WFS replacement rates were 15 30 and 45 by weight of the manufactured sand and that of GGBS was 30 constant by weight of cement. Obligatory performance tests were conducted as per Indian standards which included compressive strength water absorption and abrasion resistance.
crusher sand crusher dust stone dust etc. The use of manufactured sand has increased due to the nonavailability of river sand which is regulated and banned from use in most of India. Recently the North Western states and Delhi went through a similar situation when the court ordered a stay on the use of river sand.
Based on economic analysis and results of tests river sand replaced with 20 CGF is recommended for use in the production of concrete for use in rigid pavement. Conservation of river sand
The natural river sand was the cheapest resources of sand. However the excessive mining of rive bed to meet the increasing demand for sand in construction industry has lead to the ecological imbalance in the state. Now the sand available in the riverbed is very coarse and contains very high percentage of silt and clay. All Agrigates 12mm 20mm 40mm
In India attempts have been made to replace river sand with quartzite rock dust. The successful utilization of quartzite rock dust as fine aggregate would turn this waste material that causes disposal problem into a valuable resource. The utilization will also reduce the strain on supply of natural fine aggregate which will also reduce
Usage of MSand can drastically reduce the cost since like river sand it does not contain impurities and wastage is NIL. In International Construction Scenario no river sand is used at all only sand is manufactured and JOURNAL OF ARCHITECTURE TECHNOLOGY Volume XI Issue II 2019 Issn No € Page No 6

River sand is costly due to transportation large scale depletion of resources and enforcement regulations. Quarry dust can be used as an alternative to the river sand. Cost analysis shows that there is 40 savings if quarry dust is used instead of sand. 2000 has done a study on100 replacement of sand by quarry dust in concrete
The 60 replacement showed an increase in strength of about 20 and other changes to an order of minimum in both the grades. The durability study is conducted by treating specimens for 30 days with 5 concentrated Hydrochloric Acid and the concrete mix with 60 replacement has given good durable properties. ENVIRONMENTAL IMPACT OF SAND MINING
