“…In this code, a lightweight concrete without natural sand is termed "all-lightweight concrete," and lightweight concrete in which all of the fine aggregate consists of normal weight sand is termed "sand-lightweight concrete." e density of lightweight concrete used in the model is 1800 kg/m 3 , and the density of normal weight concrete is 2500 kg/m 3 . Modulus of elasticity of each model is calculated according to ACI 213 [8].…”

“…Ramazan Demirboga and Rustem Gul in 2002 [3] had reported that thermal conductivity of concrete made up of expanded perlite and pumice aggregates with replacement of cement with fly ash and silica fumes with 10%, 20%, and 30% by weight gives good results for thermal conductivity of concrete. ermal conductivity of concrete is decreased by 43.5% in expanded perlite aggregates.…”

Concrete structures are prone to earthquake due to mass of the structures. e primary use of structural lightweight concrete (SLWC) is to reduce the dead load of a concrete structure, which allows the structural designer to reduce the size of the structural members like beam, column, and footings which results in reduction of earthquake forces on the structure. is paper attempts to predict the seismic response of a six-storied reinforced concrete frame with the use of lightweight concrete. A well-designed sixstorey example is taken for study. e structure is modelled with standard software, and analysis is carried out with normal weight and lightweight concrete. Bending moments and shear forces are considered for both NWC and LWC, and it is observed that bending moments and shear forces are reduced to 15 and 20 percent, respectively, in LWC. e density difference observed was 28% lower when compared NWC to LWC. Assuming that the section and reinforcements are not revised due to use of LWC, one can expect large margin over and above MCE (maximum considered earthquake; IS 1893-2016), which is a desirable seismic resistance feature in important structures.

“…Commercial river sand with particle size of 5 mm following BS882: 1983 standard was used. The lightweight aggregate, LWA used was rigid polyurethane (PU) that has been ground and sieved to particle size of 5 mm (Kan & Demirboga 2009;Mounanga et al 2008).…”

Research on the development of lightweight concrete (LWC) utilizing wastes and natural resources as lightweight aggregates (LWA) is increasingly gaining attention worldwide due to sustainable and environmental concerns. A new alternative is using palm kernel oil polyol (PKO-p)-based polyurethane (PU) as filler. Rigid PU is a block copolymer comprised of a monomeric . The property of PKO-p, PKO-p, Penyelidikan dalam membangunkan konkrit ringan (LWC) menggunakan bahan buangan dan sumber semula jadi sebagai agregat ringan (LWA) semakin mendapat perhatian dunia disebabkan oleh faktor kelestarian bahan dan kebimbangan terhadap alam sekitar. Satu alternatif baru dalam menghasilkan poliuretana (PU) sebagai pengisi adalah dengan menggunakan bahan berasaskan minyak isirung sawit (PKO). Poliuretana tegar adalah blok kopolimer yang mengandungi poliol PKO (PKO-p) dan 2,4-difenilmetana diisosianat (MDI mentah). Sifat
