Q-MAX™ Retarder
Overview
Q-MAX™ Retarder SG-100R is a highly efficient admixture which is a modified Polycarboxylic Ether (PCE) & Sodium Gluconate mix.
Uses
Q-MAX™ Retarder SG-100R is used as a retarding admixture in structural and mass concrete where a controlled extension of setting time is required, such as:
- Large volume pours
- Avoidance of cold joints
- Construction joints without formwork
- Long hauls
- Difficult placing conditions
- Elevated temperatures
Characteristics
- Controls extension of setting times
- Q-MAX™ Retarder SG-100R does not contain chlorides or other ingredients promoting corrosion of steel reinforcement. It is therefore suitable for reinforced concrete structures.

Recommended Dosage
0.3 – 3.0% by weight of cement (270 – 2,700 ml for 100 kg cement)
The retardation rate achieved is directly dependant on the dosage rate which in turn is influenced by the quality of cement, aggregates, w/b ratio, and temperatures.
Overdosing Effects
Dosages above the recommended limits may cause excessive retardation, but ultimate strengths aren’t affected negatively. During this period the concrete must be kept moist in order to prevent premature drying out.
