RISSimulation of Thaumasite Sulfate Attack on Portland Cement Mixtures Using Synthesized Cement Phases
Publisher: American Society of Civil Engineers
Abstract: In this work, a simulation of thaumasite sulfate attack on portland cement mixtures was performed, using synthesized cement phases. Three model systems containing C3S, C3A, and alkali sulfate (CaSO4, Na2SO4, and K2SO4, ...
Influence of Sulfates on Chloride Diffusion and Chloride-Induced Reinforcement Corrosion in Limestone Cement Materials at Low Temperature
Publisher: American Society of Civil Engineers
Abstract: An ordinary portland cement and two portland limestone cements [15 and 35% weight-to-weight ratio (w/w) limestone content] were used for concrete and reinforced mortar specimens preparation. The specimens were exposed to ...
Exposure of Mortars Modified with Rubber Aggregates and Polymer Admixtures to Acid Environments and Elevated Temperature Conditions
Publisher: American Society of Civil Engineers
Abstract: The aim of the present paper was to study the effect of incorporating rubber aggregates and acrylic or EVA polymers on the properties of cement mortar exposed to acid (HCl,
Thermal Behavior of an Intumescent Alkaline Aluminosilicate Composite Material for Fire Protection of Structural Elements
Publisher: American Society of Civil Engineers
Abstract: The behavior of a composite material, consisting of metakaolin-based alkaline aluminosilicate binder, granules of the same initial composition used as a swelling agent, and calcium carbonate, was studied during firing in ...
