Abstract
Delayed-release or controlled-release chemical additives are being studied by scientists as a potential solution to effectively and rationally use additive components in the production of cement mortar mixes, ready-mixed concrete. This paper synthesizes delayed-release additive by high-speed cutting-mixing method from two main components, fly ash and SNF additive powder. Releasing SNF from the pellets was described, clarified, and partially quantified through UV-vis spectral analysis, FTIR, OM, and SEM analysis. In addition, the effects on the workability of the mortar were also carried out. The results show that the pelletizing efficiency of the super-speed mixing technique and the positive effects on the mortar properties such as workability and compressive strength.
