Microstructural and Mechanical Properties of Alkali Activated Colombian Raw Materials
Microstructural and mechanical properties of alkali activated binders based on blends of Colombian granulated blast furnace slag (GBFS) and fly ash (FA) were investigated. The synthesis of alkali activated binders was conducted at 85 °C for 24 h with different slag/fly ash ratios (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100). Mineralogical and microstructural characterization was carried out b...
متن کاملAtrazine removal from water by polycation-clay composites: effect of dissolved organic matter and comparison to activated carbon.
Atrazine removal from water by two polycations pre-adsorbed on montmorillonite was studied. Batch experiments demonstrated that the most suitable composite poly (4-vinylpyridine-co-styrene)-montmorillonite (PVP-co-S90%-mont.) removed 90-99% of atrazine (0.5-28 ppm) within 20-40 min at 0.367% w/w. Calculations employing Langmuir's equation could simulate and predict the kinetics and final extent...
متن کاملconstruction wastes as raw materials for geopolymer binders
it has been shown that geopolymerization can transform a wide range of waste aluminosilicate materials into building materials with excellent chemical and physical properties such as fire and acid resistance. in this research work, geopolymerization of construction waste materials with different alkali-activators based on combinations of na2sio3 and naoh has been investigated. a number of syste...
متن کاملThe controllable construction and properties characterization of organic–inorganic hybrid materials based on benzoxazine-bridged polysilsesquioxanes
Using a hydrolysis condensation of triethoxysilane to prepare a synthetic benzoxazine-bridged bis(triethoxysilane) compound (BS), a series of benzoxazine-bridged polysilsesquioxanes precursors were prepared with different degrees of hydrolysis condensation. Ring-opening thermal homopolymerization of the benzoxazine rings in these precursors was employed to obtain several organic–inorganic hybri...
متن کاملAdhesives with Different Phs: Effect on the Mtbs of Chemically Activated and Light-activated Composites to Human Dentin
PURPOSE To evaluate the bond strength between human dentin and composites, using two light-activated single-bottle total-etch adhesive systems with different pHs combined with chemically activated and light-activated-composites. The tested hypothesis was that the dentin bond strength is not influenced by an adhesive system of low pH, combined with chemically activated or light-activated composi...
