A Study on the Characteristics of Palm-Based Polyurethane as a Lightweight Aggregate In Concrete Mix

Abstract

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

Study of the Characteristics of Polyurethane as a Sustainable Material used for Buildings, Polymer Composite, Biomedical, and Electronics Application

“…These foams are made up mostly of non-linear materials, and their characteristics are decided by thickness, internal air cavities, and the kind of crosslinking present in the structure of their molecules. Polyurethane foams are often classified as flexible, partially flexible/partially rigid or rigid concerning the chemical system, the stubbornness of the resin employed as a matrix, the mechanical responsiveness of the foams, and their cross-link identities [38].…”

Development and Characterization of a Sustainable Bio-Polymer Concrete with a Low Carbon Footprint

“…Recently, studies were directed toward investigating the potential of using bio-based polyurethane aggregate in concrete. Sari et al [ 30 ] studied the performance of using palm oil-based PU to partially replace aggregates from 0% to 3% to produce lightweight concrete. It was reported that as the aggregate replacement with palm-based PU increases, the compressive strength decreases and the thermal conductivity of concrete increases.…”

Influence of wood flour on the mechanical properties of birch flour reinforced thermoplastic polyurethane composite

“…Several research works have been carried out to identify the parameters that govern the mechanical behavior of particulate composites. Generally, it has been found that the reinforcement effect increases with decreasing particle size and with the increasing of adhesion to the matrix [19]. Additionally, one observes a reduction in composite strength with increasing filler amount due to poor adhesion between the hydrophilic wood and the hydrophobic polymer [27].…”
