Precautions for Use
It must be used in accordance with the minimum cement dosage and maximum water-to-cement ratio specified in the standards.
The curing process must be performed in accordance with standards.
Formwork should not be removed before the concrete poured into it has achieved sufficient mechanical strength.
The long-distance transport of ready-mix concrete should be avoided.
Precautions should be taken to prevent cracking during concrete pouring in hot and windy weather.

Situations in Which Use Is Not Recommended
In applications where high whiteness is required, the desired level of whiteness may not be achieved if aggregates with an inappropriate color tone are used.
