Influence of Ultrafine 2CaO·SiO2 Powder on Hydration Properties of Reactive Powder Concrete [PDF]
Materials, 2015 In this research, we assessed the influence of an ultrafine 2CaO·SiO2 powder on the hydration properties of a reactive powder concrete system. The ultrafine powder was manufactured through chemical combustion method. The morphology of ultrafine powder and the development of hydration products in the cement paste prepared with ultrafine powder were ...

Lightweight Reactive Powder Concrete Containing Expanded Perlite [PDF]
Materials, 2021 This paper presents the test results of the lightweight concrete properties obtained by adding expanded perlite (EP) to an RPC mix in quantities from 30% to 60% by volume of the concrete mix. It has been shown that in these cases it is possible to obtain concrete containing 30% by volume with density of approximately 1900 kg/m3 and the compressive ...
