Jabale Rahmat Tower 💰 Financial aspects Inshallah, the potential cost to complete a flat: 55–57 lakhs (±) Current market price per square foot: 8,500 taka Sale price of 1 flat (current market): 1 crore 32 lakhs 60 thousand taka Future prospects: The possibility of further increase in market price within two and a half to three years is very bright. Natori Developers Assalamu Alaikum Today we will discuss in detail the chemical equation of hydration in the concrete series of Jabale Noor Flat Owners Society. It will be explained in simple language. Chemical equation of hydration Assalamu Alaikum wa Rahmatullah. Today we will look at the chemical equation behind concrete hydration. Knowing these, you will understand why water is so important and what happens if curing is not done. Main Compounds of Cement (0:45 - 2:00) Portland cement contains four main compounds: • C₃S — Tricalcium Silicate (most important) • C₂S — Dicalcium Silicate • C₃A — Tricalcium Aluminate • C₄AF — Tetracalcium Aluminoferrite Now let's see the reactions of water with them. 1. Hydration of Tricalcium Silicate (C₃S) (2:00 - 4:00) Most important reactions: 1. Jabale Noor Flat Owners Society Tower (Land area 13.5 Katha, B+G+13 floors, 6 units per floor, total 72 shareholders and additional 6 common, total 78 flats. Per flat net 1220 sq ft common B+G+ additional one flat, top roof, total 414 including car parking, total 1634 sq ft per flat. 3 bedrooms, 3 bathrooms, 3 balconies, drawing and dining room, 2 lifts, 2 stairs, 4 toilets, 2 roads in front and back 30 feet in front and 16 feet in back) 2 shares will be sold in the ongoing project, the price of which is 22 lakh taka. Address Dhanmondi River View Model Town Society Avenue Road adjacent. Simply: C₃S + H₂O → C-S-H (gel) + Ca(OH)₂ (lime) • This C-S-H gel is what gives the concrete its strength and adhesion. • Most of the strength comes from this reaction in the first 7 days. Simply: C₂S + H₂O → C-S-H + Ca(OH)₂ • It happens slowly, so strength continues to increase until 28 days. 3. Hydration of tricalcium aluminate (C₃A) (5:30 - 7:00) (It happens very fast and generates a lot of heat) 4. Hydration of C₄AF This happens slowly and is responsible for the color of the concrete. Summary equation (simple version) (7:00 - 8:30) Simply put: C-S-H gel = “glue” of the concrete Ca(OH)₂ = keeps the concrete alkaline, which protects the rods from rusting. Important Information (8:30 - 10:00) • Hydration is an exothermic reaction (heat is generated) • The reaction stops in the absence of water • Hydration is completely completed with proper curing • As a result, the concrete gets full strength and cracks are reduced Outro (10:00 - 11:00) Alhamdulillah, in the Jabal Noor project, we are not just pouring concrete, we are doing strong work by following the correct chemical process. Your flat will be safe for a long time, InshaAllah, because of this scientific method. If you like the video, like, share and subscribe. I will bring some more important technical topics in the next video. May Allah make our project successful. Amen. Wa akhiru dawana anil hamdulillahi rabbil alamin. Assalamu alaikum. Video Tips: • Show the equations by animating them (the compounds are mixing with water to form new compounds) • Use 3D models of C-S-H gel or simple graphics • The audience will like it more if you add a short talk with the engineer. If you want, ask them to simplify this script or add more detailed chemical equations. 2. Jabale Rahmat Tower (Land area 10 katha, B+G+11 floors, 4 units per floor, total 44 shares.
