CHEM 5000 PB is an aqueous solution of synthetic polymers ready for use. It complies with EN 934-2 Table 3.1, 3.2.

USE

CHEM 5000 PB is used:

• as superplasticizer for concrete during winter conditions, for precast concrete, floor slabs, foundations, gunite and other constructions,
• as water-reducing agent for precast elements, bridges etc., since accelerating hardening and setting of concrete.

ADVANTAGES

• For work in winter conditions down to -10°C.
• It does not affect the reinforcement or other building materials.
• It increases the concrete's strength and watertightness.
• It decreases the amount of vibrating.
• It ameliorates the adhesion of concrete on the reinforcing steel.
• It decreases cracking.

INSTRUCTIONS

CHEM 5000 PB is added to the concrete in the ready mix plant or locally at the job site. The duration of its effect is up to 1 hour at 20°C.

Dosage: For normal conditions from 0.4 to 3% on cement weight. The dosage depends on the temperature, the quantity and quality of cement, the W/C ratio, the desired final workability etc.

USEFUL DATA

Packaging: IBCs of 1300 kg, drums of 250 kg, containers of 20 kg.

Shelf life: At least 6 months in the original sealed containers at temperature over -15°C. If frozen, it can be defrosted at low temperature (30°C) under continuous stirring and used without problem.
