A Comparative Study of the Seismic Behaviour of G+20 Storey Symmetrical Buildings Constructed with Light Weight Concrete and Normal Weight Concrete

International Journal for Research in Applied Science and Engineering Technology, 2023
Abstract: Concrete with a density of less than 2000 kg/m^3 is considered lightweight concrete. Structural lightweight concrete (SLWC) is used to reduce the dead load of concrete structures. The purpose of this research is to examine and compare the results of SLWC made with scoria and normal weight concrete (NWC) and normal and light weight concrete ...

Prediction of Creep Concrete in Lightweight Concrete with Pumice as Coarse Aggregate

Rekayasa Sipil
Concrete creep is the additional strain that develops in concrete under constant stress over time. In this study, lightweight concrete is created by entirely replacing coarse aggregate with pumice to reduce the concrete's overall weight.
