RISEvaluation of Particle Effects in Portland Cement Systems
Publisher: American Society of Civil Engineers
Abstract: Various filler materials were evaluated to identify and differentiate chemical reactions from physical particle reactions during hydration within a portland cement system. Laboratory teasting included solubility within a ...
Sulfate Durability of Type IL-Slag Blended Cement under Different Curing Exposures
Publisher: American Society of Civil Engineers
Abstract: AbstractTo improve concrete sulfate durability, supplementary cementitious materials (SCMs)
like slag, fly ash, and silica fume have been widely used as partial replacements
for ordinary portland cement. This study examines ...
Measuring Rock Strength While Drilling Shafts Socketed into Florida Limestone
Publisher: American Society of Civil Engineers
Abstract: The focus of this research was the real time assessment of rock strength during drilled shaft installations in Florida. Measures of unconfined compressive strength, a function of rock strength used commonly in shaft design, ...
Direct Tensile Performance of Fiber-Reinforced High-Strength and Ultrahigh-Performance Concrete with Varied Curing Conditions
Publisher: American Society of Civil Engineers
Abstract: AbstractDirect tension tests were conducted on fiber-reinforced concretes with strengths ranging
from high-strength to ultrahigh-performance concrete (UHPC) (83–165 MPa or 12–24 ksi)
to determine how mixture ...
