As general guide-lines the following items are important for successful execution of the concrete ground floor slab
The specification should give clear and precise requirement.
The floor shall be designed to carry specified loading with adequate factor of safety.
The selected contractor shall be experienced with good track records and with available resources to tackle the execution of the job.
Design, drawings and materials specified will be important. The type of concrete and the floor with
joints and isolation details or not to be defined clearly.
Study of sub-soil condition and water proofing requirement to be ensured.
Preparation of well compacted sub-grade and the built-up sub-base layers is important. The layer
underlying the concrete slab should have provision to reduce frictional resistance to concrete slab.
Shrinkage reducing admixture may be required.
The amount of fibres should be minimized to control water demand and cement content and
subsequently shrinkage.
Control on concrete mix design and proper supervision will be very important.
