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.
27-8-2018· This video explains about sand used in construction, the sources of sand and comparison between river sand, pit sand and sea sand.
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...
Keywords: Concrete, Sea sand and Fine aggregate. 1. INTRODUCTION . Sand is a unique raw material for the construction industry at present, but contractors say that they have to spend more allocations for obtaining bulk loads of sand for their construction work.
obtained with the partial replacement of river sand with 20% CGF, as against values of 35.00N/mm2 and 1.75N/mm2 obtained with the use of river sand as fine aggregate. Based Experimental Investigation on the Effect of Replacement of Sand by Quarry Dust in Hollow Concrete Block for Different Mix Proportions
Demand for concrete in developing countries is high; it’s ingredients cement, fine and coarse aggregate are equally in need in immense quantity. High degree of consumption leads to depletion of natural resources like Natural River Sand causes

Sand passing through the 1.5875 mm sieve is called fine sand. Fine sand is mostly used in plastering works for better finish. Classification based on grain size:-Based on grain size sand is classified into Very fine sand, fine sand, medium sand, coarse sand and very coarse sand the grain sizes of different types of sand are stipulated below:

Fine aggregate; Coarse aggregate; Fine Aggregate. When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it called as fine aggregate. Natural sand is generally used as fine aggregate, silt and clay are also come under this category. The soft deposit consisting of sand, silt and clay is termed as loam.
