总结它表明，在恒定的应力/强度比的持续负载下的标本有一个简单的蠕变和水泥浆在混凝土中的量之间的关系。水泥含量也影响蠕变速率，较稀混合料比富混合料更早达到其长期蠕变的给定比例。这种行为被证明是有关的增加率的强度ofsamples，而在负载下，并验证了普通和快速硬化波特兰水泥。从建立的关系预测蠕变进行了讨论。
Summary It is shown that for specimens subjected to a sustained load at a constant stress/strength ratio there is a simple relation between creep and the amount of cement paste in the concrete. The cement content affects also the rate of creep, leaner mixes achieving a given proportion of their long-term creep earlier than rich mixes. This behaviour is shown to be related to the rate of increase in strength ofthe specimen while under load, and is verified for ordinary and rapid-hardening Portland cements. The prediction of creep from the relations established is discussed.
