“…[3] Although it has consistently discovered a variety of parameters (including cementitious material composition, the fine/coarse aggregates ratio, and the impact of test ages) that affect compressive strength. [11] Compressive strength is observed to rise as fibre content increases up to 4%, then reduction at 6% fibre content for all diameters. However, the concrete's compressive strength reaches its peak after seven days at 4% fibre concentration because higher fibre contents weaken the bonds that hold the material together.…”

By 2050, it is predicted that the manufacturing of regular cement for institutional, commercial, and residential structures will spew around 3800 tonnes of carbon dioxide into the atmosphere and use 38% of the world's energy. It has become crucial to create a new class of construction materials that combine eco-friendly, energy-saving, and self-sensing capabilities. Translucent concrete, created through innovation in the material sciences and the fusing of fibre optics and concrete technologies, helps to create structures that are cosier, more artistic, safe, and energy-efficient. The creation of Smart Transparent Concrete, based on its exceptional transparent and smart sensing qualities, is discussed in light of "green" standards and safe evaluation for engineering constructions that have attracted global attention. Dealing with its application and the benefits it offers in the area of smart construction, discover that it can save lighting power consumption, utilise an optical fibre to detect structural stress, and use this concrete as an architectural feature for a pleasing aesthetic sight of the building. Fly ash is used in concrete to explore the partial additional of cement with fly ash. Translucent concrete blocks can be used in many ways and implemented into many be highly advantageous. Keywords: Translucent Concrete, Optical Fiber, Fly Ash, Compressive Strength, Light Transmission.

“…When the curing period for the 28 th day was over, samples were tested for light transmissibility before they were subjected to the compressive strength test. This study adopted the light transmissibility test performed in the study of Tahwia et al [34]. In this test, the illumination values in lux were recorded using a lux meter, as presented in Figure 6.…”

Living up to a culture of sustainability and efficiency, the Light Transmitting Concrete or Litracon came to its prominence recently. Aside from that, the increase in the production of cement for building structures to facilitate various social dynamics has contributed to the world’s exponentially increasing carbon emissions. Thereby, this study acts upon both phenomena by partially replacing the cement in the concrete mix for producing Litracon blocks using an agricultural waste material called Sugarcane Bagasse Ash or SCBA while aiming to improve their structural performance. The study used five (5) mix designs of 2.5%, 5%, 7.5%, and 10% replacements, and a controlled mix with no replacement. Three (3) cubic samples of 150 mm side dimension for each mix were subjected to the light transmissibility test before the compressive strength test. Results showed that the illumination values in lux of 103 to 120 were at par with the Philippine illumination guidelines for interior rooms, from 100 to 150. Moreover, the highest recorded compressive strength result with SCBA percentage replacement was the 5% design mix at 28.81 MPa, and the 2.5% design mix had the lowest recorded compressive strength of 23.51 MPa. The results further showed that even with no significant relationship between the percentage replacements and compressive strength values from the two-tailed T-test, no significant difference between such strength values was found using the One-way ANOVA test. Thus, this supports the claim that SCBA can partially replace the cement used for the concrete mix of Litracon blocks.

“…It has been demonstrated that concrete mixtures can increase light transmittance to 21.4% with a volume ratio of 4% POF and 3 mm POF diameter. Good mechanical properties such as compressive strength are minimally affected [69].…”

Light-transmitting concrete as a building material already exists in many forms, but its light properties and the possibilities of using it to improve the lighting of interior spaces have not been investigated in detail yet. This paper focuses on the illumination of interior spaces using constructions made of light-transmitting concrete, which will allow light to pass between individual spaces. The experimental measurements carried out are divided into two typical situations using reduced room models. The first part of the paper focuses on the illumination of the room through the penetration of daylight through the ceiling made of light-transmitting concrete. The second part of the paper investigates the transmission of artificial light from one room to another through a non-load-bearing dividing structure composed of unified slabs of light-transmitting concrete. For the experiments, several models and samples were created for comparison. The first step of the experiment was to create slabs of light-transmitting concrete. While there are many options to produce such a slab, the best option is to use high-performance concrete with glass-fiber reinforcement, which improves the load transfer properties, and plastic optical fibers for light transmission. By adding optical fibers, we can achieve the transmission of light between any two spaces. For both of the experiments, we used reduced-scale models of rooms. Slabs with dimensions of 250 × 250 × 20 mm and 250 × 250 × 30 mm were used in three versions: concrete slabs with optical fibers, concrete slabs with air holes and solid slabs. The experiment measured and compared the level of illumination at several points in the model as it passed through each of the three different slabs. Based on the results of these experiments, it was concluded that the interior level of illumination of any space can be improved by using light-transmitting concrete, especially those without access to natural light. The experiment also assessed the strength properties of the slabs in relation to their intended use and compares them with the properties of stone slabs used as cladding.
