Impact of Setting Retarder Incorporation on Foam Concrete Properties
Original language description
This study deals with the low stability of the pre-made foam used for foam concrete manufacturing. Previously, it was observed that foam mixed with fresh concrete quickly deteriorates. Such a process in general results in insufficient foam concrete porosity. Based on a US patent, the following solution has been suggested: adding setting retarder into the concrete composition. Four sets of samples were manufactured – a reference sample and three samples containing 0.1, 0.3, and 0.4 wt. % of setting retarder. For those samples, bulk density, strength, and sound absorption were measured. Based on the obtained results, it was decided that setting retarder addition results in better foam stability and therefore in higher total porosity. The best results were provided by the sample containing 0.3 wt. % of retarder.
