Superplasticizer

1. Properties:
Appearance: Dark brown powder or liquid>Non-poisonous, odorles, non-flammable and non-corrosive to steelbars. 2\As a condition of blending in which amount of cement and collapsibility are fixed aforehand, mixing water xan be decreased by 8-25% when it is admixed at 0.3-1.5% with reinforced concrete. Compression stength is in creased rapidl. Statistically, commpression strength on the 28th day after single application is increased by more than 20% when it is added at standard blend dosage. As the result, the seting properties of concrete will be improved to some extent. 3\Improve miscibility of concrete amalgamator with water and collapsibility as well. As a condition of equivalent blending (I. E. Water-cement ratio and amount of cement fixed), collapsibility can be increased by 12cm when it is added at standard blend dosage. 4\As a condition of blending which is preconditioned by equivalent collapsibility and strength, 12%of cement can by reserved when the agent is added at blend dosage. 5\The agent gives less crystallization in winter and surrenders smaller discounts of collapsibility in summer for seasnal reasons. Remarkable improvements of miscibility are shown when it is adminxed at low blend ratio. Hence, flowability of net slurry is in a slight shade. Water reduction of sand slurry is more critical for quality control than any other parameter. It can be concluded that it is suitable for large ratio and low-dose preparation.

3. Applications:
1\Widely used in pre-cast & ready-mixed concrete, armored concrete and pre-stressed reinforeed concrete in construction projects such as dam and port construction, road building& town planning projects and dwelling place erection ete. 2\Suitable for the preparation of normal, high-strength, superplastic, pumpable, flowwable & auto-flowable concrete. 3\Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolanic cement etc.

4. Packing&storage:
For powder: Woven bag with plastic liner. Net weight: 25kg 0.13or 50kg 0.25For liquid: Sealed plastic drums to prevent accidental leakage and evaporation. The material can be delivered or transported by tank car. 2\Cautions should be taken to prevent from being torn by sharp-ended objects while packages are transferred or delivered. When being contaminated by high humidity or moisture in case of leakage, it can be prepared in prescribed ways for further use without surrendering any effect.
