随着建筑工业和结构设计理论的发展,要求及时地评定和控制混凝土质量。因此研究早期推定混凝土强度的方法,以便判定混凝土强度质量就显得十分必要。这对合理利用水泥活性,保证工程质量都有重要意义,同时也是现代化施工实行全面质量管理不可缺少的环节。按混凝土成熟度理论来推断混凝土强度的发展趋势,可以改善混凝土的养护工艺。按三个参数的双曲线函数所表达的S-M曲线,运用计算理论和测温技术,对不同龄期的温度进行量测,并对测得的数据进行正确处理和推算,即可绘制稳定的S-M曲线,可在强度管理上实际应用。虽然在水泥浆水化初期的水化反应是有限的,但是如果能在早期赋予良好的结构形态,即可对后期水化过程和强度产生显著影响。所以根据成熟度理论,先经初期低温养护,即可赋予水泥浆以良好的结构形态,并取得较高的极限强度。应用混凝土成熟度理论检测方法进行混凝土生产和施工质量控制,可及时分析问题,调整养护温度,可以节约大量资金和能源,收到巨大的经济效益,并使我国的混凝土质量水平得到较大的提高。
With the development of the construction industry and structural design theory, it is required to timely assess and control the concrete quality. Therefore, it is necessary to study the method of early estimation of concrete strength in order to determine the strength and quality of concrete. This is of great significance to the rational use of cement activity and the quality of the project. It is also an indispensable part of the implementation of total quality management in modern construction. According to the concrete maturity theory to infer the development trend of concrete strength, it can improve the concrete curing process. According to the SM curve expressed by the hyperbolic function of three parameters, using the calculation theory and temperature measurement technology, the temperature of different ages is measured, and the measured data are processed and calculated in a correct manner, and a stable SM can be drawn. The curve can be applied practically in intensity management. Although the hydration reaction in the initial stage of hydration of the cement slurry is limited, if it can give a good structural form in the early stage, it can have a significant effect on the later hydration process and strength. Therefore, according to the maturity theory, the initial low-temperature curing can give the slurry a good structural shape and achieve a higher ultimate strength. The use of concrete maturity testing methods for concrete production and construction quality control can timely analyze problems and adjust curing temperature, which can save a lot of capital and energy, receive huge economic benefits, and greatly improve the quality of concrete in China. .
