碩士 === 淡江大學 === 建築學系碩士班 === 93 === The study main for concrete mixture proportioning, when to calculate after whole mixture proportioning, the concrete to appear not enough of the slump and work, so when construction often add water to use as convenient concrete to pour into The experiment with variables is “aggregate maximum size”, “slump”, “water to cement ratio” are to analyze every variable and real water to cement ratio, for concrete strength by effect degree, and to provide many variables synthetic contrast. Final to provide correlation a proposal and reference. Outline of each chapter: Chapter.1 Describing the motive, purpose, configuring flow and method of this research. Chapter.2 From the relevant document gathered, to distinguish three part of the “concrete strength influence factor”, “concrete mixture theory” and “concrete quality control” to inducing and organizing. Chapter.3 For experiment program, to address three experiment with variables supposition, experiment with the flow path, experiment with materials basic nature, experiment with method and facilities. Chapter.4 To use the experiment data, to make use of the software to put things in order, and further discussion relation of the variables data, of besides to put things in order and analyzes, this chapter still to establish linear model and analyzes to compare. Chapter.5 Conclusions and suggestions induced from this research: 1) The whole between a reality water content and original data are difference. 2) When water to cement ratio, aggregate maximum size more and more little, and slump more and more larger, the concrete strength can be more and more larger. 3) Concrete strength to produce some effect of the reality water to cement ratio, aggregate maximum size and slump, to use as reality water to cement ratio effect concrete strength the most apparent. 4.) If can to use the variables difference more to mince, can’t to know in some one group have a change trend, especially when relevance factor R2 value to be close to zero of the linear, can to go a step further discussion.
