ZK-4B混凝土膨胀剂是我公司生产的低碱、低掺量，硫铝酸钙类高性能混凝土膨胀剂。其性能稳定，颗粒级配合理，膨胀性能的发展与转标后的水泥水化体系匹配。在混凝土中掺加8%~10%的该膨胀剂，可补偿混凝土的收缩，提高混凝土的抗渗抗裂能力。ZK-4B混凝土膨胀剂执行«混凝土膨胀剂»(GB23439-2009)标准，限制膨胀率符合Ⅰ型标准要求。

ZK-4B concrete expansive agent is a kind of low alkali,low content,calcium aluminate high performance concrete expansion agent.Its performance is stable,the particle size distribution is reasonable,the development of the expansion property match the cement hydration system.Concrete expansion admixture can compensate concrete shrink-age so that the concrete structure can resist crack and penetration efficiently.ZK-4B concrete expons1on agent to perform the‘concrete expansion agent'(GB23439-2009) standards,the expansion rate is in line with typeⅠstandard requirements.


主要技术性能
The main technical performance

1、本品为粉剂，无毒、无味、不燃，不含氯盐，对钢筋无锈蚀作用。

2、以推荐掺量掺入混凝土中，对新拌混凝土性能无明显影响。

3、内掺8%的ZK-4B混凝土膨胀剂，胶砂水中限制膨胀率达到0.040%，各项指标满足«混凝土膨胀剂»GB23439-2009的要求。

4、以8~10%的掺量等量取代混凝土中的胶凝材料，可在混凝土中产生微膨胀，减少混凝土的收缩。当配筋率0.2~1.0%时，混凝土限制膨胀率为0.020~0.040%，在混凝土中建立0.2~0.7MPa的自应力，从而补偿混凝土早期水化热引起的温度收缩和干燥收缩，提高混凝土的抗渗抗裂性能。

5、掺加适量的膨胀剂，能满足抗渗等级P8以上大多数混凝土抗渗要求。

6、掺加该膨胀剂的混凝土可大大提高抗硫酸盐侵蚀能力和海水侵蚀能力 。

1.This product is a powder,non-toxic,tasteless,non flammable,non chlorine salt,non-corrosive effect for steel.

2.In the concrete,the performance of the new mixed concrete has no significant effect.

3.With 8% ZK-4B concrete expansion agent,the swelling ratio of the gel sand water reached 0.040%. ZK-4B concrete expansion agent to perform the‘concrete expansion agent'(GB23439-2009) standards.

4.Replace the cementitious materials in concrete with 8 to 10% of the volume equivalent,can produce micro expansion in concrete,reduce the shrinkage of concrete.When the reinforcement ratio of 0.2 to 1.0%,the concrete limited expansion ratio of 0.020~ 0.040% in the concrete establishment of 0.2 ~ 0.7 MPa self stress,to compensate the concrete early hydration heat caused by temperature shrinkage and dry shrinkage,improve the concrete impermeability crack resistance.

5.Adding the expansion agent,it can meet to reqairements of most of the concrete anti permeability level P8.

6.Adding the expansive agent can greatly improve the resistance to sulfate attack and seawater erosion.


注意事项
Notes

1、本品在使用时，等量取代混凝土中的胶凝材料，推荐掺量8~10%；配置后浇缝、后浇加强带混凝土需提高掺量。

2、现拌工地或搅拌站必须按确定的补偿收缩混疑土配合比投料，计量装置必须准确，膨胀剂不能少掺，否则达不到补偿收缩的要求，但也不能超量掺加，否则将对混凝土结构产生破坏作用。

3、掺加膨胀剂的混凝土搅拌时间要比普通混凝土延长30S，浇筑时，混凝土振捣要均匀密实，不漏震、不欠震、不过震。

4、掺加膨胀剂的混凝土养护非常重要，应及时浇水养护，使混凝土表面始终保持湿润状态，养护期不少于14天；负温施工要保证混凝土入模温度不低于5℃，浇筑后要立即用塑料薄膜和保温材料进行保温保湿养护。

1. When use this product,the equivalent replacement of the contentious materials in concrete,recommended dosage of 8 ~ 10%;The mixing amount should be increased after the preparation of the cast.

2.The site or mixing station must be in accordance with the determination of the compensation shrinkage of concrete,Metering device must be accurate,the expansion agent can not be less mixed,otherwise,it is meet the requirements of the compensation contract.However not excessive adding,otherwise it will cause damage to concrete structure.

3.The mixing time of concrete mixed with expansive agent is longer than that of ordinary concrete 30s.When pouring,Concrete vibration should be uniform and dense,not leak,not under earthquake.

4.Admixture of concrete curing is very important.should pnomptil watering consenwation.Make the concrete surface always keep moist condition,the maintenance period is not less than14days,Minus temperature construction to ensure that the concrete into the mold temperature is not less than5 degrees Celsius,and immediately after the placement of plastic film and thermal insulation materials for thermal insulation.
