Combining light transmitting concrete with precise concrete casting technology, the Heng electronic weighing scales meets the majority of common uses. It mixes ultra-high-performance concrete (UHPC) and recycled demolition leftover concrete as materials, providing impressive compression intensity while recycling waste. Light transmitting concrete, an emerging technology that has not yet truly entered daily life, gives a new digital display experience, and an interesting juxtaposition of the light (electronics) and the solid (concrete). The acrylic fiber is cast in concrete of 10mm and more than 160 LED light dots form a one-to-one matrix on a circuit board under the fiber, which ensures clear display.
