Abstract Concrete is widely used in the industry due to its effectiveness in terms of cost and strength. In this study, the introduction of bio-based aggregate as coarse aggregate in lightweight foam concrete will be investigated to find a better solution for fire incidents that are commonly happened. As such, lightweight foam concrete (LWFC) has been applied in many buildings especially in non-load bearing wall to enhance thermal conductivity, sound insulation and fire resistance. The aim of this research is to investigate the effect of incorporating bio-based aggregate namely oil palm shell (OPS) into lightweight form concrete in terms of strength properties and fire resistance. Three different concrete mix was designed containing different percentage of OPS aggregate replacement (0, 5, 10 and 15%). From the result, the compressive strength of the LWFC-CTR mixture had achieved the highest compressive strength at 28-day, which is recorded at 3.82 MPa. The fire resistance of LWFC-OPS 15% had showed a positive outcome with improvement by almost 23.5% compared to control mix at 15 minutes. Therefore, the major finding of this research is the incorporation of eco-friendly OPS aggregate has improved the fire resistance of lightweight foam concrete, which can be used as an alternative solution for non-load bearing walls.

Because of the high-rise of apartment houses, diversity of planar forms, and need for environmental improvement, the development of eco-friendly dry materials becomes necessary. Dry wall panels should be easy enough to use that they can be installed and dismantled, and have fundamental performance items for dry wall (sound insulation, fire resistance, strength, specific gravity etc.). In this study, we intend to develop dry wall panels using eco-friendly and recyclable byproducts of a thermal power plant such as fly ash and bottom ash. With the performance items and level set to develop dry wall, we developed dry wall panels by adjusting mixing ratio.

Functions of the wall and some of wall materials are introduced. Basalt filaments possess excellent properties with high strength, high temperature resistance, corrosion resistance, small hygroscopicity, small thermal conductivity and high sound absorption coefficient. High performance basalt fabrics can be gelatinized into compound cementitious materials with cement or gypsum. The performance of basalt compound boards mainly rely on the performance of basalt filaments. So basalt compound boards possess excellent characteristics with light-weight, high strength, fire prevention, sound insulation and heat preservation. It is green initiative and easy construction as new wall materials. Basalt compound cementitious materials possess good application prospect in the wall materials along with the development of production technology.

This study presents the results of a detailed acoustic investigation, systematized and with adequate equipment to the current regulations, carried out in an avenue of intense vehicular traffic located in front of a recently built architectural complex, based on concrete, aluminum, glass, and other materials, called the Postgraduate Unit, belonging to the National Autonomous University of Mexico. These measurements show that, in the initial design of the buildings, the most current knowledge about exterior-interior sound insulation through their facades was not considered. The data collected and the interviews conducted reveal that the Sound Pressure Levels rise, altering the Interior Acoustic Comfort, necessary for the performance of daily academic, administrative and research activities, resulting in permanent inconveniences for users, in addition to the saturation of areas, lack of adequate spaces and excessive unscheduled expenses. Paradoxically, empty spaces are observed in areas with high Sound Pressure Levels, which means that there is a certain level of architectural failure.

Two Samples

Lightweight steel concrete structures (LSCS) - an innovative energy-efficient building structure type that can be used both as load-bearing and as enclosing one. They consist of profiled steel - usually galvanized and cold-bent - filled with a monolithic foam concrete with a 400kg/m3 density and with fiber cement sheets sheathing. These structures can be used in industrial and civil buildings as internal and external bearing and enclosing wall structures and as slabs, energy-efficient roof covering. According to the LSCS production method, prefabricated panels (walls and slabs) and building site performed constructions are distinguished. The paper presents the testing results with the aim to determine the fire resistance limit of a slab panel fragment by bearing capacity (R), loss of integrity (E), loss of heat insulating capability (I) and fire hazard class. Two samples of a slab panel fragment were selected for the fire resistance high-temperature tests. The actual fire resistance limit of samples of the slab panel fragment is at least REI 60 with a uniformly distributed load 4 kN/m2.
