Product Description
BT-302 Water Reducing & Retention Type
It is based on molecular designs and adsorption capacity of polycarboxylate,we do R&D and successfully produce water reducing and retention type polycarboxylate superplasticizer for concrete.With initiating systerm and reaction conditions,we achieve high adaptability of JS-103.
Main function: wide adapability of kinds of cements,gravels and sands. water reducing ratio and better retention,ability of solving slit content of sand and gravel.With it's stable performance,it's widely used in all kinds of concrete projects and cement product, that is well received at home and abroad.
·Homogeneity Index
Items | Enterprise Standard |
Apperance (23ºC) | Colourless to light yellow,viscous liquid |
PH Value (23ºC) | 6.5±1 |
Solid content (%) | 40±0.5 and 50±0.5 |
Content of Chloride (%) | ≤0.10 |
Water Reducing Ratio (%) | ≥28 |
·Scope of Application
BT-302 can be widely used in all kinds of concrete projects and cement product,for example:
1.Suitable for long-distance construction projects type pumping concrete.
2.Suitable for compounding normal concrete,high-performance concrete,high-strength concrete and ultra-high strength concrete.
3.Suitable for impervious,antifreezed and high durability concrete.
4.Suitable for high-performance and high flowing concrete,self-leveling concrete,fair-faced concrete and SCC(self compact concrete).
5.Suitable for high dosage of mineral powder type concrete.
6.Suitable for mass concrete that used in expressway,railway,bridge,tunnel,water conservancy projects,ports,wharf,underground etc..
·Usage
1. Recommended dosage ( by binding materials' weight) is 0.25%-0.60%( on the base of 40% solid content). The optimum dosage is according to the reality project conditions and actual materials.
2. Compatibility test should be done in advance when used with other additives.
3. Precise measurement avoids repeat dosage,seep dosage and errors.
·Storage and Safety Matters
1. BT-302 should be stored at temperature from 0ºC-40ºC. Keep out of sun,rain,impurity.Avoid evaporation of water.
2. Bt-302's quality guarantee period:180 days. Retest should be done when it beyond validity,and can be used when it's qualified.
3. Bt-302is non-toxic, non-polluting and non-edible. Avoid touching with eyes and skin allergy people. If touching,should clear with water and timely go to see doctor..
We could supply services as below:
technical support about concrete air content,polycarboxylate ether and ester difference,usage of other concrete admixtures in PCE, and also we could help you adjust the test redults of PCE with your raw materials data of concrete.
Development of concrete water reducing admixture:
the first generation water reducers are:lignosulfonate types(Na,Mg,Ca).
the second generation water reducers are:naphthalene sulfonate type,Sulfonated melamine formaldehyde type,aliphatic series,aminosulfonic acid series.
the third generation water reducer are :Polycarboxylate based superplasticizer.
Test Method 1 suggested:
Dosage of 50% PCE % | Ratio of Water reducing %(at least) |
0.03 | 28-30 |
0.35 | 28-30 |
0.4 | 32 |
0.45 | 32 |
0.5 | 32-40 |
0.6 | 35-40 |
Standard=1.2 g PCE + 87g Water + 300g Cement |
Weight of PCE Dosage=Dosage * (Weight of cement + fly ash + mineral )
Test Method 2 suggested:
10%PCE=10g 50% PCE +90g water
(10%PCE is 5 solid content = 50*10%)
Proportion of concrete:
Cement 450g
Sand 1350g
Water 160g
10% PCE 12g
(different countries have different size and stand of sand and gravel),when you do test,you can let us know the size of your concrete raw material.)
