Compressive Strength

Research Trends:

1. Graphene Oxide Reinforcement in GFC: Wang et al. (2023) focus on the physical and mechanical properties of GFC, particularly emphasizing the reinforcement effect of graphene oxide. This study highlights the improvement in compressive strength, water resistance, and porosity of GFC due to graphene oxide addition.
2. Polypropylene and Polyolefin Fiber Reinforcement: Smaoui et al. (2023) explore the effects of polypropylene and polyolefin fibers in concrete, investigating their impact on compressive strength under various environmental conditions, such as acidic, chloride, and sulfate environments. The research indicates that polyolefin fibers generally exhibit a more pronounced reinforcing effect than polypropylene fibers.
3. Ambient Cured Fiber-Reinforced Geopolymer Concrete: Reed, Lokuge, & Karunasena (2014) discuss the properties of fiber-reinforced geopolymer concrete with ambient curing, primarily focusing on the compressive and tensile strength enhancements through fiber integration.

Strengths and Weaknesses:

1. Comprehensive Analysis: Wang et al. and Smaoui et al. provide a detailed analysis of the mechanical properties of concrete with different fibers, offering a comprehensive understanding of the materials’ performance in various conditions.
2. Limitations in Scope: While the studies cover a broad range of tests, they may have limitations in addressing long-term durability and real-world application scenarios, as noted by Reed et al. (2014).
