21-9-2017Concrete has been used for ages as a building material Concrete when freshly mixed can take nearly any form and shape but dries and cures to rock-like hardness Concrete is a mix of coarse rock fine sand and a water-activated substance that binds the rock and sand together In the modern era that binder is
China has used more concrete in the past two years than the United States over the last 100 years For the construction industry respectively for concrete only sea sand can be used Desert sand grains are ground to round by the wind and the cement cannot adhere to it
Sea sand can be used in concrete when regular sand is not available The main worry is about the durability related properties as the sea sand has large amount of salts adhered on the its surface Just water washing may not remove all deleterious materials firmly adhered on to the surface

I find an answer !!! amazing one!Yes we can!Both sea water and sea sand can be used for plain concrete no steel reinforcementwe can wash the sea sand then use it but it will be more expensive than the others Also we can get benefits from this CONCLUSIONS of a research was done by japanese scientist after tests for20 years
Concrete has a very low coefficient of thermal expansion and shrinks as it matures All concrete structures crack to some extent due to shrinkage and tension Concrete that is subjected to long-duration forces is prone to creep Tests can be performed to ensure that the properties of concrete correspond to specifications for the application
Usage of sea sand for concrete development is the possible alternative for river sand and avoids the excessive sand mining which may cause ecological and environmental problems Sea sand is not used in concrete since it contains chloride ions which can corrode steel
Concrete Sand Concrete sand is and aggregate sand usually composed of either gneiss trap rock limestone or granite This specific type of sand is normally crushed at the quarry and then washed and screened for quality This process will make sure that there are no large rocks within the material
Use of sea sand as fine aggregate in concrete making Dr Arabinda Bandyopadhyay Chief Technologist (Ph D – Mineral Engineering) CDE Asia Ltd Concrete is a mixture of cement coarse aggregates fine aggregates or sand and water The approximate ratios of these components are as below
research on dredged sea sand as a fine aggregate in concrete to reduce the demand on fine aggregate in construction industries Comparative study of M-sand river sand and dredged sea sand has been done The dredged sand which is used for the study and testing is dredged to increase the sea
If a civil engineer goes though the procedure of chloride penetration test in concrete/RCC he can answer the question Sea/beach sands contain more NaCl which can bring down the structure life to5 years or even less if the weather is humid

Sand (primarily silica) is used in construction as a component in various materials like concrete mortar etc Definitely the salts adsorbed (dissolution might not actually occur) on sand are going to affect the durability in reinforced concrete
Ultra-high-performance concrete is typically defined as an advanced cementitious material that has a compressive strength of over 150 MPa and superior durability This article presents the development of a new type of ultra-high-performance concrete namely ultra-high-performance seawater sea-sand concrete
Concrete is probably the most important building material today and is used as an alternative for brick/wood since the Roman Egyptian times It is composed of cement stone[gravel] sand and water which is a key ingredient that hardens the concrete When reinforced with steel bars it
However desert sand has little use the grains are too smooth and fine to bind together so it is not suitable for the making of for instance concrete The start-up Finite founded by researchers from Imperial College London created a material composite made with desert sand that serves as a more sustainable alternative to concrete
Concrete rubble should be recycled to avoid using aggregates at least for low-quality uses Recycling glass bottles would also reduce sand consumption Also substitutes for sand are available Quarry dust could be used to replace sand in general concrete structures
