The powder tank adopts efficient dust collectors, fog spraying and other methods to greatly reduce the pollution of the dust to the environment. Besides, the discharge equipment and the exhaust system of the pneumatic system all adopt noise reduction devices to effectively reduce noise pollution. Concrete Plant Specifications
The construction of prefabricated concrete structures involves many different types of precast concrete (PC) components. Improper arrangements of the transportation, storage, and hoisting of the PC components could lead to unnecessary relocation of PC components, causing a delay in construction progress. To address this problem, this paper presented a dynamic optimization method for PC ...

Transportation and Installation Precast Concrete Transportation and Installation. Transportation is an integral part of any project involving precast concrete products. The advantage of manufacturing structural elements off-site can soon become a disadvantage if the transport and logistics are not managed correctly.
Routine police checks of cargo secured on trucks frequently raise the issue of whether such cargo has been secured and fastened properly in the case at hand. There is rather much room for interpretation with respect to concrete products and precast elements.
Transportation Issue: The construction site can be at a distant location from the Precast Concrete plant. In that case, the precast members must be carried to the site using trailers. In many cases, the reduced costs of Precast Concrete is compensated by the transportation cost.
