AAC block is made of Portland cement, fine aggregates (fly ash or sand), water and an expansion agent. The autoclaving process results in the production of air voids in the material, making it less dense, easy to cut/ mould and better insulating.

What is the Post Tension Slab - Civil Snapshot

The slab which is tensioned after constructing slab is called Post tension slab. Reinforcement is provided to resist the compression. In Post tension slab the reinforcement is replaced with cables/ steel tendons. Post-tensioning provides a means to overcome the natural weakness of concrete in tension and to make better use of its strength in compression. …

Importance of Reinforcements in Masonry Building - Civil Snapshot

The walls, if constructed with plain masonry would be in capable of resisting the magnitude of horizontal shear and bending forces imposed on them during earthquakes. For this reason, in the modern reinforced masonry systems, reinforcing steel is incorporated to resist the shear and tensile stresses, so developed.
