| General Description |
The dynamics of cement hydration generates high temperature that affects the rate of hardening and ultimately the placing, finishing and compressive strength of concrete. At high temperatures, concrete hardens rapidly and placing and finishing is adversely affected. The addition of REAL SET 230 is to offset the accelerating and damaging effects of rapid hardening concrete. REAL SET 230 delays and controls the setting time of concrete through hydration control of the tri-calcium silicate phase of cement. The retardation effect extends the plastic characteristics of concrete for enhanced workability and economy in placement.
REAL SET 230 is formulated from a selected highly purified lignosulphonate and it does not contain calcium chloride. |

| Recommended Dosage |
REAL SET 230 is recommended at a typical dosage rate 300ml +- 50ml per 100kg of cement for most concrete mixes containing average concrete ingredients. The dosage rate can be modified to fit variations in cement, aggregate or job conditions or where special performance characteristics are required.
REAL POINT SDN BHD recommends that special mix designs with dosage rates outside recommended rate, be developed in consultation with our representative to achieve specified requirements. |
|
Effects of
Overdosing |
An overdose of double the recommended rate of REAL SET 230 will result in significant retardation. When overdosing occurs, it is important to maintain adequate curing so that the ultimate strength of the concrete will not be adversely affected but will increase ultimately. |
|
