Preparation and Study of Resin Translucent Concrete Products

Abstract

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.

Mechanical Analysis of Fly Ash-Based Light Transmitting Concrete by using Optical Fiber

“…It can be analyzed from Figure 9 that the LT Ratio increased with the increase in the percentage of POF. Previous research also shows the same trend for this test [13,14,15]. Figure 5 gives the details of the light passing through POF, and Table 6 describes the values obtained from the instrument.…”

Illumination of Interior Spaces through Structures Made of Unified Slabs of High-Performance Light-Transmitting Concrete with Embedded Optical Fibers

“…It was built by the Italcementi Group using a material created known as i.light [25]. I.light is a special concrete mixture to which a plastic matrix has been added, enabling the transmission of light from the exterior to the interior [26,27].…”

Light Transmitting Concrete: A Review

“…Concrete's quality and durability depend on the LTC's physical characteristics. Even though, the concerning literature is inadequate on the physical properties of LTC as accounted by [2,35,37,60], which normally included criteria to recognize the physical properties of concrete such as fresh concrete workability, ultrasonic pulse velocity (UPV), pore ratio and concrete density.…”

“…This reduction was found in the range of 6% to 20%. Furthermore, Juan and Zhi [2] have studied experimentally and numerically the properties of light-transmittance and mechanical, as well as the thermal performance of a novel kind of resin translucent mortar-based concrete [42]. The research pointed out that LTC has 0.38 W/(mk) thermal conductivity, which is 60% lower than the standard concrete of 0.89 W/(mk).…”

“…As a result, it is the most used human-made material globally. Numerous varieties of concrete exist [1][2][3][4][5][6][7][8][9][10], of which, light-transmitting concrete (LTC), or translucent or transparent concrete (TC), has drawn significant attention of concrete technologists and global researchers due to its significance, usefulness, and unique properties. Its ability to transmit light not only results in an improvement concerning visibility, but also reduces the light energy demand of buildings [1].…”
