BT-303 is the latest innovation in slump-preserving polycarboxylic acid water reducers, meticulously crafted by Shandong Gaoqiang New Material Technology Co., Ltd. This cutting-edge formulation excels at significantly curbing concrete slump loss. Perfectly engineered for high-performance water-reducing applications, it finds its ideal use in pumping concrete, ultra-fluid self-compacting, high-strength and high-performance concrete, as well as commercial concrete.
This product's advanced molecular structure incorporates active groups such as ester and amide groups, resulting in a polycarboxylic acid superplasticizer with exceptional slump retention abilities. In the alkaline environment of concrete, ester groups gradually hydrolyze into carboxylic acid groups that adhere to the cement particle surfaces, providing a remarkable slow-release protection against slump loss.
In the alkaline setting of concrete, the reactive groups within this product's molecular structure slowly unleash dispersing groups that efficiently continue to separate the cement particles, thereby achieving an outstanding inhibition of concrete slump loss.
(1) Remarkable slump retention: Maintains over 80% of the fresh concrete slump after one hour, effectively addressing the challenge of rapid slump loss. This ensures continued workability and performance excellence.
(2) Superior post-application performance: Ensures fresh concrete with exceptional workability along with outstanding hardening and long-term durability.
(3) Versatile adaptability: Compatible with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and various admixtures.
(4) Eco-friendly production: Manufactured through a green, environmentally responsible process that produces no three waste products.

(1) Ideal for early-strength, retarded, precast, cast-in-place, large flow, self-compacting, mass, high-performance, and fair-faced concrete types, including ready-mixed and cast-in-situ concrete. Particularly advantageous for low-grade commercial concrete.
(2) Extensively applicable to significant national and key projects, including high-speed railways, nuclear power plants, water governance projects, hydropower endeavors, subways, large bridges, expressways, harbors, and wharfs.
(3) Perfect for diverse industrial, civil construction, and commercial concrete mixing plants.
1. Standard dosage ranges from 0.6% to 1.2% (based on the total cementitious material amount). Optimal dosage should be determined through experimental assessment, tailored to specific engineering materials and characteristics. Use alone or in combination with high water-reducing polycarboxylic acid water-reducing agents.
2. This product can be used independently or synergized with water-reducing mother liquor and set-retarding mother liquor to mitigate concrete slump loss. Alternatively, combine with functional aids to create admixtures with retarding, early strength, antifreeze, or pumping functions. Application methods and conditions should be established through thorough testing and compounding technology.
3. Suitable for use with other admixtures including early strength agents, air-entraining agents, and retarders, contingent upon pre-use testing. Avoid mixing with naphthalene series water reducers.
4. For concrete compositions containing active admixtures such as fly ash and slag, calculate the water-reducing agent amount based on total cementitious materials.
Package options include 220 kg drums, 23.5 tons per Flexitank, 1100 kg IBCs, or customized per request.
Storage: Safeguard your product by storing it in a well-ventilated, dry warehouse with a temperature range of 2-35 degrees Celsius. Ensure the packaging remains intact, without unsealing, granting it a shelf life of one year. Shield the product from direct sunlight and the risk of freezing to maintain its premium quality.
BT-303: A cutting-edge generation of slump-preserving polycarboxylic acid water reducer uniquely developed by our company, BT-303 is engineered to dramatically curb concrete slump loss while ensuring high water reduction. Perfect for applications in pumping concrete, super-fluid self-compacting, and high-strength, high-performance, and commercial concrete.
In alkaline conditions, reactive groups within the product's molecular structure gradually release dispersing agents, facilitating continuous cement dispersion and effectively preventing concrete slump loss.
(1) Outstanding Slump Retention: Remarkably, the slump retention value exceeds 80% of fresh concrete's initial slump after an hour, efficiently mitigating rapid slump loss. This capability effectively tackles the challenge of swift concrete slump loss, ensuring superior performance.
(2) Superior Performance: Upon application, the fresh concrete boasts excellent workability, enhanced hardening characteristics, and robust durability for lasting outcomes.
(3) Versatile Adaptability: Exhibits exceptional compatibility with Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and an array of admixtures.
(4) Eco-Friendly: Our production process is green and environmentally sound, generating no waste products.
