Complex additive for reinforced concrete HEMIX HS

Additive description

HEMIX HS is a superplasticizer, stabilizer, strength gain gas pedal and water reducer, increasing frost resistance and water resistance of products. In terms of consumer properties HEMIX HS meets the requirements of GOST 24211-2008 "Additives for concrete and mortars. General technical conditions".

Field of application

HEMIX HS is a universal additive designed for the manufacture of reinforced concrete products and structures with high performance characteristics in the conditions of factory production.

It is suitable for use with cements containing pozzolanic additive.

Advantages

The use of HEMIX HS, at rather low flow rates, allows:

• to obtain mixtures with specified parameters at lower water-cement ratio;
• to increase the early demolding strength at TWO and in natural conditions;
• to accelerate the early strength gain;
• to improve the quality of the concrete face;
• to increase the turnover of molds;
• to reduce energy consumption at TWO;
• to increase the resistance to delamination.

Air entrainment of concrete with the admixture is 2.3-4.4%.

Mechanism of action

HEMIX HS molecules adsorb and promote rapid dispersion of cement particles due to electrostatic and steric repulsion forces. The additive accelerates the hydration of the cement.

At the same time, the contact surface of cement particles with water increases. This results in early heat release, accelerated formation of hydration products and, as a consequence, rapid strength development during the initial curing period. This advantage can be utilized by lowering the temperature and time of HWO.

There are no chloride ions in the composition, so the additive does not cause corrosion of reinforcement.

Dosage

HEMIX HS should be added in quantities of 0.65-1.45% of the cement weight. The exact dosage depends on the concrete requirements and is calculated under laboratory conditions.

Application

• Mix the admixture before use.
• Introduce HEMIX HS into the concrete mix together with the first or the last third of the water required for mixing.
• Allow sufficient mixing time after adding the admixture.

Important: HEMIX HS must not be added to dry mix.
