| 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 and clay.The silt and the clay presence in the sand reduce the strength of the concrete and holds dampness.The natural river sand is the product of sedimentation. mica, coal, fossils and other organic impurities are present in the river sand above certain percentage which make the sand useless for concrete work. | ||
| Acute shortage and high price for river sand has lead to the adulteration of sand with salty sea sand which has raised serious concern among builders. High StrengthThe superior shape, proper gradation of fines, smooth surface texture and consistency in production parameter of chemically stable sands provide greater durability and higher strength to concrete by overcoming the deficiencies like segregation, bleeding, honey combing, voids and capillary. Greater workabilityThe crusher dust is flaky and angular in shape which is troublesome in working. There is no plasticity in the mortar which makes yet difficult for the mason to work. Where as the cubical shape with grounded edge and superior gradation gives good plasticity to mortar providing excellent workability. | ||
| Sand is the general term for broken down granules of minerals or rocks, technically between about one-sixteenth of a millimeter to two millimeters in diameter, falling between silt and gravel in the spectrum of sizes. There are many varieties of sand in the world, each with their own unique composition and qualities. This sand is obtained from banks or beds of rivers. River sand is fine and consists of fine rounded grains. | ||
| The color of river sand is almost white and Grayish. River sand is usually available in clean condition and is used for plastering. | ||
| A hard rock, bluish in color, which is crushed and used for construction purposes. The byproduct Blue Metal may replace sand and will be an artificial sand and will be used in construction of buildings. We offer a wide range of blue metal chips that are acquired from our own quarry. | ||||

STANDARDS FOR AGGREGATESAggregates and test methods. These new Standards will change the way in which we look at our aggregates, although the materials will be the same there is a new way of defining aggregate sizes, different sieve sizes with new grading and a new set of tests for physical and mechanical properties. | ||||

GRADING CATEGORY (Gc)
There is now a Grading Category (Gc) which specifies the percentage of material passing d/D, therefore a 10/20 would have a grading category Gc85/20 this means that up to 85% of the material can pass the 20mm sieve (D) and up to 20% can pass the 10mm sieve (d).
The grading for a 10/20 Gc85/20 would be

FLAKINESS (FI)The Flakiness test has changed you now use a bar sieve along with the new sieve sizes, the results are lower then the old method and for Asphalts a Flakiness of less then 35 is now acceptable FI35.
Blocks are indispensable for modern building and construction industry. These blocks are manufacturing from mixture of cement, sand and stone chips. During the process the raw material is mixed from cement, fine aggregates and a natural expansion agent. They are most durable and a good insulator. These bricks have high compressive strength and available in different sizes which are used in construction industry. These blocks find wide applicability and construction cost is largely reduced.

| Hollowblocks can be used like any other masonry unit to build foundations, walls, arches and corbels, etc. A typical hollow block is equivalent to 4.5 bricks, thus construction is faster than with other masonry units. The mortar used is also, less which results in cost saving. | ||
| Our entire range of hallow bricks are made of latest concrete compact technology with higher compressive strength & low water absorption. We ensure that the formulation of our hollow bricks is done using quality raw material that ensures its good performance. Why hollow blocks? It reduces to 60% in cement mortar consumption. It is cheap having its high value. It reduces cost of construction. Natural thermal insulation. Superior compression strength. Light weight (up to 40% reduction in dead load). Environment friendly. Additionally, Hollow Blocks are lightweight (up to 40% reduction in dead load) & provides natural thermal insulation. 30% reduction in plastering cost. | ||
| ROAD WORKS MATERIAL | ||
| Road constructionrequires the creation of a continuous right-of-way, overcoming geographic obstacles. Various Types of SandThere are two types of sand.1. Pit Sand2. River Sand | ||
| Pit Sand (Coarse Sand) Also, called as Coarse Sand. Pit sand is obtained by forming pits into soil from Quarries. It consists of sharp angular grains which are free from salts. It is coarse sand which is usually used in concreting and has reddish yellow color normally.Sand usually composed of grains that are relatively angular; it often contains clay and organic matter. When washed and screened it is good sand for general purposes. Due to the recent shortage of river sand resulting from a rapid growth of concrete constructions, sea sand and pit sand are increasingly used everywhere. Why do we go for Pit sand?
River Sand This sand is obtained from banks or beds of rivers. River sand is fine and consists of fine rounded grains. The color of river sand is almost white and Grayish. River sand is usually available in clean condition and is used for plastering. GravelGravel is an important commercial product. Gravel is composed of unconsolidated rock fragments that have a general particle size range and include size classes from granule- to boulder-sized fragments. Many roadways are surfaced with gravel, especially in rural areas where there is little traffic. Where natural gravel deposits are insufficient for human purposes, gravel is often produced by quarrying and crushing hard-wearing rocks, such as sandstone, limestone, or basalt. Quarries where gravel is extracted are known as gravel pits. Multiple types of gravel have been recognized, including: Bank gravel:gravel intermixed with sand or clay. Bench gravel:a bed of gravel located on the side of a valley above the present stream bottom, indicating the former location of the stream bed when it was at a higher level. Fine gravel:gravel consisting of particles with a diameter of 2 to 4 mm. Lag gravel:a surface accumulation of coarse gravel produced by the removal of finer particles. Pay gravel:also known as "pay dirt"; a nickname for gravel with a high concentration of gold and other precious metals. The metals are recovered through gold panning. Pea gravel:gravel that consists of small, rounded stones used in concrete surfaces. Also used for walkways, driveways and as a substrate in home aquariums. River run gravel:naturally deposited gravel found in and next to rivers and streams. And, a lot more.Gravels are embedded in the middle of each cemented sand layer. The size and number of embedded gravels varies. After two days curing, a series of unconfined compression tests is performed on the cemented sand with dispersed gravels. In addition to that, a series of direct shear tests is also carried out on clean sand with gravels to evaluate its friction angle. Gravel CrusherGravel crusher is a type of stone crushers that is used to crush gravel. Gravel is the raw materials for construction, road, bridge and railway building and small gravel are also important for the manufacture of concrete. LimestoneLimestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate.Limestone was also a very popular building blocks, since it is hard, durable, and commonly occurs in easily accessible surface exposures. Limestone is readily available and relatively easy to cut into blocks or more elaborate carving. It is also long-lasting and stands up well to exposure. | ||
