Strength-porosity relationships in lime-pozzolan mortars.
November 1, 2006... Abstract Lime-pozzolan mortars are the hydraulic mortars widely used in the past for the construction of monumental structures and nowadays for their repair. These mortars are of higher porosity and lower strength in comparison with...

Influence of soaking and polymerization conditions on the properties of polymer concrete.
November 1, 2006... Abstract An experimental investigation was conducted to study the effect of soaking time and polymerization temperature on the mechanical and physical properties of polymer-impregnated concrete. Soaking time was controlled in 4, 8, 12, 16,...

Structural behaviour of eccentrically loaded precast sandwich panels.
November 1, 2006... Abstract Results of an experimental investigation to study the ultimate strength behaviour of precast concrete sandwich panels (PCSP) with steel truss shear connectors are reported. Six full-scale sandwich panels with variable slenderness...

Relationship between average pore diameter and chloride diffusivity in various concretes.
November 1, 2006... Abstract Since concrete is a heterogeneous composite material which is composed of cement, aggregate, mineral admixture, and so on, the microstructure of concrete is very important to predict transport property associated with the...

Development and structural testing of a composite-reinforced timber highway guardrail.
November 1, 2006... Abstract Various government agencies install timber guardrails on scenic highways and roads in lieu of conventional steel guardrails for aesthetic reasons. Most acceptable timber guardrails rely on a continuous steel backing member to...

A study on carbonation depth prediction for fly ash concrete.
November 1, 2006... Abstract Carbonation of fly ash concrete is studied by using two types of fly ash with different CaO contents. It is observed that under natural exposure environments, the carbonation rate is the highest when specimens are exposed in the...
