I post something sometime ago.. Can read up.

Initial poring if heavy rain, is not good and will also weaken. But if pour for some hours then only rain is ok (with proper cover)

If its just abit/normal rain thn ok? (for initial pouring) My contractors even told me its better if its rain, as the concrete wont crack so easily. Thx!

Mild rain or drizzling is ok... It helps in curing process.. This is very important especially using high grade concrete where cement content is high..

TS, fyi green ready mixed concrete not suppose to mix with water after it is inside the readymixed truck.

any additional water will make the cement loose strength...

if you using it for rc pillar or 2nd floor surface.. it might not be as strong as its suppose to be

Yes, you are right.

its okie to pour in the rain just dont let the rain make teh cement too wet..

best if you can set up a canopy to protect the area from rain..

or pour before it rains and cover it with those orange/blue layer of mat to keep it from kena-ing the rain water

Ok, ths guys!
