A source of sand is proposed as an educational tool to aid in the identification of silica mineralogies and textures susceptible to alkali-silica reaction. This particular silica sand originates in the southern portion of the state of Veracruz, Mexico, and exhibits a wide variety of lithologies, A thin section produced from a cross-section through...

This work investigated the use of the <150 μm fraction of a calcined waste foundry sand (WFS) as filler in self-compacting mortars. WFS was calcined at 600–900 °C, referred to as calcined foundry sand (CFS). Self-compacting mortars were produced with cement replacement levels of 0–30 vol% with CFS and a limestone filler. WFS and CFS were characteri...

Este trabalho surgiu da necessidade de se otimizar composições de graute para utilização em obras de alvenaria estrutural de blocos de concreto. Como critério de dimensionamento, os grautes deveriam possuir uma resistência característica à compressão (fck) de 15 MPa, e, ao mesmo tempo, abatimento do tronco de cone de 20 ± 2 cm. Empregou-se uma meto...

The reliable estimation of the rate of chloride penetration in concrete is a major parameter in service life predictions. Electro-chemical test methods have the advantage of being fast while more long-term test methods can provide conditions that better approximate the in-service environment. This study investigates the performance of commonly used...
