![]() It can be used in aircrafts or in buildings for showing the path to emergency exits.It can be used to illuminate speed breakers on highways at night.It can be used in furniture either for decorative purposes or can be used in handles.įig 5: Bar unit made of translucent concrete.It can be used as partition walls between dining room and hall.Also, it gives a shiny appearance during sunset and during daytime it perfectly seems as a concrete block. The rays of sun on falling on such concrete hits at a lower angle resulting in bigger intensity of light.įig 4: Wall made from translucent concrete It can act as a building material for interior and exterior walls.Some of the applications of translucent concrete are. Also, holes are driven on steel or wooden plate to let those fibres pass through.Ĥ) The concrete mixture is then poured slowly with caution so that no disturbance is created to the optical fibres beneath.ĥ) Accumulation of void is prevented with the help of vibrating tables.Ħ) After 24 hours, the mould is removed and the mud is pulled off.ħ) Then the extra-long fibres are cut to the same size as thickness of panel.Ĩ) The surface is then polished with the help of sand paper or polishing paper resulting in finishes ranging from semi-gloss to high gloss. Clay or mud are placed on the sides for easy demoulding as optical fibres are exposed to the mould.ĬOURTESY: SSRG INTERNATIONAL JOURNAL OF CIVIL ENGINEERING (SSRG-IJCE)Ģ) The optical fibres are cut in such a way that it can be placed perfectly inside the mould.ģ) The optical fibres are placed in layer wise. Buffer coating- It is a plastic coating which protects the fibre from any kind of damage.Īlso, other types such as Multimode Fibre, Single-mode Fibre, Multimode Step-Index Fibre, Multimode Graded-Index Fibres are used.Ħ) Waste Glass- These are collected from industrial wastes and are hammered, crushed into smaller pieces.ħ) Superplasticizers- Examples are Neoplast, Glenium, Polyplast SP HPC.ġ) Mould of steel or wood is prepared of rectangular size.To keep the reflection in the core the refractive index of the core must be greater than that of cladding.Cladding – It is the outer optical material which surrounds the core and it reflects light back to the core.Core – It is a thin glass center of the fibre through which light emits.Sand is mostly used for this.ģ) Coarse aggregate- This includes crushed granite, crushed hard basalt chips, etc.Ĥ) Water- It should be free from all kinds of acids, alkalies, oils or other organic impurities.ĥ) Optical Fibres- An optical fibre consists of three kinds of elements: Hence it increases the strength and reduces porosity. Portland cement is the most common type used in constructions.Ģ) Fine aggregates- It is a chemically inactive material which serves the purpose of filling the voids in coarser particles. Some of the materials used in production of Translucent concrete are-ġ) Cement– It is a binder material that sets and hardens after a definite period of time depending upon its type. As polymer based optical fibres and optical glass fibres were developed, it led to the increased rate of invention in this field.įig 1: Translucent Concrete building known as Lucem GmbH It was first mentioned in a Canadian Patent in the year 1935. Its light transmitting is mainly due to uniform distribution of high numerical aperture Plastic Optic Fibres (POF) and hence it is also known as LiTraCon.It is produced by adding about 4% to 5% of optical fibres by volume in concrete mix. RTCM could effectively improve the indoor daylight condition and visual comfort.Translucent concrete is a light transmitting concrete based building material. The results revealed that RTCM had excellent light transmittance and thermal conductivity. In addition, the cooling/heating load in the present test conditions could be reduced by nearly 20%. The operating time of the artificial lighting device was shortened from 72% to 41%. The natural lighting coefficient increased by nearly 100%, and the lighting uniformity improved by nearly 50%. ![]() The building energy consumption and daylight level were evaluated through energy and daylighting simulation with the help of Autodesk Ecotect Analysis 2011 software. The light transmission and thermal conductivity of resin translucent cement-based material (RTCM) were measured by the optical power method and flat plate method, respectively. As a consequence, this study offered an investigation on a novel building envelope material by means of the polymethyl methacrylate resin embedded into concrete, which can provide excellent illumination from natural light and an excellent combination of shielding performance and clarity. It is of significance to dwell on creative technology that takes advantage of solar energy for light and heat supply. Buildings consume large amounts of energy, and lighting and maintaining a comfortable temperature consume a substantial amount of this energy.
