@@AfricaBuildingHub yes, very important. What about modern cement chemistry has changed so much compared to those used for old buildings which rarely had rising dampness. Also why modern cement doesn't scotch the hands. The old ones used to be strong.
Point of correction C30 concrete is equivalent to 32.5. C35 to C40 is equivalent to 42.5. it all depends on what conpressive strength of cement your structural engineer recommends for your building. C30 / 30mpa can be used for mass reinforced concrete as well. As long as you follow the curing guidelines. If youre not building a 10 or 15 floor building why waste money on the 42.5 /40 mpa cement. Maybe they're not using right mixtures and compressive strengths in Ghana Its Just a way to deter people from using the 32.5 R cement

I become excited when I see professional women engineers. Thanks for the info.
You are welcome and thanks bebree for watching!
Awww...I know this lady ...we went to the same Secondary school...St. Roses
Oh really? That's great!
Very very In formative!!
Thanks for sharing
Nice work. Very good explanation . Good work SupaCem
Thanks for the feedback. Watch out for the next part ☺️
Great step, keep it up Snr.
Thanks bebree
What size of plywood is good for Decking?
The rising damp issue, do they have an answer?
I will ask them in the next series!

We really needed that 10 year old explanation 😂
Hehehe
Meaning 32,2r should never be use for Concrete or block work
for dem everyday is a neverending slump test. now u know why is 120c per bag.
😂
explanation well define for our understanding....Fellow QS gather here lets like,share and subscribe to the channel
