Masonry is among the oldest and widespread construction materials, used to build structures traditionally, both in North America, and worldwide as well. Most of the historical buildings have been built with pre-Portland cement mortar. A large number of existing masonry buildings in Canada have...
The present study has focused on the effects of Powdered Activated Carbon (PAC) in fly ash on the air-entraining admixture demand and consequent properties of concrete. An extensive laboratory test program was completed during this investigation. Three series of mixes were designed to evaluate...
Effect of Cellulose Nanocrystal Particles on Rheology, Transport and Mechanical Properties of Oil Well Cement SystemsDownload
The increase in oil consumption during the past few decades, coupled with oil/gas extraction from shale in the recent years has increased drilling and cementing demands. Well cementing operation is one of the most crucial and important steps in any well completion. However, since it takes place...
The most common detrimental processes that lead to reduction in durability in reinforced concrete elements are shrinkage, sulphate attack and chloride attack. Shrinkage is a dimensional instability chiefly caused by a loss of moisture in the hydrating cement paste. Soluble sulphate ions take part...
The durability of concrete is one of its most important properties and has been an attractive subject for research in recent years. One of the criteria that affect concrete durability is permeability. Transport processes in concrete have been investigated for several decades. However, the...
This study assesses the suitability of four sectional shear methods for predicting the shear capacity of reinforced concrete members which do not comply with S6-06 Section 14 stirrup spacing and area requirements. The results of the evaluations indicate that the sectional shear provisions in...
Experimental Study and Numerical Modeling of Diffusion and Reaction Behaviour in Cement-based Composites under Sulphate AttackDownload
This thesis describes several approaches evaluating the resistance of cement-based composites under adverse external-sourced sulfate attack. The conventional approach of evaluation by means of measuring expansion was discussed in comparison with the sulfate diffusion, which was quantified as a...
This study describes the strength, toughness and strain-rate sensitivity of fibre-reinforced cement-based foams subjected to variable loading rates. Drop-weight impact tests were conducted on beams with cast density between 475 - 1200 kg/cu.m. The study shows that under quasi-static loading, the...
With growing concern over global warming and greenhouse gas emissions, research must be undertaken to reduce the environmental footprint of buildings. Cellular concrete provides good strength to weight ratios and good thermal insulation because of its cellular structure. This makes it suitable...
Hooked end steel fibers were included between 0~1% by volume to provide enhanced shear resistance to three different types of steel fiber reinforced concrete (SFRC) namely, a regular concrete mix, a lightweight aggregate mix and a high strength mix. The test results at the material scale showed a...
