    In general, a hose with an inside diameter of 20 mm can be used for pumping grout up to 30 m height. Hose connectors should not reduce the inside clear diameter available in the hose. A hose with a smaller inside diameter creates more friction and, as a result, a higher pumping pressure is required.

  • How to Design of Concrete Structures for Durability?

    Adequate concrete durability can be obtained in the design phase when a structure is conceived, and structural calculations are made, details are designed, materials and their proportions, as well as possible additional preventative measures, are selected. Prevention is further materialized as the concrete is prepared, placed, compacted, and cured. It would continue throughout the entire […]
