RISStudies on Several Factors Affecting Hydration and Properties of Lime-Pozzolan Cements
Publisher: American Society of Civil Engineers
Abstract: This paper investigates effects of several factors such as lime content and the types of lime on water requirement, initial porosity, strength development, pozzolanic reaction rate, and pozzolanic reaction chemistry of ...
Steel Slag—Its Production, Processing, Characteristics, and Cementitious Properties
Publisher: American Society of Civil Engineers
Abstract: Steel slag is a byproduct from either the conversion of iron to steel in a basic oxygen furnace, or the melting of scrap to make steel in an electric arc furnace. This paper reviews the production, processing, and ...
Corrosion of Glasses and Expansion Mechanism of Concrete Containing Waste Glasses as Aggregates
Publisher: American Society of Civil Engineers
Abstract: Expansion and cracking of portland cement concrete containing glass aggregates have been known for decades. Traditional alkali-silica reaction and expansion mechanisms are being used to explain the reaction and expansion ...
Carbonated Ladle Slag Fines for Carbon Uptake and Sand Substitute
Publisher: American Society of Civil Engineers
Abstract: The possibility of using a carbonated ladle slag as a fine aggregate in concrete was investigated. The slag was treated with carbon dioxide to reduce the free lime content while binding gaseous
Review of Thaumasite Sulfate Attack on Cement Mortar and Concrete
Publisher: American Society of Civil Engineers
Abstract: Durability is one of the most important considerations regarding the design of new concrete structures in aggressive environments. Thaumasite sulfate attack (TSA) is one durability consideration. This paper reviews the ...
Effects of Loading Rate and Temperature on Pullout Response of Basalt Textile–Reinforced Concrete
Publisher: ASCE
Abstract: The pullout response of basalt textile embedded in cementitious matrix specimens was investigated under different loading rates and temperatures. Two types of specimens, basalt single yarn and basalt textile, were tested. ...
Effect of Inorganic Surface Treatment on Air Permeability of Cement-Based Materials
Publisher: American Society of Civil Engineers
Abstract: Permeability is an important indicator of durability of cement-based materials. Surface treatment is a simple method to reduce the permeability of cement-based materials. This paper evaluates the air permeability of ...
Statistical Damage Constitutive Model for Rocks Considering Residual Strength
Publisher: American Society of Civil Engineers
Factorial Design Method for Designing Ternary Composite Cements to Mitigate ASR Expansion
Publisher: American Society of Civil Engineers
Abstract: Supplementary cementitious materials (SCMs) have been successfully employed in binary or ternary cement blends to mitigate alkali-silica reaction (ASR). The determination of composition of binary or ternary composite cement ...
Effects of Deicing Salts on the Scaling Resistance of Concrete
Publisher: American Society of Civil Engineers
Abstract: The scaling resistance of concrete with strength grades of 30 MPa (C30) and 50 MPa (C50) subjected to different types (A and B) and concentrations (3, 5, and 20%) of deicing salt solution were studied using an accelerated ...
