effects on durability of concrete by using manufactured sand
Many researches showed that manufactured sand is a best alternative for natural sand in terms of strength and durability and the concrete mix with 60% replacement has given good durable properties . Hudson, 1997, conducted a study using natural and crushed sand to compare the resistance and characteristics of concrete with high fine material [ 6 ].
Effect of Manufactured Sand on Durability Properties of ...
penetration test shows that chloride ion penetrability is high for concrete with natural sand while it is reduced using manufactured sand. They attribute this due to coarser stone size of manufactured sand resulting in better packing of particles. They suggest that 70% of manufactured sand in concrete is the optimum replacement for natural sand for better results. Experimental results of M.G. Shaikh et al. …

In the second phase of the study, another specimen of standard cube of (150 mm x 150 mm x 150 mm) was used to determine the compressive strength of concrete with artificial sand with full replacement and demolished concrete structure aggregates.
Properties of Concrete by Replacement of Natural Sand with ...
Over the time some investigations have shown that angular particles, rough surface of artificial sand influences the workability and finish ability in fresh concrete. The artificial sand have to satisfy the technical requisites such as workability, strength and durability of concrete and hence it has become necessary to study these properties in order to check the suitability and appropriate replacement level of artificial sand in comparison with the natural sand …
Use of Manufactured Sand in Concrete and Construction An ...
However, many people in India have doubts about quality of concrete / mortars when manufactured or artificial sand are used. Manufactured sand have been regularly used to make quality concrete for decades in India and abroad. Pune - Mumbai expressway was completely built using artificial/manufactured sand. Issues with Manufactured Sand
Strength and Durability Properties of Granite Powder Concrete
Both concrete made using artificial sand and natural sand are moderate to chloride permeability. In water absorption test we observed after 24 hours curing, the increase in weight of both natural sand and artificial sand blocks are less than 3% that means both concrete are low absorber hence concretes are good quality.
Durability of sea-sand containing concrete: Effects of ...
Optimum durability performance of the concrete is reached under these conditions: A3, B1, C4, D1, or; the sand is type A3, a desalted sea sand, the water/cement ratio is B1, 0.45, the curing time is C4, 180 d, and the water consumption per cubic meter is C4, 185.
Replacement of Natural Sand by Crushed Sand in the ...
Mar 01, 2017 · It is seen from their studies there a variation in strength enhancement of concrete made from artificial sand to encourage the use of locally available artificial sand promotes to study to check it suitable replacement percentage in the concrete.
Strength appraisal of artificial sand as fine aggregate in ...
tensile strength and durability studies of concrete made of quarry rock dust in varying proportions were higher than those of conventional concrete by using natural sand as fine aggregate. The workability of the concrete mixes decreased with an increase in percentage of stone dust. It indicates that water requirement is higher in such concrete
Use of sea-sand and seawater in concrete construction ...
Nov 30, 2017 · This stone presents a critical review of existing studies on the effects of using sea-sand and/or seawater as raw materials of concrete on the properties of the resulting concrete, including its workability, short- and long-term strength as well as durability.
