From the comparison of figures of Table 3 & 4, it is observed that the sieve analysis replacement of river sand by crushed brick grit was used. Figure 2 Drying Shrinkage Test . Using the mortar paste, prism measuring 25 mm x 25 mm x 275 mm size was prepared and
Manufactured Sand (M-sand) Manufactured sand (M–Sand) is a substitute for river sand for concrete construction.Manufactured sand is produced from hard granite stone by crushing.The crushed sand is cubical with grounded edges, washed and graded to as a construction material.The size of the manufacture M-Sand is less than 4.75 mm.
This report deals with the comparison of the materialistic differences between sea and river sand. Chloride content in sea water X-ray diffraction pattern of crushed river sand powder
The parameters of investigation include, type of aggregate (River sand, crushed stone dust and foundry sand), mix proportion (1:1 and 1:2), size of fine aggregate (4.75 mm down, 2.36 mm down, and 1.18 mm down), and age of curing (28 days). A total of 225 specimens were cast and tested in this study.
But when river sand is used in concrete the permeability of concrete is less poor as compared to river sand. It has more water absorption 2 to 4 %. Whereas water absorption of river sand is less 1.5 to 3%. Drawbacks of M Sand. Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the
Quality. We can expect a good quality of material since it is produced from a factory. The possibility of quality is low because sometimes other types of sand can be mixed with River Sand. Density. The density of M Sand – 15540 to 1650 Kg/Cum. The density of River Sand – 1400 to 1700 Kg/Cum. Impact on the Environment.
The data explored the assessment of the quality of river sand as an aggregate in replacement of crushed stones which are widely used by majority of manufacturers in production of interlocking stones. Experimental tests carried out on river sand and crushed rock as aggregates include: Grain size dist …
Crushed rock sand (CRS) did not present harmful compounds and the CRS filter bed did not negatively affect the quality of the filtered water (turbidity, pH and electrical conductivity). Filtration run length, turbidity removal and head loss accumulation were similar in both the CRS and the natural sand river (NRS) filters.
Abstract This study compared the physical and mechanical properties of river sand concrete with quarry dust concrete. The constituent materials were batched by weight. The water-cement ratio and mix ratio selected for the experimental investigation were 0.55 and 1:2:4, respectively. The specimens were cured for 7, 14, 21 and 28 days. Slump, density and compressive strength tests were carried out.
The parameters of investigation include, type of aggregate (River sand, crushed stone dust and foundry sand), mix proportion (1:1 and 1:2), size of fine aggregate (4.75 mm down, 2.36 mm down, and 1.18 mm down), and age of curing (28 days). A total of 225 specimens were cast and tested in this study.

River Sand vs Manufactured 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
Manufactured Sand (M-sand) Manufactured sand (M–Sand) is a substitute for river sand for concrete construction.Manufactured sand is produced from hard granite stone by crushing.The crushed sand is cubical with grounded edges, washed and graded to as a construction material.The size of the manufacture M-Sand is less than 4.75 mm.
Nowadays development of infrastructures is becoming number one priority in the world, particularly in the developing countries. So there are great demands within the construction industries for river sand as fine aggregate used in the production of concrete. This has created a very difficult situation; the cost of river sand has increased and also there is great fear from environmentalist and
The solid performance of the artificial sand is slightly worse than that of the river sand, but it still can meet the international sand standard. However, for the construction that is often subjected to frictional impact, the lime-sand ratio of the concrete, the crushing index and the stone powder content of the sand should be controlled.
This paper describes the effects of high temperatures on the strength characteristic of crushed limestone sand concrete (CLSC). To compare, natural (river) sand concrete (NSC) and CLSC specimens were exposed to the three different high temperatures. Visual color-change and weight loss were also carefully examined through the tests. The test results indicated that the decreasing rate of
The parameters of investigation include, type of aggregate (River sand, crushed stone dust and foundry sand), mix proportion (1:1 and 1:2), size of fine aggregate (4.75 mm down, 2.36 mm down, and 1.18 mm down), and age of curing (28 days). A total of 225 specimens were cast and tested in this study.

Two different sands have been used in this study: the first one is a river sand (RS) (Fig. 1a) from the river M’zi (around the city of Laghouat) and the second one is a crushed sand (CS) (Fig. 1b) brought back from local quarry waste, near the city of Laghouat.Their particle size distributions are shown in Fig. 2.It should be noted that “CS” is a waste of local crushing aggregates that
Whereas the slump of river sand is more as compared to crushed sand. 13: It does not contain any Marine Products. whereas river sand may contain Marine Products such as grass, algae, Clay lumps, bones, shells, mica etc. which are harmful to properties of concrete. 14: The bulk density is 1.75 gm/cm 3. Whereas the bulk density of river sand is 1
B. Balapgol, S. Kulharn, K.Bajoria (2002), investigated the use of crushed sand as fine aggregates along with fly ash in concrete. They says that a combination of fly ash and crushed sand yield a far superior concrete mix than crushed sand alone. Hadassa Baun and Amnon Katz (2009) studied the percentage of fines in crushed sand and its

Copper Slag – Filtered Sand; Sea Sand, Slag Sand; Crushed Waste Glass; Recycled Aggregate/C&D Waste Aggregate etc. The demand for alternative materials of river sand for making concrete is increasing day by day as river sand cannot meet the rising demand of construction sector. It is fact that the river sand takes millions of years to form.

Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 9.5mm sieve. For concrete sand fineness modulus range is 2.3-3.1. Among these ingredients river sand is commonly used as fine aggregate in concrete which is becoming scarce and hence
