砂率、用水量和坍落度对道路混凝土强度的影响毕设论文.doc

毕业论文砂率、用水量和坍落度对道路混凝土强度的影响 摘 要水泥混凝土路面具有耐久性好，耐高温性强等特点，近几年来它被广泛用于机场、厂矿等工业民用建筑。但随着汽车保有量逐年的大幅度提高，水泥混凝土路面在繁重的交通的运营状态下破坏极其严重。这样的问题近几年来明显地暴露出来，并产生很多经济损耗。如何提高水泥混凝土路面的强度已成为工程建设所关心的问题。在各国学者对各种因素影响路面水泥混凝土强度的研究基础上，本文着重讨论了砂率、用水量、坍落度这三个因素对路面水泥混凝土强度的影响规律，找出最佳强度下的砂率、用水量、坍落度。关键词：水泥混凝土路面，强度，砂率，用水量，坍落度AbstractCement concrete pavement has good durability and high temperature resistant, in recent years it has been widely used in airports, factories, and other industrials and civil buildings. But with the substantial increasing in car ownership from year after year, under the heavy traffic operating condition, cement concrete pavement damages extremely. Such a problem in recent years exposed, and generate a lot of economic loss. How to improve the strength of cement concrete pavement has become the concern of the project construction.On the basis of studies about a variety of influence factors of cement concrete pavement of scholars from various countries, this article focuses on the effect of the strength of pavement cement concrete on these three factors including sand ratio, water consumption and slump, then to find the optimal intensity of sand ratio, water, slump.Key words: Cement concrete pavement；Strength, sand ratio；Water consumption；Slump目 录 TOC \o 1-2 \h \z \u HYPERLINK \l _Toc326853342 摘 要..
