Fly ash is a siliceous or siliceous and
aluminous material that, by itself,
possesses little or no cementitious value.
In the presence of water, however, fly ash
chemically reacts with calcium hydroxide
released by hydration of Portland
cement to form compounds possessing
cementitious properties. This can result
in a denser, durable concrete.
Fly ash also can be used to improve concrete workability,
decrease permeability, reduce sulfate attack, decrease
bleeding and segregation, reduce shrinkage, reduce heat
of hydration, increase compressive strength and increase
flexural strength. Fly ash is suitable for a variety of concrete
construction applications from general construction to
dams, piers, massive mat placements, footings and similar
structures.
Silica sand is used in the manufacturing of glass, mortar, paint, and rubber, and as a filler in various products. Quartz sand is used in the manufacture of abrasives, cement, and glass.
Quartz is one of the most well-known minerals on the earth with numerous uses. Sand, which is composed of tiny Quartz pebbles, is the primary ingredient for the manufacture of glass.
We are Quartz exporters from Northern Pakistan, land that is rich with quartz minerals.
We welcome orders from the Middle East, East Asia, and several other countries and ensure timely shipment.
The price mentioned is USD $114/tonne when shipping to North America.

Pillow pak is a desiccant packet that is actually an absorbent used in various places. The desiccants used in the pillow packets are free from DMF and are also non-toxic in nature. The largest range of desiccant packs in tyvek(FDA approved)and laminated film (clear view ) substrate available in sizes from .25 g, .50 g, 1 g, 2 g, 3 g, 5 g, 7 g and 10 g in four different desiccants: Silica Gel, Clay, Molecular Sieves and Clay and Blends of these as well, called the 50-50 packs for moisture and odor control.
LGS1500 is a synthetic graphite heat sink.LGS1500 has an unique grain orientation, lamellar structure can be well adapted to any surface, even heat conduction along the two directions. Plane thermal conductivity of up to 1900W/m-K. LGS1500 products while also the thickness of uniform heat to provide thermal isolation. Heat shielding and components while improving the performance of consumer electronics products. LGS1500 composite graphite sheet is a polyimide sintered novel film material with high thermal conductivity and excellent product design flexibility.
Features & Benefits:
1.High thermal conductivity -flat heat conductivity can be up to1900W /m-K,40% lower thermal resistance than aluminum, 20% lower than copper
2.Ultra-light -than the same size aluminum to 30%lighter, 80%lighter than copper
3.Thin -thickness from 0.017 �?0.025mm and 0.04mm
4.Temperature resistance-using temperature up to 400, the minimum can be lower than-40
5.Easy processing-can be made into different die sizes, shapes and thickness, can provide planar sheet die
6.Ease of use-graphite heat sink can be applied to any smooth flat and curved surfaces
7.Flexibility- easily with the metal, the insulating layer or double-sided adhesive made of plywood, increase design flexibility in the back with adhesive
LGS300 graphite thermal pad is a new thermal interface material. It transfers heat along the two directions, shielding heat source and components meanwhile improving the performance of consumer electronics products. The thermal impedance of LGS is very small and can completely replace the high-performance thermal grease while avoiding the shortcoming of poor and dirty thermal grease process. LGS thermal conductivity is three-dimensional, that is not only it can transfer heat between the heat source and the radiator in the vertical direction, but also in the vertical direction, which ensures that it can quickly transfer heat out in vertical direction when the partial heat is high. Therefore, LGS thermal film is very suitable in the small space to efficiently transfer heat generated by heat source.
Features & Benefits:
Ultra-high thermal conductivity, easy to operate;
Low thermal resistance
Light weight
Typical Applications:
IC ; CPU; MOS; LED; Heat sink; LCD-TV; Laptop; Communication equipment; Wireless switch; DVD; Hand-held device; Camera/digital camera; Mobile phone
