全文共分为四个部分:
第一部分为绪论。主要介绍了本研究的背景和意义,概述了本领域内的现状。
第二部分详细的介绍了本研究采用的材料和实验仪器,还介绍了实验方法和实验内容。
第三部分为实验结果和分析。首先,通过外加剂对水泥砂浆性能的试验,总结了其影响规律。然后在外加剂作用机理的指导下对实验数据进行收集整理,通过图表分析,得出了外加剂的最佳掺量。
第四部分为结论与展望。首先总结了早强剂的掺量与水泥早强关系的规律;然后结合早强剂的前景和发展方向,指出了当前我国外加剂生产方面存在的一些误区,并且提出了自己的一些解决方案。
Early strength concrete admixture of development is the first in the history of the use of one of the species, early strength of concrete means to accelerate the development of the early strength of concrete admixtures. Its main role is to accelerate the pace of cement hydration, and promote the development of early strength concrete. At present, China's early strength is more commonly used for main chloride, sulphate, carbonate and the composite of early strength. A calcium as a strong organic compounds as early as agent, widely used in dry powder in mortar, a cement hydration accelerate and improve the performance of mortar early strength, and may play a role by water. This paper will be a calcium and other salts such as sodium nitrite, potassium dichromate, aluminum sulfate potassium, sodium, and other composites, through the use of the complex mix of different experiments to study its early strength of cement mortar effect.
