This paper presents experimental investigations on the early-age behavior of zero-slump concrete. In this context, compaction behavior and green-strength are used to characterize the early-age behavior of zero-slump concrete. First, the influence of the granulometric properties of the fines is discussed in detail. For this purpose, the early-age behavior of two different fines (quartz flour and fly ash) is investigated by means of the intensive compaction test (IC-test). The tests on the influence of the fines focus on effects caused by differences in the particle shape and the use of a plasticizing admixture. The conducted tests on the compaction behavior of the fines and their corresponding green-strength are extended to continuously graded granular mixes. Here, the influence of optimized particle packing on the early-age behavior is presented and a comparison based on the aforementioned quartz flour and fly ash is made. |
