DEAD LOADS FOR DEAD LOAD (DL1) REFERENCE LOAD: UNIT WEIGHT OF CONCRETE = 23.54 kN/m3 2.354 kN/m3 at 100mm SLAB THICKNESS *2.354 kN/m2 is calculated from 100mm slab thickness multiplied by the concrete density of 23.54 kN/m3. So, 23.54 x 0.1 = 2.354kN/m2. Sullano, Ray Blanche U.OCTOBER 22, 2019SOFTWARE …

Five batches of specimens, each with 0%, 10%, 20%, 30%, 40% PP replacement (by volume) were molded and cured for 28 days. The compressive strength and bulk density of the specimens from these batches were determined and compared. Results showed that, generally, compressive strength and bulk density decrease as percent replacement …

Advantages of hollow block: The hollow block will give a different look as it reduces the energy bill to create an environmentally friendly environment in the building. Solid hollow blocks require less maintenance and provide insulation from sound, heat, and fire-resistant. The joints in these blocks require less cement mortar, little or no ...
