Product Q&A
Q:What causes black stains on concrete?
A:
Black stains are caused by unburned carbon particles in cement, fly ash, or other raw materials that migrate to the surface during hydration.
Q:How should the dosage be determined?
A:
Dosage depends on carbon content and stain severity; start with 0.1%-0.3% for slight risks and 0.3%-1.0% for severe risks.
Q:Can this product be blended with superplasticizers?
A:
Yes, it can be pre-blended into liquid polycarboxylate superplasticizers at a ratio of 1.5% to 20% by weight.
Q:Does BS-1 affect concrete strength or setting time?
A:
No, it has no negative influence on concrete compressive strength, setting time, or workability.
Q:What is the minimum order quantity?
A:
The minimum order quantity is 25 kilograms.
