Today researchers world over are in continuous search for the alternatives to river sand. Fine aggregate is one of the important constituents of concrete. River sand is becoming very scarce and sand mining from rivers has become ...

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.

When 30% of sand replaced by demolished brick masonry aggregates, a steady increase in Compressive strength and split tensile strength of mortar was observed. Modulus of elasticity of mortar ...
Read More2017-11-30 The lack of river sand has led to the use of sea-sand and crushed stone fines in many countries, with the use of sea-sand in the UK being an example .More than 90% of the world’s dredged sea-sand has been used as a raw material in the construction industry, with over 45% of the dredged sea-sand being used as fine aggregate for concrete . Fig. 2 illustrates the situations of sea-sand ...
Read More-The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete. Quarry dust, a by-product from the crushing process during quarrying activities is one of such materials.
Read More2019-7-18 Posted on July 18, 2019. Concrete is a mixture of cement, gravel, sand, water and a range of aggregates. With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. It is also the world’s most widely used material for construction – from bridges to large buildings, concrete forms the very foundation of our infrastructure.
