Improving the quality of autoclaved aerated concrete panel based on QFD and DOE theory
Since the invention of autoclaved aerated concrete(AAC)used for blocks in Sweden in the 1920s,its applications have been expanded to many other areas,including wall panels,floor and roof panels,cladding panels and lintels.AAC production in Europe has slowed down considerably,while the industry is growing rapidly in Asia due to the strong demand in housing and commercial space.China is one of the largest markets in AAC manufacturing and consumption.However,the quality of AAC is unstable and most AAC producers have a low yield procedure in China.In this paper,an integrated methodology combining Quality Function Deployment(QFD)and Design of Experiment(DoE)was proposed to improve the quality of AAC panels.QFD is a useful tool for managing cross-functional design teams and exploring the customer needs.It achieves the maximum custom satisfaction by translating customer requirements to the engineering world.DoE was widely used for the design of multi-factor experiments.It provides adequate information based on limited time and cost.Customer requirements were collected through interviews and grouped by Affinity Diagram.Through construction of the 1st phase and the 2nd phase of QFD matrices,customer requirements were transferred to technical attributes and process procedures.Raw material composition,steam curing method and appropriate arrangement of reinforced steels were identified as the critical processes which affect the quality of AAC panel the most.Design of Experiment(DoE)was adopted to perform a series of experiments to obtain the best combination of raw material and steam curing method.Through application of the proposed methodology to AAC panel manufacturing,the product qualification ratio of AAC panel increased from 50%to 92.8%,higher than the expected 85%.
