Rain fall on RCC (Reinforced Cement Concrete) slab
Rain fall on RCC (Reinforced Cement Concrete) slab
(OP)
Hi,
This question is for a temple construction in Gujarat Province of India. My brother is managing one project of temple construction there.
He just finished a RCC (Reinforced Cement Concrete) slab and just after casting a slab a heavy rain fall on slab for about half an hour. Can you please advise what remedial measure can be taken now?
How we can save this slab? What kind of damage may occur?
Waiting for your earliest reply.
Thanks,
Atul

1. The durability of the slab now is in question.
2. The concrete will not be able to achieve its design strength.
3. The rainfall must have created open path in the concrete where the rain water seeped thru the slab. This only means the slab is now porous.
4. The reinforcement will rust out pretty quickly.
As a remedy, you probaly can remove the slab and start over. Next time try to keep it covered.

1. Knowing how deep the damage goes (cores and applicable material analysis...expensive)
2. The availability of local contractors to grind the slab...have they the right equipment to do it right without damaging the lower layers.
3. The availability of bonding agents to use.
4. The function of the slab - if it is just for an interior living space, perhaps ok to do this. If it is for a high performance warehouse slab with forklift traffic, etc., then maybe the bonded topping wouldn't be a good idea.
