BT-302 is a new generation of fast-releasing and slump retaining mother liquor made from TPEG by free radical polymerization, and a new sustained-release group is introduced into the synthesis. Under the alkaline condition of concrete, the slow-releasing group in the molecular structure of this product can slowly release the group with dispersive function, playing the role of continuing to disperse the cement, so as to achieve the role of inhibiting the concrete slump loss. It has a low water reduction rate, but it has very high slump protection performance. Generally used with water reducing mother liquor, It is mainly used in high-strength concrete with higher requirements for slump protection performance, and its products are widely used in pumping concrete, super-flow self-compacting and high-strength high-performance concrete and commercial concrete for high-speed railway, expressway, hydro-power and other large engineering projects.

1. Applicable to the configuration of early strength concrete, retarded concrete, precast concrete, cast-in-place concrete, flow concrete, self-compacting concrete, mass concrete, high-performance concrete and clear concrete, especially for low-grade commercial concrete.
2. Widely used in high-speed railways, nuclear power, water conservancy projects, subways, large bridges, and expressways.
3. Applicable to all kinds of industrial and civil construction and commercial concrete mixing stations.
1. Dosage: Usually use 0-30% mother liquor with reducing water mother liquor. The dosage of water-reducing agent is generally 1% ~ 3% of the total weight of cementing materials.
2. Adaptability: Before use or changing cement/gravel batches, carry out adaptability tests to formulate the correct proportion.
3. Compounding: Can be combined with set retarding mother liquor or functional aids (retarder, early strength, antifreeze) to craft specific admixtures.
4. Compatibility: Can be integrated with early strength agents and air entrainment agents. Do not mix with naphthalene series water reducers.
5. Mixing: Ensure measured water is added simultaneously to the mixer. Calculation should be based on total cementing materials including fly ash and slag.
Packaging: Available in 200kg drums, 1000kg IBC containers, or customized.
Storage: Well-ventilated, dry warehouse at 2-35ºC. Shelf life is one year. Safeguard against direct sunlight and freezing.
Refer to the Material Safety Data Sheet for comprehensive details. This serves as a reference; preliminary tests are always recommended to verify product applicability.
