ASD-9 Polycarboxylic Superplasticizer
Product introduction:
ASD-9 is a new polycarboxylate high-performance water reducing agent developed by our factory. It is suitable for all kinds of ready mixed concrete. Compared with common water reducing agents, ASD-9 has the advantages of high water reducing rate, low dosage, low slump loss, non toxicity and no pollution. It is the preferred material for preparing high-performance concrete with low cement dosage, good workability, good physical and mechanical properties and good durability. It can be widely used in ready mixed pumping concrete, high-grade ready mixed concrete, mass concrete, high fluidity self compacting concrete with dense reinforcement or parts not easy to vibrate.
Technical performance:
1. The product is a light brown transparent liquid, alkaline, low content of sodium sulfate, almost no chlorine salt, non-toxic and corrosive. The product has no sediment, and the density is 1.060 ± 0.020g/ml.
2. The degree of freedom in molecular structure is large, there are many controllable parameters in additive manufacturing technology, and there is great potential for high-performance.
3. The water reduction rate of concrete is more than 25%, which can save more than 15% of cement. Especially when the content of fly ash and slag powder is large, the economic effect is more obvious.
4. This product is a non-ionic water reducer with good adaptability to various types of cement. When it is used for pumping concrete construction, the slump loss within 2 hours is less than 60mm.
5. With high plasticity, high-quality flow plasticized concrete with good pumpability can be obtained.
6. High performance concrete with high strength (C60-C80), high elastic modulus, high impermeability, low shrinkage, low creep and good durability can be obtained by using this product.
Usage and precautions:
1. Recommended dosage: the dosage range of this product is 0.5-1.2%.
2. According to the concrete requirements, the mixing amount shall be determined after the test.
3. When preparing high-strength concrete, pay attention to the quality and material sequence of mixing and mechanical equipment.
4. This product shall not be mixed with other types of admixtures. Pay attention to cleaning the storage tank when replacing admixtures.
5. When changing cement varieties, necessary concrete trial mixing shall be carried out to confirm the adaptability of cement, so as to obtain the best use effect.
Packaging and storage:
1. This product is 200kg/iron bucket or 1000kg plastic bucket. If special specification packaging is required, it can be customized in advance.
2. It shall be covered for storage to avoid sunshine, rain and freezing.
3. The shelf life of this product is 6 months. It can only be used after passing the inspection.
