“…Although researches on the transparent concrete have obtained some achievements over the past decades, transparent concrete cannot be regarded as a mature building material. e method mentioned above can achieve the production of transparent resin concrete [11][12][13]. However, the primary focus of the transparent concrete technology previously has been on its aesthetic appeal and its application in artistic design [14][15][16].…”

The development of new building materials is a crucial engine for promoting the development of green energy efficient buildings. In this paper, based on the excellent properties of light guiding of resin materials, a new type of resin translucent mortar-based concrete (RTMC) was researched; meanwhile, transmittance properties, mechanical properties, and thermal performance were studied, respectively. The results showed that the resin material possessed excellent light transmittance within the thickness of 100 mm, which can be as high as 93%. Moreover, when the area ratio was within 5%, the compressive strength of RTMC was close to that of plain concrete. Besides, RTMC had excellent thermal performance that the thermal conductivity of RTCM was 0.3815 w/(m·K), which was 60% lower than 0.89 w/(m·K) of plain concrete.

“…Materials that possess high translucency or higher light transmittance can be used for LTC production. The transmission of light by optical fibres is sufficiently bright and efficient that almost no light is lost by the fibres [15][16][17][18]. Thus, the invention of LTC is an excellent solution for transmitting light inside structures.…”

Recently, research attention has been drawn to the application of novel, unique, and innovative types of construction materials to fulfil diverse objectives associated with the ground-breaking concept of “Greener Architecture”, in order to improve the overall economic value and quality of construction. Among these revolutionary structural building materials is light-transmitting concrete, also referred to as translucent or transparent concrete. This material is based on the concept of nano-optics, which allows exterior light to transmit through internal spaces in which light elements, namely optical fibres, are incorporated during the material’s manufacture. The current review assesses earlier studies of translucent concrete, focusing on its applications, and the appropriate ratio and arrangement pattern of optical fibres. This study also investigated the light-transmitting, mechanical, thermal, and energy-saving properties of translucent concrete by analysing research conducted during the past decade. However, numerous material restrictions and research gaps were found in the earlier literature on this concrete. The principal restrictions relate to the material’s low material strength and the identification of the optimum ratio of fibres. The main gaps identified among the reviewed research investigations relate to tests aiming to identify the influence of dissimilar ratios of optical fibres on the material’s strength and energy-saving properties. In the current review, we also identify and recommend future areas of research, and provide suggestions to address the existing research gaps. Finally, we review the types of translucent materials, their properties, and their advantages and disadvantages, and provide illustrations and value-added applications. The aim is to promote translucent concrete as an attractive, promising, and innovative building material for the construction industry.

“…Hungarian architectÁron Losonczi introduced the first concept of light transmitting concrete in 2001, and the first prototype of the translucent concrete panel was successfully developed in 2003 [8]. TC is a new ecofriendly construction material, and there exist few previous experimental studies.…”

Energy conservation is an emerging global issue for sustainable infrastructure development. The building sector energy demand accounts for approximately 34% of the world’s energy demand, and artificial lighting consumes around 19% of the total delivered electricity globally. Developing a new kind of building material that can reduce the demand for artificial lighting energy is vital. This research attempts to address such issues through the development of translucent concrete façade using locally available materials that can be used as energy-saving building material. Bulk density, compressive strength, and flexural strength of translucent concrete containing 2%, 4%, and 6% volume ratios of plastic optical fibers (POF) were studied. Moreover, the flexural toughness of translucent concrete façade panels integrating 6% volume ratio of POF was also investigated. The experimental results showed that using up to 6% volume ratio of plastic optical fibers had no adverse effect on the bulk density of translucent concrete. Translucent concrete specimens exhibited relatively lower compressive and flexural strengths compared to the reference concrete. However, it was evidently observed that the compressive strength of translucent concrete increased with increasing the volume ratio of POF. The flexural strength of translucent concrete was observed to decline with increase in the volume ratio of POF. Results demonstrated that translucent concrete panels have better flexural toughness, ductility, and energy absorption capacity than the reference concrete panel. The energy-saving, environmental conservation, and aesthetic and structural performance improvements stemming from the application of translucent concrete façade panel as architectural wall would foster the development of green and resilient buildings as well as contribute to sustainable construction.
