LY-PC is a new generation super- plasticizer based on polycarboxylate technology. This product is designed to provide medium to high water reduction, while providing excellent flowability during placement, and excellent slump retention without affecting initial setting time. This product incorporates the latest state of the art technology in high performance concrete. This product was designed to produce super high-strength, flowable and self-consolidating concrete in a variety of applications.
LY-PC meets the requirements of concrete admixture ASTM C494.

Benefits and Application
1、 High early strength and 28 day’s strength increase obviously, specially for high dosage fly ash concrete.
2、 Low slump loss, meets pumping aids standard.
3、 High durability, excellent workability.
4、 High water reducing rate, when slump is about 80mm，the water reducing rate reaches above 25%, while slump is 180mm, then is up to 30%.
5、 Green product, this product don’t generate pollution in the production process, and meets the request of ISO 14000.
6、 This product is applied to high performance concrete, high strength concrete, flowable concrete, self-compacting concrete etc.
Package, Storage & Handling
1. For powder, Woven fabric bag with plastic liner. Net weight: 25kg +/- 0.25 kg.
2. Cautions should be taken to prevent from being torn by sharp-ended objects while packages are being transferred or delivered. When being contaminated by high humidity or moisturein case of leakage, it can be prepared in prescribed ways for further use without surrendering any effect.
3. It should be stored in a dedicated warehouse that is well-ventilated and dry. It remains effective in one year. After the expiration, date, it can be used again if testing results fall within the established range.
A trained representative is available to assist in the preparation of specifications, and the resoluiton of concrete problems in the field.
