Use of sea sand as fine aggregate in concrete making Dr Arabinda Bandyopadhyay , Chief Technologist (PhD – Mineral Engineering), CDE Asia Ltd Concrete is a mixture of cement, coarse aggregates, fine aggregates or sand and water
the sea sand pumped from a distance of about ten kilometers is very suitable for building construction industry This study is to experiment the suitability to use beach/sea sand as a substitute for river sand as fine aggregate for concrete Keywords: Concrete, Sea sand and Fine aggregate 1 INTRODUCTION
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
— In the present work, literature on the use of sea sand as replacement of fine aggregate has been studied The chloride content in reinforced concrete according to various codes has been evaluated the chloride removal method have been studied This
Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar Types of aggregates include Coarse aggregate and fine aggregate
Nov 14, 2013· Types Of Fine Aggregates Sand Stone dust Cinder Surkhi 12 Sand The first type of fine aggregate is Sand Sand is little particles of silica Larger particles are categorized as gravel; smaller particles are categorized as silt or clay 13 Types of Sand Pit Sand River Sand Sea Sand 14 Pit Sand Sand from a pit, as distinct from river or sea sand
Apr 28, 2013· 7(1) Fine Aggregates:Aggregates whose particles passthrough 475 mm IS sieve are termedas fine aggregat Most commonlyused fine aggregates are sand (pit orquarry sand, river sand and sea sand)and crushed stone in powdered form,how ever some times sukhi and ash orcinder are also used 7 8(a) Sand:It consists of small angular orrounded grains .
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.
