(57) A method and a technique for producing precast-cast-in-situ lightweight rigid building assembled from the modified hollow core slab and sandwiched hollow block wall segments. Three methods are presenting for incorporating shear and flexural reinforcements as well as traditional prestressed reinforcements in the hollow core slab. The modified hollow core slab and the sand­wiched hollow block wall segments are assembled in-situ by post tension to produce two way slabs and two way walls. The upper concrete fiber as well as the cast in-situ...
