From technical point of view the rich mixes may lead to high shrinkage and cracking in the structural concrete, and to evolution of high heat of hydration in mass concrete which may cause cracking. In this study, we have used grit and crushed sand for the design mix and found the characteristic compressive strength…
3. Concrete Sand. Concrete sand consists of granite rock, gneiss, or limestone. This sand has angular granules and works best when mixed with cement. Besides usage in concrete, concrete sand can also be used in bedding pipes. This type of sand is usually crushed in a quarry and filtered severally to remove huge fragments and large rocks.
Crushed Sand (-3mm – 6.7mm) Crushed Sand is a very specialised product – we pride ourselves in being one of the few suppliers with premium quality Crushed Sand. Uses for Crushed Sand include r oad construction, mixing with asphalt, construction fill, and in the production of construction materials like concrete blocks, bricks, and pipes.
Suppose, proportion of concrete is taken as 1:2:4. (one part cement : two part sand : four part aggregates). Volume of concrete work is taken as 500 cft. Now, in order to determine the quantity of cement in cft., put the cursor on the specific cell of concrete volume and apply the formula i.e. = (D2*1.54*A2)/ (A2+B2+C2).
The cement paste wraps the stones and sand and fills the pores between the aggregates to bond the skeleton composed of the stones and sand into a whole. To make high-quality concrete, sand must meet certain quality requirements: the thicker the sand, the larger the volume, and the smaller the amount of cement slurry consumed.
Manufactured sand (M-Sand) is a substitute of river sand for concrete construction . Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material. The size of manufactured sand (M-Sand) is less than 4.75mm.

The key to success will be the ...
Concrete is rated on a system that indicates the strength of the mix after it's cured for approximately a month. To make the concrete stronger, add more cement or less sand. The closer you bring the ratio to an even one-to-one of sand to cement, the stronger the rating becomes. This principles works in the opposite direction as well.
To make concrete though which will greatly extend the volume produced you mix in gravel or sand or crushed brick. Proportions are an endless subject of debate but the formula of 1 part cement, 2 parts sand and 3 parts gravel by volume is a good starting point. Mix the dry ingredients first and then slowly add water. You want "workable" concrete.
