（三） F - 511 (B) the concrete waterproofing helps
the medicinal preparation/chemical additive
F－511(B)型混凝土防水助剂/添加剂
Ingredient/outward appearance:
American silicon membrane organic silicon hydride/transparent liquid
Product characteristic:
This product is the concrete water-resisting admixture, mainly is suitable for the enhancement, Resistance seepage, anti- frozen, the anti- crack, bears the acid and alkali and the durability high requests high strength Concrete, Pumps Delivers Concrete, the great volume Concrete, the fluid state Concrete, from to be dense Concrete, the water conservancy project Concrete, the underground waterproofing Concrete, each kind of intrinsic structure from waterproofing Concrete and waterproof concrete project. Can effectively suppress the base material seep, get damp, prevents the concrete reinforcement because to seep rusts causes the dehiscence which the inflation produces. But effectively makes up the base material tiny crack also it has the permeability. Maintenance base material original outward appearance.
Carrelation index:
1. Mixes the water-repellent the concrete, various ages time intensity enhances 20% ~ about 35%.
2. Resistance seepage the target and the datum sample compare may enhance 2 time of ~ 3 times.
3. Has compensates the concrete shrinkage function, compensating rate approximately for (2 ~3.5) ×10-4.
4. Under Water& Ash Proportion the same condition, the concrete Caves in only increases > 10cm, concrete Caves in 2h retains > 12cm; In the concrete Caves in invariable situation, reduces Shui Lvke to reach 10% ~ 14%; In with under the datum sample maintenance uniform strength premise, may save cement 6% ~ 10%.
5. The concrete Caves in and Caves in loses and the set time may act according to the temperature and the construction request, through mixes the quantity to come suitably to mix.
6. May delay the concrete heat-release rate.
Application method:
Each cubic meter concrete calculates roughly the use water-repellent 3-4 kilogram original fluid.
成分/外观：
美国硅膜**硅烷/透明液体
产品特点：
本产品为混凝土防水外加剂，主要适用于增强、抗渗、抗冻、抗裂、耐酸碱及耐久性要求较高的高强度砼、泵送砼、大体积砼、流态砼、自密实砼、水工砼、地下防水砼，各种内在结构自防水砼及防水混凝土工程。能有效抑制基材渗水、返潮，防止混凝土钢筋因渗水生锈而引起膨胀所产生的开裂。可有效弥补基材细小的裂缝且其具有透气性。保持基材原有外观。
相关指数：
1.掺防水剂的混凝土，各龄期的强度提高20％～35％左右。
2.抗渗指标与基准样品相比可提高2倍～3倍。
3.具有补偿混凝土收缩功能，补偿率约为(2～3.5)×10-4。
4.在水灰比相同的条件下，混凝土坍落度净增＞10cm，混凝土坍落度2h保留＞12cm；在混凝土坍落度不变的情况下，减水率可达10％～14％；在与基准样品保持等强度的前提下，可节省水泥6％～10％。
5.混凝土的坍落度和坍落度损失及凝结时间可根据气温和施工要求，通过掺量来适当调配。
6.可延缓混凝土放热速率。
使用方法/注意事项：
每立方米混凝土用量等同于混凝土中水泥重量的0.5-0.7％ 。
