Alkali-Activated Hybrid Cement from Mineral Wool Fiber Waste and OPC
(MDPICentro de Investigación Innovación y Desarrollo de Materiales (CIDEMAT)Grupo de Investigación en Infraestructura (GII)Basilea, Suiza, 2023)
Análise do cimento álcali ativado quando sujeito à reação álcali-agregado
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2016-11-22)
The growing environmental concern has stimulated studies for the development of alternative cements, with reduced greenhouse gas emissions in its manufacture. One of these is the alkali activated cement (CAT), which in ...
Biomass ashes to produce an alternative alkaline activator for alkali-activated cements
(2022-02-01)
In the last decade, herbaceous and agricultural biomass have been used as an alternative energy source. As consequence, large amounts of residual ashes containing potassium (potassium-rich ashes) have been generated. Olive ...
Influence of calcium additions on the compressive strength and microstructure of alkali-activated ceramic sanitary-ware
(2018-07-01)
The ceramic sanitary-ware market generates large amounts of waste, both during the production process and due to construction and demolition practices. In this paper, the effect of different amounts and calcium sources ...
New use of sugar cane straw ash in alkali-activated materials: A silica source for the preparation of the alkaline activator
(2018-05-20)
Alkali silicates, expensive and highly pollutant chemical reagents, are required to produce the alkaline activator for high-performance alkali-activated materials. This study presents a new silica source for producing the ...
Mechanical refining combined with chemical treatment for the processing of Bamboo fibres to produce efficient cement composites
(Construction and Building Materials, 2021)
Alkali activated materials based on fluid catalytic cracking catalyst residue (FCC): Influence of SiO2/Na2O and H 2O/FCC ratio on mechanical strength and microstructure
(2013-03-29)
Reuse of industrial and agricultural wastes as supplementary cementitious materials (SCMs) in concrete and mortar productions contribute to sustainable development. In this context, fluid catalytic cracking catalyst residue ...

Mechanical and durability properties of alkali-activated mortar based on sugarcane bagasse ash and blast furnace slag
(2015-02-24)
Sugarcane bagasse is an agricultural waste which can be transformed, for cementing purposes, into an interesting material by combustion. Specifically, the ash (SBA) obtained by auto-combustion was used for preparing ...
Compressive Strength and Microstructure of Alkali-Activated Blast Furnace Slag/Sewage Sludge Ash (GGBS/SSA) Blends Cured at Room Temperature
(2017-07-01)
In the present work, ground granulated blast furnace slag (GGBS) and sewage sludge ash (SSA) blends were assessed for the production of alkali-activated pastes and mortars. Percentages of SSA to substitute GGBS ranged from ...
