A study of the effect of cracks on the resonant frequency and dynamic modulus of elasticity of insulating brick by the dynamic testing method
Vertical cracks normal to the major axis of a standard fire brick will cause a lowering of the dynamic modulus of elasticity calculated.

Dynamic Analysis for Characterization of Novel Biomass Based Composities
… from forests constitute a significant asset of Mississippi State. Forests cover around 19.7 million acres (65%) of the total land area of Mississippi. Total annual economic impact of Mississippi’s forest products is about $17 billion. Creation of high-value products will lead to a number of …

Characterizations of concretes with alkali-activated binder and correlating their properties from micro- to specimen level
The manufacturing of portland cement (PC), the main binder of concrete, generates large amount of CO2 (a greenhouse gas), cement kiln dust (solid waste), and consumes significant amount of heat energy. Alkali-activated binder (AAB) is increasingly being considered as an environmentally friendly or …

Flexural behavior of a glass fiber reinforced wood fiber composite
The static and dynamic flexural properties of a wood fiber matrix internally reinforced with continuous glass fibers were investigated. When modelled as a sandwich composite, the static flexural modulus of elasticity (MOE) of glass fiber reinforced hardboard could be successfully predicted from the …

Short & long term properties of self-consolidating concrete incorporating fly ash and local aggregate
… examine the mechanical and durability properties of SCC to gain insights for the design and implementation of SCC in structures. This thesis presents the mechanical and durability experiments used for characterization and acceptance of SCC. Because there are many normally vibrated concretes (NVC) …

Durable high early strength concrete
… report on infrastructure by the American Society of Civil Engineers, 13% of Kansas public roads are in poor condition. Furthermore, reconstruction of a two-lane concrete pavement costs between $0.8 and $1.15 million dollars per lane mile. High early strength Portland cement concrete pavement …

Deterioro del hormigón sometido a ensayos acelerados de hielo-deshielo en presencia de cloruros
… due to freeze-thaw cycles in the presence of de-icing salts is a frequent cause of problems in concrete bridges and other civil infrastructures in Europe. Concrete damage generated by freeze-thaw cycles can be internal, mainly by cracking and/or external, like scaling (wear surface by …

Characterisation and properties of alkali activated pozzolanic materials.
Many of the waste materials produced from modem heavy industries are pozzalans, which develop cementitious properties when finely divided in the presence of free lime. This property allows a potential industrial use for this waste as a cement replacement material in concrete. An example of such a …

EFFECTS OF DEICING SALTS ON THE DURABILITY OF CONCRETE INCORPORATING SUPPLEMENTARY CEMENTITIOUS MATERIALS
The durability of concrete mixtures incorporating one of two supplementary cementitious materials (SCMs), slag cement or Class C fly ash, exposed to sodium chloride (NaCl), calcium chloride (CaCl2), or magnesium chloride (MgCl2) is evaluated based on damage due to wetting and drying and scaling, …

Determinación del módulo de deformación dinámico de un mortero de revestimiento a partir de muestras obtenidas en laboratorio e in situ
El módulo de deformación de morteros de revestimiento se considera una propiedad fundamental en la mayoría de los estándares y sin embargo es una de las menos determinadas en el laboratorio. Hay todavía pocos estudios sobre su evaluación a partir de muestras recogidas in situ y la mayor parte de …
