• River sand is used in the construction industry mainly for concrete production and cement-sand mortar production. • River sand is obtained by dredging from river beds. It has the major characteristics that since it has been subjected to years of abrasion, its particle shape is more or less rounded and smooth, and since it has been subjected to years of washing, it has very low
M Sand: River Sand: Process. Manufactured in a factory. Naturally available on river banks. Shape. Angular and has a rougher texture. Angular aggregates demand more water. Water demand can be compensated with cement content. Smoother texture with better shape. Demands less water. Moisture Content. Moisture is available only in water washed M Sand.
Stone dust is a waste material obtained from crusher plants. It has potential to be used as partial replacement of natural river sand in concrete. Use of stone dust in concrete not only improve
The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and
04.02.2015· New type of crushed sand to replace natural sand in concrete production. The availability of natural sand for concrete production is facing challenges, while the so-called waste stockpiles at aggregate crushing areas are causing problems for producers. This means that the industry has a huge need to solve this challenge by finding suitable
23.10.2018· In International Construction Scenario, no river sand is used at all, only sand is manufactured and used, which gives superior strength and its cubical shape ensures significant reduction in the cement used in the concrete; Eco-Friendly M-Sand is the only alternative to river sand. Dredging of river beds to get river sand will lead to environmental disaster like ground water depletion, water
Manufactured sand is far more better than river sand. I did a project on comparison of concrete made of M-sand and river sand. Advantages of M-sand are: 1. 100 % replacement to natural sand and it is one of the byproduct of aggregates 2. No scarci
Hello The sand as a fine aggregate used in concrete does not have any substitute at all. However, if you ask me whether there is any substitute for the River sand ? The answer is : Yes. Certainly. The crushed sand is being used as a good substitut

While M-Sand is sold for Rs 700 to 900 per tonne, river sand costs Rs 1200 to 1400 per tonne," Kumar pointed out. Considering all these factors, organisations like GMR and L&T Metro Hyderabad Metro Rail Limited have been extensively using M-Sand for their projects in the city, he added. There are nearly 84 M-Sand manufacturing units in Hyderabad and neighbouring Ranga Reddy, Medchal, Yadadri
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. Illangoan.R [2000] [1] has done a study on replacement of sand by quarry dust in
river sand replacement of crusher sand - ellegisoft. Experimental Investigation on the Effect of Replacement. obtained with the partial replacement of river sand with 20% CGF, as against values of 3500N/mm2 and 175N/mm2 obtained with the use of river sand as fine aggregate Based Experimental Investigation on the Effect of Replacement of Sand by Quarry Dust in Hollow Concrete Block for
Partial replacement of sand with this dust will make good concrete that is well desired in Quarry dust has been proposed as an alternative to river sand that gives additional benefit to cement during construction. 5. Consumption reduces the pollution in environment. In areas where constructors use this dust, there is a significant reduction of air pollution by the dust. Quarry dust is very

Availability of good quality sand for construction has been a burning issue in Kerala for the last several years. On one hand, the brittle environmental balance of the State is threatened by illegal sand mining from rivers, at the same time, restrictions on sand mining has resulted in inadequate availability of good quality sand and has become one of the biggest hindrances of growth and

Since 1975 River Sands have manufactured a variety of quality graded sands and gravel (filter media) for the water filtration and construction industries both here in Australia as well as overseas. Unlike many of our competitors, when you purchase your filter media from River Sands, we will guarantee that your filter media is processed to the tightest spec every time - thereby ensuring the
as a good substitute for natural river sand giving higher strength at 50% replacement. Index Terms- Concrete, quarry dust, construction materials. It is conventional that sand is being used as fine aggregate in concrete. For the past two years, the escalation in cost of sand due to administrative restrictions in India, demands comparatively greater cost at around two to three times the

This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering. Three masonry wall panels of dimensions 1 × 1 m were plastered.
