The concrete industry is under increasing pressure to reduce greenhouse gas emissions. An immediate solution minimize the amount of Portland cement used by partially substituting other supplementary cementitious materials. This article presents results an experimental campaign on influence replacing with both calcined and uncalcined diatomites from filtration beer wine in production elements ma...

In order to reduce the carbon emission of planting concrete in process preparation, and realize application large amounts red mud geopolymer, this study, high silicon source materials blast furnace slag are added a content base geopolymer concrete, which can remove dependence on ordinary Portland cement provide new direction for comprehensive utilization mud. paper, effects different A (Alkali ...
This study has developed novel fully bio-based resorcinol epoxy resin–diatomite composites by a green two-stage process based on the living character of cationic polymerization. comprises photoinitiation and subsequently thermal dark curing, enabling obtaining thick non-transparent epoxy-diatomite without any solvent amine-based hardeners. The effects diatomite content compacting pressure micro...
Introduction: One of the factors that affects the rate of adsorption and removal of pollutants is the level of bed surface. Today, the use of active carbon substrates, synthetic zeolite such as Y and ZSM-5, are of great efficiency due to their high surface. In this research, diatomite modification was carried out using chemical and thermal processes to increase the bed surface and also the amou...
