Composites Based on Alternative Raw Materials at High Temperature Conditions
(Budapest University of Technology and Economics, 2017-10-24)This paper presents newly developed polymer-cement composites. The primary binder (cement) was partially substituted by use of blast-furnace slag and high-temperature fly ash. A lightweight aggregate – agloporite (grain ... -
Alternative Evaluation of the grindability of Pozzolanic Materials for Cement Production
(IOP Publishing, 2017-10-25)All conventional methods for the evaluation of grindability require a specific grinding instrument. These grinding instruments do not have any other practical use and thus are not very common. This paper focuses on the ... -
Variability in cement properties - influence on bleeding of cement paste
(IOP Publishing, 2018-06-15)The aim of this study is to find relation between cement properties and tendency of cement paste (concrete) to bleeding. We tested 19 cement samples collected from different batches. -
