Concrete setting accelerator Protex PT-9

The Protex PT-9 concrete setting accelerator accelerates setting and hardening, ensuring the mobility of the concrete mixture. Increases the density of finished products and water resistance.It is used for screeds, monolithic construction, masonry and other types of construction work at low and subzero temperatures from 5 ° C to -15 ° C.

Basic properties:

• to increase the early (by 20-40%) and grade (by 5-10%) resistance of concrete;
• increase the turnover of the threshold resistance;
• reduce heat treatment modes without reducing strength;
• reduce the water requirement of the concrete/soluble mixture;
• reduce cement consumption by 5-10%;
• allows you to work at temperatures up to -150 C

Dosage:The consumption of the additive is 0.8-14.5% of the cement weight by dry matter, 1.5 – 2.5 liters per 100 kg of cement.
