river sand as fine aggregate and they adopt a special arrangement for the loading system for bond tests. The steel is of nominal diameter16 mm. The average compressive strength of concrete was 37 MPa and the aggregate used was 13 mm maximum size crushed stone and river sand. In this test it

USE OF DUNE SAND AS AN ALTERNATIVE FINE AGGREGATE IN USE OF DUNE SAND AS AN ALTERNATIVE FINE AGGREGATE IN CONCRETE AND MORTAR R. Sanjeevan 1, S. Kavitha2, 4T.C. Ekneligoda3 and D.A.R. Dolage 1,2,3,4 Department of civil Engineering, The Open University Sri Lanka INTRODUCTION River sand is the most widely used fine aggregate in civil engineering constructions in SriA Study on Dredged Sea Sand as an Optimum Replacement for of fine aggregate. The mix design have been done for M30 grade of concrete and the percentage of replacements 25%, 50%, 75%, and of M-Sand (Manufacture Sand) of concrete specimen for all the experiments is considered. As we all know our current scenario of increase in demand of fine aggregate leads to scarcity of river sand.

Importance of Gravel and Sand for Concrete | Concrete is made up of cement and water plus an aggregate composed of sand and gravel. The sand and gravel do more than act as filler, though. The size and amount of gravel added to a bag of concrete also determines the product's volume, strength, and durability.

Feasibility of Quarry Dust to Replace River Sand as Fine Feasibility of Quarry Dust to Replace River Sand as Fine Aggregate of Concrete R W C N Rajapaksha and H P Sooriyaarachchi Abstract: High cost and scarcity of river sand is one of the main problem faced by construction industry today. Use of substitutions like offshore sand in particular to replace river sand is on the rise.

How can sea sand be used in concrete? - QuoraConcrete is a mixture of cement, coarse aggregates, fine aggregates or sand and water. The approximate ratios of these components are as below: Based on the ratios and the anticipated cement consumption in the country, the expected requirement of

STRENGTH OF CONCRETE CONTAINING DIFFERENT TYPES OF FINE

"STRENGTH OF CONCRETE CONTAINING DIFFERENT TYPES OF FINE AGGREGATE" Sachin Balkrishna Kandekar, Amol Jagannath Mehetre, Vijayshree A. Auti Abstract— Common river sand is expensive due to excessive cost of transportation from natural sources. Also large-scale depletion of these sources creates environmental problems.An Investigation into the Use of Manufactured 02.06.2016· 1. Introduction. In many countries sources of natural sand for use as an aggregate in construction are becoming scarce as sand pits are exhausted and environmental legislation prevents dredging [1,2,3].This is driving the need to source alternative aggregates, such as those from construction and demolition waste.Brick Fine Aggregate and Ladle Furnace slag as aggregate (BFA) and ladle furnace slag (LFS) as alternative to natural river sand as fine aggregates in concrete. For this, cylindrical concrete specim ens of 100 mm x 200 mm size were made byM Sand Vs River Sand (Natural Sand)Though M Sand uses natural coarse aggregates to form, it causes less damage to the environment as compared to river sand. Harmful to the environment. Eco imbalances, reduce groundwater level and rivers water gets dried up. Price. M Sand price ranges from Rs.35 - Rs.45 per cubic feet in Bangalore.
