This paper ... emissions and construction cost in a project using this concrete on an isolated island, and methods of its application to reinforced concrete structures.
The content of impurities in sea sand was measured in accordance with JGJ206-2010. The silt, sulfide, and light component contents of sea sand are similar to those of river sand, whereas the chloride and shell contents of sea sand are much higher than those of river sand. The gradation of sea sand particles was measured in ac-

This study presents an experimental investigation on self-compacting concrete (SCC) with fine aggregate (sand) replacement of a Quarry Dust (QD) (0%, 25%, 50%, 75%, ) and addition of mineral admixtures like Fly Ash (FA) and …
The use of seawater sea sand concrete (SSSC) and fiber-reinforced polymer (FRP) has broad application prospect in island and coastal areas. However, the elastic modulus of FRP reinforcement is obviously lower than that of ordinary steel reinforcement, and the properties of SSSC are different from that of ordinary concrete, which results in …
Fig. 1 highlights the increase in research interest on the topic of seawater-mixed concrete and concrete exposed to seawater, in the last few decades. The result of an article search across research databases with the string 'concrete and seawater', includes articles related to concretes exposed to seawater, concretes cured with …
As is well known, the gradation of aggregates has different effects on the fluidity and strength of concrete. In order to ensure the quality of SWSSC, JGJ206-2010 [17] specifies the limit value of aggregate particle size distribution. Gutt [34] believed that the geological origin of sea sand is similar to that of sand and stone used in ordinary …
The durability of a concrete structure is affected by temperature cycles that occur during the structure's service life. This paper presents an experimental and theoretical study of the mechanical properties of seawater sea-sand concrete when exposed to temperature variations. By using compressive tests on cylindrical concrete specimens, …

Advantages of Sea Sand. Sea sand particles are rounded or cubical, same as river sand. Grading of the sea sand is finer than the river sand. It does not contain silt or organic materials. Readily available though they need to be cleaned. Material grading and its consistency are added benefits. Mining can be done at a reasonable cost. Countries ...
Cellular Lightweight Concrete (CLC), also referred to as ed Concrete, stands out as a crucial cement variant in construction due to its manifold benefits and versatile applications, surpassing conventional concrete. Its composition involves a blend of Portland concrete, sand (with or without fly ash), and a stable .
Sand gradation are fine as well. 2.2. Preparation. It is widely accepted that the chloride content has a notable effect on the corrosion of ordinary steel in reinforced concrete [15].By using accelerated corrosion testing and changing the Cl − content in sea-sand, Dias et al. [16] showed that steel reinforcement corrosion became significant …
Dr. Tran Tuan Hiep (Vietnam) Researching on using sea sand to produce cement concrete for road pavement construction The strength of cement concrete using sea sand is less than traditional cement concrete using river sand from 4 - 10%. Strength of cement concrete using sea sand can reach 30 – 35 N/mm2 meeting requirements of concrete …

The increasing demand for river sand, driven by infrastructure development, poses environmental challenges. The study aims to address the depletion of river sand by integrating sea sand as a fine aggregate in the production of Self-Compacting Concrete (SCC) through a Systematic Literature Review. Furthermore, it includes an in-depth …
and flooding. By using the abundant sea sand is one of the alternatives in the investigation of this concrete brick. River sand will be replaced with abundant sea sand in accordance with a specified percentage. The percentage of the abundant sea sand to replace with the river sand is 5%, 10%, 15% and 20%. In addition, a size of concrete
For marine and coastal engineering, construction resources have become scarce due to a limited local supply. Sea sand geopolymer-based recycled concrete (SSGRC) is an innovative cementitious material known for its eco-friendly benefits and corrosion resistance. This study explores the mechanical properties of SSGRC. The …
