Calcium aluminate cement-based blends for application to fill in bone defects
(2020-12-01)
Introduction: The need to treat bone defects is increasing dramatically as the population grows old. Calcium aluminate cement, CAC, has been applied to fill in bone defects. CAC has been used in orthopedics, as it can avoid ...

Possibilities of reusing sugar cane straw ash in the production of alternative binders
(2016-01-01)
Sugar cane production is increasing in Brazil due the demand in manufacturing sugar and alcohol. During production process, several wastes are generated, such as sugar cane straw. After a burning process of this waste ...
Portland blended cements: Demolition ceramic waste managementCementos Portland con adiciones: manejo de residuos cerámicos de demolición
(Instituto de Ciencias de la Construcción Eduardo Torroja, 2017-01)
Demolition ceramic wastes (DCWs) were investigated in order to determine their potential use as supplementary cementitious materials in Portland Blended Cements (PBCs). For this purpose, three ceramic wastes were investigated. ...
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 ...
Comparative analysis of performance of portland cement blended with nanosilica and silica fume
(Universidad Nacional de Colombia Sede Medellín, 2010)
In this paper some physical properties of Colombian Portland cement type III replaced with nanosilica in percentages of 1, 3, 5 and 10% were evaluated. Main determined properties were fluidity, normal consistency, setting ...
Use of high-resolution thermogravimetric analysis (HRTG) technique in spent FCC catalyst/Portland cement pastes
(Springer, 2015-06-01)
Thermogravimetric analysis is one of the most common instrumental techniques used for the characterization of pastes, mortars and concretes based on both calcium hydroxide and Portland cement. Important information about ...
Does the colour of the waste glass affect their efficiency as supplementary cementitious material?
(Taylor & Francis, 2020-11)
Glass from the solid urban waste is presented mainly in amber, green and transparent colour. Regarding their reactivity, several studies argue that there are differences among each colour when they are used as supplementary ...
