Concrete setting acceleration
ADINOL-RAPID Broad-use concrete set accelerator – Antifreezing agent
I. NATURE OF THE PROBLEM – REQUIREMENTS
In cases where fast curing and thus achieving high early strengths is essential (anchoring, repairs, etc.), or concrete placing in low temperatures, an accelerating admixture must be used.
ADINOL-RAPID is used for accelerating the setting time of concrete. Certified with the CE marking as concrete set accelerating admixture according to EN 934- 2:T6, certificate number: 0906-CPD- 02412007. It allows concrete placing in low temperatures up to -10 °C. ADINOL-RAPID is not an air-entraining agent, is free of chlorides and other corrosive substances and is suitable to use with all kinds of Portland cements.
Dosage: 1,0-2,0% by weight of cement, depending on the desired reduction of setting time.
ADINOL-RAPID can be added:
- Into the mixing water, during the preparation of concrete.
- Into the ready concrete mix just before placing. In that case, it is necessary to rotate the mixer for 4-5 minutes to achieve uniform dispersion of ADINOL-RAPID in the mix.
- Avoid concrete placing when temperatures lower than -100C are expected in the next 12 hours
- Excessive dosage may decrease final strength of the concrete.
