What is the minimum strength class for bricks used in these panels?

The bricks must have a minimum average compressive strength of 7.5 N/mm² (Class 7.5) as per Clause 4.1.

What grade of concrete is specified for the precast joists and in-situ works?

A minimum grade of M15 is specified for both precast joists and any in-situ concrete used in the system (Clause 4.3).

Is load testing required for these panels?

Yes, Clause 7 specifies the procedure for load testing of panels to verify their strength and serviceability performance.

What is the minimum curing period for the prefabricated panels?

The panels should be water-cured for a minimum period of 14 days after casting (Clause 6.1.5).

Practical Notes

This system is particularly effective for reducing the need for extensive shuttering, leading to faster and more economical construction, especially in low-rise buildings.

Strict quality control during the casting of panels is crucial, paying close attention to brick quality, mortar joints within the panel, and correct placement of reinforcement.

Careful handling, transportation, and erection of the prefabricated panels are essential to prevent damage before and during installation.
