Production Practice for Large Prestressed Fair-faced Concrete Wall Panel
This paper analyzes the quality defects and causes of fair-faced concrete,and performs system practice in three aspects,including control of raw materials,mold requirements and production technology,so as to realize the target of producing large prestressed fair-faced concrete wall panel by factory.In control of raw materials,it puts forward requirements for the workability of cement,admixture,aggregate,admixture and concrete;in terms of mold,it adopts old mold table combined with production technology,so as to realize excellent effect of fair-faced finish;in terms of production technology,starting from the actual circumstance of prestressed tensioned mold table of factory and management system,through strict control of the quality of raw materials,the formula of concrete,mold processing technology,component stacking protection and finish protection measures,it realizes the whole process of large prestressed fair-faced concrete wall panel from theoretical research to practical production,and it provides a new idea for mass production of fair-faced concrete component by assembled industry factory.
