The percentage of sand in sand-lime bricks varies from 88 to 92 per cent. Hence the properties of sand-lime bricks are mainly governed by the characteristics of sand. For getting sand-lime bricks of good quality, the sand should be well-graded and it should be free from impurities such as clays, organic matter, rock minerals, soluble salts, etc.
Iron slag (I-sand) generated as a by-product in iron and steel industries, is usually disposed by delivering to landfills. Effective utilization of iron slag in reinforced concrete could be an interesting method for the aforementioned waste disposal with the added advantage of conservation of natural resources and as an economically viable alternative.
• The characteristics of river sand would improve the workability of concrete and mortar compared to the use of alternatives such as crushed rock fine. • The use of river sand would, for a given workability requirement, reduce the water demand and/or superplasticizer demand, and thus allow a lower
Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
Recycled sand and aggregate from C&D waste is said to have 10-15 per cent lesser strength then normal concrete and can be safely used in non-structural applications like flooring and filling. Delhi already has a recycling unit in place and plans to open more to handle its disposal problem.
Manufactured sand is an alternative for river sand. Due to fast growing construction industry, the demand for sand has increased tremendously, causing deficiency of suitable river sand in most part of the word. Due to the depletion of good quality river sand for the use of construction, the use of manufactured sand has been increased.
5 alternatives to concrete: Mogu, Finite, Corcrete, CarbonCure and Made of Air . Chatham House recently reported that approximately eight per cent of the world's annual carbon dioxide emissions is due to concrete production.The process used to create the cement requires a high-temperature kiln which contributes to CO2 emissions. In light of this report, it is vital to not only use …

Infographic: Finding alternatives to using sand in construction. Sand is the second-most extracted resource on Earth after water. However, it is not infinite. For it to be sustainable, the world should consider avoiding concrete, of which sand is the key component, and use alternative building materials or improve our recycling systems.
Due to the depletion of good quality river sand, M-Sand is identified as an alternative to River sand. M-sand stands for manufactured sand. It is manufactured in industries/ quarries by crushing rocks, quarry stones or larger aggregate pieces into sand sized particles. For various construction works, different suitable grades of M-sand are used.
The supply of construction-grade sand is dwindling worldwide. This type of sand is stripped from beaches and riverbeds, but because of the heavy use, the supply is diminishing rapidly. Desert sand, on the other hand, is plentiful. This sand is not used in construction, as its grains are too smooth and fine to bind together for building materials.

The percentage passing 150 microns of manufactured sand is relaxed to 20% (while that of natural sand is limited to 10%). As per design and economics, crushed sand can be used to partially or fully replace river sand from a concrete mix. The Availability of crushed sand is not a concern as it can be manufactured from rocks in any season.
On a comparative level, artificial sand is a very close match to building sand mostly because building sand tends to be more widely used than any of the other types. In terms of how artificial sand is made, generally, it is produced through crushing up basalt rock or granite rock and due to this is normally greyish in colour.
The exploitation of river sand from the river beds by large growing construction activities has resulted in the exploration of a substitute material for river sand i.e. Manufactured Sand or M-Sand. M Sand is an eco-friendly and affordable alternative to river sand. M-Sand is manufactured by crushing rocks, quarry stones into sand-sized particles.
The modern world is built on concrete. But the building material has remained pretty much the same for hundreds of years: a mix of sand, gravel, cement, and water.In a paper published in the journal Matter, researchers present a recipe for a new living, reproducing building material that has cement-like strength.. The material offers a sustainable alternative to modern building materials.
Using a variety of kiln dry sand blast cleaning media or grit, such as hard Garnet and aluminium oxide, mixed with compressed air to clean off and strip paint and other unwanted coatings from hard woods and metals and some stone, it is now much more effective and safe to use blast cleaning methods and blast media to carry out these tasks.
