Slag, an industrial by-product, can partially substitute portland cement. High slag contents produce highly durable concretes and help reduce the CO2 emissions due to cement manufacture. Major problem of high slag content is often the high shrinkages resulting in the concrete. This project will systematically study all the factors affect the shrinkage behaviour in slag-blended cement concretes including the appropriateness of the standard shrinkage measurement method. The other aim is to develop a micro-mechanical model to understand the fundamental mechanism involved. This model will also lead to a better understanding of the mechanisms involved in shrinkage in all concretes.

矿渣是一种工业副产品，可以部分替代波特兰水泥。 高炉渣含量可生产高度耐用的混凝土，并有助于减少水泥生产过程中的二氧化碳排放。 高矿渣含量的主要问题往往是高收缩导致的混凝土。 本项目将系统地研究影响掺矿渣水泥混凝土收缩性能的所有因素，包括标准收缩测量方法的适当性。 另一个目的是开发一个微观力学模型，以了解所涉及的基本机制。 该模型也将导致更好地理解所有混凝土中的收缩机制。
