SY-1D早强减水剂的介绍、配方、成分、性能、使用方法等.doc

SY-1D早强减水剂SY-1D早强减水剂由减水组份和早强组份复合而成本品掺量小，减水率高，早期强度提升迅速，不降低后期强度，可广泛的适用于工民建、公路、铁路、水工港口等工程的混凝土施工一、 产品特性外观：浅褐色或土黄色粉末水泥净浆流动度：160~260mm以上二、 主要技术性能指标及特点本品减水效果显著，按照GB8076-1997《混凝土外加剂》国家标准测定：最大减水率达30%，依掺量减水率可调范围10~30%减水率及坍落度要求越高，掺量越大，不泌水，不离析掺入本品可迅速提升混凝土的早期强度，同条件下，三天强度可达到设计强度的60%以上本品可大幅提高混凝土抗压强度比：1d提高80~200%、3d提高60~100%、7d提高30~80%、28d提高20%以上低标号水泥掺入本品后，效果更加显著本品不含氯盐，对钢筋无锈蚀作用，无毒，无刺激性和放射性，不污染环境三、 使用方法和施工注意事项推荐掺量：胶凝材料总量的1.5~3.0%(可等量替代水泥)粉剂直接与水泥一起投入搅拌机并延长搅拌时间30~60s本品适合于在常温及最低温度不低于-5℃环境下施工.四、 产品包装、运输、贮存包装：采用内衬塑料薄膜编织袋包装，规格：50±1kg/袋运输：可用汽车或火车运输，在运输过程中粉剂应注意防破损、防潮贮存：粉剂应放于通风、干燥处，注意防破损、防潮。

SY-1D Early Strength Water Reducing Admixture SY-1D Early strength Water Reducing Admixture is made of composite components of water- reducing and early strength components. The product has the properties of low dosage, high water- reducing rates; it can improve early strength quickly, while it does not reduce the later strength, which can be widely applied to industrial and civil engineering, highways, railways, hydraulic and Ports and other concrete construction projects. 1 Features1) Appearance: light brown or yellowish powder 2) Cement paste fluidity: 160 ~ 260mm or more. 2 the main technical performance and characteristics 1) The water-reducing effect of this product is remarkable; Determination is carried out According to the national standard "Concrete Admixtures GB8076-1997" : the maximum rate is up to 30% , water-reducing rate is adjusted by 10 ~ 30% as per dosage. The higher water reduction and slump required, the greater the dosage needed, without bleeding and segregation. 2) it can rapidly improve the early strength of concrete; Under the same condition, the strength at 3 days age shall reach60% of the design strength . This product can substantially increase the compressive strength of concrete: comparing to the design strength, 1d increase 80 ~ 200%, 3d increased 60 ~ 100%, 7d increase 30 ~ 80%, 28d increased by 20%. 3) It has more significant when it is used with low-grade cement; 4) This product has no chlorine salt, no corrosion effect on steel, non-toxic, non-irritating and radiation and it shall not pollute the environment. 3 Usage and precaution:1) Recommended dosage: 1.5 ~3.0% of total cementitious materials (it can be equivalent replacement of cement).2) The powder shall mix directly with cement and extend mixing time 30~60s3) This product is suitable for the construction under normal temperature ,and the lowest temperature shall not lower than-50C;4 Package, shipment and storage 1) Packaging: Plastic knitted sack with plastic membrane lining; 50±1kg per bag. 2) Shipment: by track or train, care must be taken to prevent damage, moisture during delivery3) Storage: The powder admixture shall be stored in dry and ventilation place. Be careful not to get damaged and moisture.4) Valid period: two years. 。
