CSA Leak-stopping Agent

CSA Leak-stopping Agent

Introduction

CSA High Efficiency Water-stopping Agent is based on calcium sulphoaluminate cement, mixed with relevant additives in appropriate proportion, the feature of which is setting and hardening quickly with high strength,  high adherence while easy to use.

Properties

1. Rapid setting and hardening, short interval between initial and final setting. Under 20℃, the initial setting time is 3-5min, the final time is 1 min after initial.
2. Quick water stopping.
3. Slight expansion, good capability of anti-penetration. Paste curing in water after 3 days, no penetration under 1.5Mpa.
4. Excellent anti-sulfates and anticorrosion with durability
5. High erosion-resistance ability to sulfate and seawater(anti-sulfate coefficient>1), excellent durability，suitable for the anti-erodent and seawater projects
6. Strong adherence. Easy to adhere with the working substrate, can be worked in watery environment.
7. Easily used. Only mix with water while used.
8. Environmental product without toxin, smelling, pollution and radioactivity.

Application area

To be Used in the urgent leaking or penetration stoppage and repairs in different kinds structure of concrete, mortar or bricks, suitable for water-proofing and anti-penetration in underground engineering, water sluicing and piping, sewage farming system, kitchens and toilets.

Application Method

1. Before using, cut the leaking point or seam into the shape of bell mouthing or wedge, clear away the scraps and prepare suitable tools and measuring instruments.
2. Put 1kg of the water-stopping agent into the pot, adding 0.30kg of water and mixed quickly. Warm water should be used if the temperature is too low.
3. Knead the thick fluid to wet agglomerate by hands. When it become warm (about 3-5minutes), quickly press it against the direction of leaking, until the thick fluid is hardened (about 2-3minutes).

Storage

1. Packed with poly bags, 10kg/bag. Store in a dry and cool place.
 2. Once opened, use up. If not, seal the rest quickly.

CSA cement ( CSA binder )

Introduction General characteristics CSA Cement, also named Calcium Sulpho Aluminate Cement with grade: 42.5, 52.5, 62.5, 72.5, 82.5, 92.5, is a hydraulic binder based on calcium sulpho aluminate, rather than calcium aluminates which are the basis of Calcium Aluminates Cement or calcium silicates which are the basis of Portland Cement. It can be used on its own (with a Lithium accelerator), or with an Anhydrite, Portland cement mix, Metakaolin or a combination of all. CSA Cement has the benefit of being readily adaptable to suit many different applications where both rapid set and / or high early strength gain are required. It yields controlled set, enhanced early strengths, shrinkage compensation or expansion and sulphate resistance. Uses include any cement-based product in need of these properties. CSA Cement products exhibit a range of properties to suit a wide spectrum of cement-based applications, like fast setting cements, self-leveling or self-smoothing compounds, sel

Specialty cement technology-Rapid set CSA cement, High performance of concrete and mortars

Image
CSA cement, full name is Calcium Sulfoaluminate cement, was invented and developed in China since 1970's. It is 100% cement, get ready to use. As the third generation of cements, it is widely used on construction for decades in China. The cement has been used on concrete for bridges, airports, concrete road repair, winter construction and many other applications where early strength and time needed.As well as high strength concrete, high performance of mortars, like Self levelling compounds,tile adhesives,Non shrinkage grouts,etc. The product obtained by grinding cement clinker obtained by roasting suitable raw material, consisting essentially of anhydrous calcium sulphoaluminate and dicalcium silicate. Suitable gypsum and 0-10% limestone shall be blended with clinker during manufacture of rapid-hardening sulphoaluminate cement. The rapid-hardening cement product is hydraulicity binding material. It has high early strength. The code no is R-SAC. Specific surface are
