ESE-162-L Box Apparatus

The L Box Apparatus is a specialized testing device designed to measure the flowability and stability of fresh concrete, particularly in self-compacting concrete (SCC) applications. This equipment is primarily used to assess the ease with which concrete flows through reinforcement in structures, an important factor for ensuring uniformity, durability, and ease of placement in complex formwork.

Consisting of a vertical and horizontal section that forms the shape of an “L”, the L Box measures the passing ability and filling ability of concrete. When the concrete is placed into the vertical section, the apparatus uses a free-fall method to allow the concrete to pass through the horizontal section, which is fitted with bars to simulate reinforcement. The time taken for the concrete to flow through and the resulting distance it travels are recorded, providing a valuable indication of the concrete’s viscosity and its ability to fill gaps around reinforcement without segregation.

Constructed from high-quality materials, the L Box Apparatus is built to withstand repeated use and offers precision in results. It complies with various international standards for concrete testing, making it a reliable tool for laboratories, construction sites, and research facilities.

Used predominantly in the design and testing of self-compacting concrete, the L Box Apparatus is essential for ensuring that concrete mixes will behave as intended during placement and curing. This testing device is an indispensable tool for civil engineers, contractors, and researchers involved in the development of high-performance, flowable concrete materials.
