Product introduction
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.
Main Feature
*The slow-release mother liquor was faster release PCE mother liquor.
The release time is generally after 30min (according to the material that the release time is difference)
*With super high slump performance, can let the concrete slump 2h without loss
*Low water reduction rate is generally not used alone, it needs to be combined with water reduction mother liquor
*With low viscosity and thixotropy, it is more suitable for concrete with low water cement ratio

How to use
1. This product is a colorless or light yellow liquid. Dosage:Usually ,use 0-30% mother liquor with reducing water mother liquor, and mix other small materials to make water reducing agent. The dosage of water-reducing agent is generally 1% ~ 3% of the total weight of cementing materials.
2.Before use of this product or changing the type and batch of cement and gravel, it is necessary to carry out adaptability test with cement and gravel. According to the test, formulate the proportion of water reducing agent
3.This product can be single used(Usually it could not use in single) It can be combined with water-reducing mother liquor and set retarding Embrace innovation with our mother liquor, designed to effectively reduce concrete slump loss, ensuring optimal performance. Combine it seamlessly with functional aids to craft high-performance admixtures that boast exceptional retarder, early strength, antifreeze, and pumping capabilities. Experience the transformative potential ofour solutions. Unleash the full potential by determining the ideal application method and conditions through rigorous testing and advanced compounding technology to achieve unparalleled results.
4.This product harmonizes effortlessly with other admixtures such as early strength agents, air entrainment agents, and retarders. Conduct comprehensive testing prior to use to ensure compatibility. Avoid mixing with naphthalene series water reducers for optimal performance.
5.Concrete cement and mix ratios are best determined through meticulous testing. During use, ensure the admixture is combined with mixed and measured water or simultaneously added to the concrete mixer. Conduct thorough mixing tests in advance to guarantee the superior quality of the concreteproduced.
6.When employing active admixtures like fly ash and slag, ensure the water-reducing agent calculation is based on the total cementing materials for optimal integration and performance.
