RISEffect of Water-to-Cement Ratios on Performance of Concrete with Prewetted Lightweight Aggregates
Publisher: American Society of Civil Engineers
Abstract: Lightweight aggregates (LWAs), as a popular material for internal curing (IC), have been extensively utilized in internally cured concrete (ICC). This paper investigated the development of mechanical properties, restrained ...
Experimental Investigations on Early-Age Stress Relaxation and Cracking Behavior of Supersulfated Cement Concrete with Different Activator Proportions
Publisher: American Society of Civil Engineers
Abstract: As an alternative to ordinary portland cement (OPC), supersulfated cement (SSC) has better properties in terms of being environmentally friendly as well as durability in aggressive environments. Nevertheless, the research ...
Estimating Stress Relaxation and Cracking Potential of High-Strength Concrete Reinforced with Polyvinyl Alcohol Fiber at Early Age
Publisher: ASCE
Abstract: High-strength concrete (HSC) with a low water-to-cement (w/c) ratio always exhibits high shrinkage at an early age. Concrete with shrinkage that is subjected to restraint is prone to trigger harmful cracking, which facilitates ...
