Guest editorial.
November 1, 2005... The use of concrete in Ireland can be traced back to the middle of the 19th century, in the foundations of a bridge crossing the River Glyde in Dundalk. Since then concrete technology has developed and with the advent of reinforced and...

Minimising the risk of deleterious alkali-silica reaction in Irish concrete practice.
November 1, 2005... Abstract National guidance on minimising the risk of alkali-silica reaction was first published in the Republic of Ireland in 1991. The introduction to practice of European Standard EN206-1 and the pending withdrawal of conflicting...

A study of the influence of slag alkali level on the alkali-silica reactivity of slag concrete.
November 1, 2005... Abstract Ground granulated blast furnace slag (ggbs), can reduce the alkali load in concrete, despite its relatively high alkali content. Most research has been devoted to the efficacy of slag with an alkali content of less than 1.0% and...

Obtaining progressive chloride profiles in cementitious materials.
November 1, 2005... Abstract The ingress of chloride into concrete is controlled by its absorption and diffusion characteristics. The authors have carried out an investigation to monitor the rate of ingress of chlorides during a 48-week cyclic wetting and...

Predicting moisture movement during the drying of concrete floors using finite elements.
November 1, 2005... Abstract Predictive methods for determining the point at which it is safe to apply floor coverings to concrete floors can save time and money for the client, contractor and the floor installer. The current standard states that impervious...

Influence of coarse aggregate on the permeation, durability and the microstructure characteristics of ordinary Portland cement concrete.
November 1, 2005... Abstract Reinforced concrete structures in marine and similar environmental conditions have to withstand severe exposures. Due to this, the mix design procedures have to be revised to include durability as a primary criterion along with...

Strength and drying shrinkage properties of concrete containing furnace bottom ash as fine aggregate.
November 1, 2005... Abstract The strength and drying shrinkage of concretes with the natural sand replaced with furnace bottom ash (FBA) at 0%, 30%, 50%, 70% and 100% by mass, were studied at fixed water-cement ratios (W/C) and fixed slump ranges. The...

Potential use of spent mushroom compost ash as an activator for pulverised fuel ash.
November 1, 2005... Abstract The utilization of pulverised fuel ash (PEA) as a replacement material for Portland cement has resulted in improved concrete properties. However, the pozzolanic activity of PFA is slow, resulting in poor strength development of...

The development of a non-linear numerical model to simulate the behaviour of reinforced concrete flat slabs in the vicinity of edge columns.
November 1, 2005... Abstract The development of a non-linear numerical model of reinforced concrete in the vicinity of edge columns is presented. The model uses a "stepped" grillage analysis that idealises the slab as an interconnected assembly of beam...

Identification of stiffness degradation in structures using wavelet analysis.
November 1, 2005... Abstract An approach for structural health monitoring (SHM) and damage detection using a wavelet based time-frequency technique is presented here. The characteristics of dynamic responses of structures are studied by wavelet analysis....
