一般水泥硬化28天后强度仍继續增长,如能很快了解水泥后期强度增长情况,并在混凝土結构設計中充分利用水泥石的后期强度,則可在保証工程质量的前提下,減少混凝土中水泥用量,从而节約大量水泥。本文就水泥后期强度增长的机理及其快速試驗法加以探討。一、水泥后期強度增长的机理根据近代对水泥水化产物及其結构組成的研究,可以将硬化后的水泥石分成三个基本組成部分:
Generally, the strength of cement continues to increase after 28 days. If you can quickly understand the late growth of cement, and make full use of the later strength of cement stone in the concrete structure design, you can reduce the cement content in the concrete under the premise of ensuring the quality of the project. The amount to save a lot of cement. In this paper, the mechanism of the late strength growth of cement and its rapid test method are discussed. First, the mechanism of late cement strength growth According to the modern study of cement hydration products and their structural composition, the hardened cement stone can be divided into three basic components:
