混凝土由水泥、水和粗细骨料组成，影响其强度的因素主要有：水灰比、水泥标号、骨料的质量、养护龄期、后期护养和施工方法等。混凝土具有诸多优点，如较高的抗压强度和耐久性；就地取材成本低；混凝土拌合物的可塑性良好，可以塑造成任意的结构形式、尺寸；与钢筋具有相近的线膨胀系数，能与钢筋牢固地粘结成坚固、耐久、抗震且经济的钢筋混凝土结构等。本文主要针对混凝土的配合比例进行试验研究，得出了提高混凝土强度的合理配比工艺。

Concrete is made up of four basic materials, which are cement, water, sand and stone. The factors influencing the concrete strength are water-cement ratio, cement mark, the quality of aggregate, curing period, the late maintenance and construction method, etc. Concrete has many advantages, such as strong strength and durability, low cost of local materials, fine plasticity of concrete mixture, and it can be modeled into any structure and size. Because of the similar expansion coefficient of concrete to rebar, its combination with rebar composes reinforced concrete structure, which is strong, durable, antiseismic and economical. In this article, the experiment about mixing proportion of concrete is carried out, and the reasonable ratio and technologies are obtained for improving the concrete strength.
