|  Topic: Reply to Roof Concrete Strength
Dear Navneet Jharia & S L Gupta Sir
Thank you very much for your Kind & Useful Reply of regarding Roof Concrete Strength.
1)Main Rod Dia 10mm at 6" C/C with Cranking
2)Distributor Rod Dia 8mm at 8" C/C
3)Roof Beam Dia 12 mm -5 Nos with Center Cranked & Height 12" Including 5" Roof Slop.
4)So Roof Beam Height (12"-5") = 7"
5) It has 16' x 16' Hall. So Two way Slap were done with Concealed Beam of Dia 16 mm -4 Nos at Middle.
6)All above are verified by taking photos with Measurement by Measuring Tape.
7) But Regarding concrete Strength , I have doubt that it will come between M15 (15 N/mm^2) to M10 (10 N/mm^2) by Reducing Cement by Builder.
8) How to check concrete Strength any conventional method whether M15 (15 N/mm^2) or M10 (10 N/mm^2). Suppose If it is between M15 (15 N/mm^2) to M10 (10 N/mm^2) , what is the way to improve the concrete Strength above M15 (15 N/mm^2).
9) Can we increase concrete Strength by Inner Ceiling Plastering ratio of 1:3 by Two Layering (or) using Admixture like Dr Fixit etc.,
10) Because Inner Ceiling Plastering is not started yet.
11) Any Instrument is there to find whether it is M15 (15 N/mm^2) (or) M10 (10 N/mm^2)??
12) Also Weathering Proof is not started yet. Can we increase Ceiling Strength by doing some modification at Weathering Proof.
Waiting for Your kind Reply
Jahankumar
