Frequently Asked Questions

What is the main advantage of polycarboxylate superplasticizers over naphthalene-based ones?

Polycarboxylate ethers (PCE) offer higher water reduction (up to 40%), better slump retention, lower dosage requirements, and improved compatibility with supplementary cementitious materials compared to traditional naphthalene sulfonate (SNF) admixtures.

Can sodium gluconate be used in high-strength concrete?

Yes, sodium gluconate acts as a retarder and plasticizer, making it ideal for high-strength and mass concrete applications where controlled setting time and reduced heat evolution are critical.

Do you offer custom formulation services?

Yes, our R&D team provides tailored admixture solutions based on specific raw materials, climate conditions, and performance requirements.

What certifications do your products have?

Our manufacturing facility holds ISO9001, CE, and ISO13485 certifications, ensuring compliance with international quality and safety standards.
