High Performance Self levelling Material (concrete flooring mortar)-by using white Anti-cracking Fast setting Rapid hardening High Belite CSA cement

The Self levelling materials ( Concrete flooring mortar, self levelling compound, self levelling screed ) is the difficult part of mortars. Especially for overlayment. cracking issue is a big problem and exsist on concrete and mortars.

Triditional way of producing Self levelling material is based on Portland cement+High alumina cement/CSA cement (CA/CSA cement)+Gypsum. Cracking is hardly controlled. In recent years, we designed a new product called White Anti-Cracking Fast setting Rapid hardening High Belite CSA cement. The product can be 100% instead of "Portland cement+High alumina cement/CSA cement (CA/CSA cement)+Gypsum" Part. Free shrinkage rate is only 1/10-1/8 of Portland cement.



Physical Properties

Blaine (Fineness) ≥ 480 m2/kg

Initial Setting time: ≥ 15 mins Finial Setting time: ≤ 45 mins

28 days Free Expansion Rate （%） In water ≤ 0.08 In air ≥ -0.05

Whiteness ≥70

Grade 32.5

Compressive Strength 4hours ≥12.5Mpa 7days ≥32.5 Mpa 28 days≥40.0 Mpa

Flexural Strength 4 hours ≥4.0 Mpa 7days ≥ 5.0 Mpa 28days ≥6.0 Mpa



Advantages:

1. Fast setting, Rapid hardening, High strength, 4 hours compressive strength could reach 15 Mpa, more than 40 Mpa within 28 days

2. Micro expansion, Low dry shrinkage, the length change is very small. Dry shrinkage rate is just 1/10 of Portland cement

3. Excellent Anti-corrosion property in sulfate, chloride, magnesium salt and seawater. Corrosion resistance coefficient ＞1.

4.High impermeability, permeation height is 1/5 of Portland cement.

5. High frozen resistance property, it can get the strength of critical intensity of cold in 2h-3h.

6. Low hydration heat release.

7. PH value is around 10.0, low alkalinity, good for GRC products

8. Whiteness more than 70.

9. Whiskering resistance performance is good


10. Can be mixed with portland cement in a proper ratio, can greatly reduce the shrinkage of portland cement, reduce the cracks.



Applications:

GRC products, Decoration mortars, Interior and exterior walls, Indoor and outdoor floors, Cement based self levelling mortars, Artifical stone and floor, Thin layer of concrete repair and concrete levelling material, Anti cracking rending mortar, Exterior insulation rendering mortar, bonding mortar and tile adhesive, Decorative concrete, Prefabricated concrete, Building reinforcement, High early strength Non shrinkage grouts, Waterproof and plugging materials, etc.


Due to its white color and performance, highly recommend to use on concrete self levelling overlayement, thin layer of concrete levelling material, artificial cement floor, concrete surface repair mortars, etc.

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...

CSA cement ( Rapid set cement )

CSA cement is one type of cement has the advantages of super high early and final strength, low alkaline, fast setting time, rapid hardening, frost & corrosion resistance, etc. Due to its wonderful performance, it can be used in many applications like mining industry, bridge decks, airport runways, patching concrete roadways, sidewalks, pavements, etc. where rapid strength developments are necessary. CSA cements offer tremendous advantages over Portland cement in terms of strength, setting time, speed and greeness .It main features are high initial and final strength, concentrative hydrating heat release, fast setting time, good fluidity, high frost and corrosion resistance, impermeability, low carbon, etc. It can be used in the following areas: 1. High strength cement & concrete 2. Dry mortars, such as tile adhesive, high strength grouting materials, self-leveling materials, rapid setting mortars, etc. 3. Concrete repair materials, Pavement repairs and other repair...
