPTANCE CRITERIA（FOR REFERENCE）
RECOMMENDED BLEND DOSAGE
The blend dosage normally ranges from 2 %to 1.0% for variations of concrete grades and application fields. The optimal blend dosage for powder is 0.5%.
DIRECTIONS
1.Prepare solutions as required.
2.Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio:60%).
3.The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds
