| In construction, the growing dominance of concrete on the building cost and quality play a decisive role, but because of concrete quality problems caused by the construction of quality problems are not uncommon.6Sigma has been different applications in many industries as a quality improvement of today's more popular method. So this paper ,a concrete-POE is built on the basis of the DMAIC improvement model of 6Sigma Management and to improve the flow, and improvement of concrete compressive strength and control, to improve the concrete quality, corporate image and reduce the cost of construction is of great practical significance.This paper focuses on the application and research situation home and abroad and it has a detailed analysis on some related management theories in 6Sigma.the concrete-POE model is used to improve the compressive strength of concrete and control in the process X Construction Co.Ltd of Anhui Province Ministry of Y projects . In the implementation of the project preparation phase analysis of the present concrete situation, to collect the relevant strength data, and intensity data from the controlled process performance both state and analyze the current status of de facto control of concrete.In the optimization stage, mainly the use of cause and effect diagram analysis of the factors influencing the strength and the application of MINITAB software, an important influence factors on the compressive strength of a full factorial analysis, analyze the influence of concrete compressive strength of the key factors to improve the program. Finally, control the results of the program and assesses financial benefit.From the analysis of its economic effects, the application of concrete-POE improvement model has brought obvious results. It also solves a series of problems like the instability of concrete compressive strength, high intensity value, not being up to the standard and so on. And it saves the project over one million cost during a whole cycle. This paper closely connects theories with practical applications, and it provides a set of applicable methods to better solve other problems met in the construction practice. |
