The following are the process of manufacturing good concrete. They are Batching Mixing Transporting Placing Compacting Curing Finishing Batching Batching involves volume batching in terms 35 litres and weight batching in terms of 50 kg. Automatic batching plants - suitable for ready mix plants. Mixing Mixing involves both hand mixing and machine mixing. Mixers involved are tilting, non tilting and reversing. Transporting concrete Mortar plan Wheel barrow, hand cart Crane, bucket and rope way Truck mixer and dumpers Belt conveyors Chute Skip and hoist Pump and pipe line Helicopter Concrete production is the process of mixing together the various ingredients water, aggregate, cement and additives to produce concrete. Nowadays concrete production takes place in a large type of industrial facility called concrete plant. In US 70% of the concrete is produced in concrete plants where as in India only 25% is produced in concrete plants. Conc
Shotcrete Shotcrete is mortar or concrete conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique. Shotcrete undergoes placement and compaction at the same time due to the force with which it is projected from the nozzle. It can be impacted onto any type or shape of surface, including vertical or overhead areas with or without reinforcement. Shotcrete is usually an all inclusive term that can be used for both wet mix and dry mix versions. In the pool construction trade however, the term shotcrete refers to wet mix and 'gunite' refers to dry mix, these two terms are not interchangeable. Types of shotcrete Fibre reinforced shotcrete Unreinforced shotcrete is a brittle material that cracks and displaces when subjected to tensile stresses and strains. Addition of fibres to the shotcrete mixture adds ductility to the material, energy absorption capacity and impact resistance. Composite material is capable of sustainin
