Summary
This study developed sustainable self-compacting concrete using sea water and sand for coastal construction. The resulting concrete demonstrated high strength, making it suitable for textile-reinforced structural elements.
Area of Science:
- Civil Engineering
- Materials Science
- Sustainable Construction
Background:
- Development of high-strength concrete for textile-reinforced structural elements.
- Utilization of local building materials for coastal construction sites.
- Assessment of self-compacting concrete properties using ordinary and sulfate-resistant cements.
Purpose of the Study:
- To develop and evaluate self-compacting concrete utilizing sea water and sea sand.
- To investigate the properties of concrete and textile-reinforced concrete made with local coastal materials.
- To assess the feasibility of using sustainable materials in load-bearing concrete structures.
Main Methods:
- Formulation of self-compacting concrete mixtures with ordinary and sulfate-resistant cements.
- Testing of concrete properties including compressive strength, flexural strength, and drying shrinkage.
- Evaluation of textile-reinforced concrete performance under uniaxial tensile load.
Main Results:
- Sea concrete achieved a 28-day compressive strength of 72 MPa and flexural strength of 9.2 MPa.
- Control concrete exhibited a 28-day compressive strength of 69.4 MPa and flexural strength of 11.1 MPa.
- Sea concrete showed an 18% higher drying shrinkage compared to control concrete at 28 days.
Conclusions:
- The use of sea water and sea sand in self-compacting concrete is viable for coastal construction.
- Carbon textile reinforcement effectively engaged after crack formation in both control and marine concrete.
- Combining sea-derived materials with low-CO2 cement and textile reinforcement offers a sustainable solution for structural concrete.

01:22Effect of Sea Water on Concrete
288
Concrete exposed to seawater can undergo degradation like the dissolution of ettringite and gypsum, increasing the material's porosity and decreasing its strength. In contrast, the crystallization of salts within the concrete's pores can cause expansion, particularly above the waterline where evaporation occurs. Nonetheless, this expansion only happens when seawater, enabled by the concrete's permeability, manages to infiltrate the structure.

01:22Fiber Reinforced Concrete
102
Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...

01:25Reinforcements in Concrete
113
Reinforced concrete is a composite material used extensively in construction, combining the compressive strength of concrete with the tensile strength of steel. This synergy is essential as concrete, while excellent at resisting compression, is weak under tension. Steel bars, or rebars, are embedded in the concrete to handle these tensile forces. The choice of steel is strategic; it shares a similar coefficient of thermal expansion with concrete, which ensures uniformity in response to...

01:14Testing Water Quality
136
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

01:28Effects of Air-entrainment in Concrete
107
Air entrainment in concrete significantly enhances the material's durability, especially in environments subjected to freeze-thaw cycles. Introducing small air bubbles into the concrete mix acts as internal voids that accommodate the expansion of water when it freezes, thereby alleviating internal stress and preventing structural cracks. This function is crucial in climates with significant freezing and thawing, as it protects the concrete from repeated stresses that could lead to premature...

01:20Prestressed Concrete
174
Prestressed concrete is a construction technique designed to enhance the strength and durability of concrete structures. This method involves the application of a pre-set tension to high-strength steel strands used as reinforcement before the concrete is subjected to its working loads. The primary aim of prestressing is to place the concrete in a state of compression, in order to counteract the tensile forces it will experience in service. This pre-compression helps prevent crack formation in...
