About Production & Supply (Building Materials)

Concrete blocks:

Concrete blocks are precast composite masonry units made of cement, sand and water and are moulded in various sizes. According to the British Standard (BS 6073:1981 Part-01) a block is a heterogeneous building materials with a unit that is larger in all dimensions that what is required for bricks. But no dimension should be larger than 650 mm or the height should be six times the thickness or greater than the length when set in their normal aspect,

It should be noted that in (BS,: 6073:1981) The distinction between blocks and bricks has been removed and replaced by “ Masonry Unit”

It has been reported by some researchers that concrete blocks are the major masonry units used in dfferent countries in the world accounting more than 90 % of the country’s physical infrastructure. Concrete blocks are reasonably priced when compared to other building materials.

Interlocking Paving Block

Hollow Blocks are ideal for industrial and commercial application. Strong reinforced walls can be constructed quickly and with ease. The concrete compacted by high pressure and vibration gives substantial strength to the block. Our advanced and highly technological measures applied into proper curing further increases the compressive strength of the blocks. The blocks have the features of rapid Execution of work, increase in floor area, reduce construction cost, better insulation properties, significantly higher durability, good bonding of mortar & plaster. Applications for: Building Construction, Guide wall etc. Weight: 10.5 & 13 Kg

Rate: 45 Tk. To 60 Tk.

Size: 390 mm X 190 mm X 100 mm

Advantages of hollow block :

The hollow block will give a different look as it reduces the energy bill to create an environmentally friendly environment in the building.
Solid hollow blocks require less maintenance and provide insulation from sound, heat, and fire-resistant.
The joints in these blocks require less cement mortar, little or no plastering thus speeding up the construction process.
High dimensional accuracy and consistent finish make it an ideal building material for building load-bearing structures and building partition walls.
These hollow concrete blocks have high-stress bearing capacity hence widely used in building construction practices.
Concrete hollow blocks are lightweight hence used in the construction of homes in earthquake-prone areas.
These blocks are more cost-effective than other traditional wall systems or wall construction systems.
It is high quality, high strength, uniform size, and shape.
It is completely energy-efficient does not require any non-renewable resources for its production.
Also, it does not disturb the ecosystem so they are either environmentally friendly or eco-friendly since the waste and local resources can be used for its manufacture or production.
It can also be manufactured at the site.
Hollow space in blocks makes masonry work soundproof, heatproof and damp proofing.

Double Interlocking bricks is completely made by vibration table similar properties of machine-made bricks. This bricks also have high load bearing capacity, enhanced weather resistance properties, low maintenance and economical.

Rate: 13 Tk. To 15 Tk.

Applications: Partition wall, Boundary wall, Beautification work
Seize: 240 mm X 100 mm X 70 mm

Well-furnished brick is completely made by vibration table similar properties of machine-made bricks. This bricks also have high load bearing capacity, enhanced weather resistance properties, low maintenance and economical.

Rate: 13 Tk. To 15 Tk.

Applications: Partition wall, Boundary wall, Beautification work,Walk way in the park, Footpath

Auto Bricks are ideal for industrial and commercial application. Strong reinforced walls can be. The concrete compacted by high pressure and vibration gives substantial strength to the brick. Our advanced and highly technological measures applied into proper curing further increases the compressive strength of the bricks. This type of bricks reduces construction cost, significantly higher durability, good bonding of mortar & plaster.

Applications: Building Construction, Boundary wall, Guide wall etc.

There are two type of universal paving block available. One is completely machine made & other one is completely vibration table with different color, universal paving blocks with high load bearing capacity, enhanced weather resistance properties, low maintenance and economical. Universal Paving block are manufactured from coarse aggregates.

Rate: 20 Tk. To 40Tk.

Applications: Internal Roads, Road Intersections, Bus Stand and Bus Stoppage, walk way in the park, Footpath, Car Parking, Heavy duty paving area, Beautification work.

Size: 220 mm X 110 mm X 100 mm, 220 mm X 110 mm X 80 mm, 220 mm X 110 mm X 80 mm

Low maintenance and economical.

Applications: Internal Roads, Walk way in the park, Footpath, Car Parking, Beautification work.

Interlocking Paving block contains three-dimensional machine-made interlocking system and contain similar properties of other paving blocks. Due to its Inter- Locking Mechanism, it creates a chain of link that further enhances the strength and the bondage amongst the blocks. This block also completely machine made, high load bearing capacity, enhanced weather resistance properties, low maintenance and economical.

Applications: Internal Roads, Road Intersections, Bus Stand and Bus Stoppage, Walk way in the park, Footpath, Car Parking, Heavy duty paving area, Beautification work.

NAS Concrete Industries are ensuring the following steps for quality control production:

Water, sand and aggregates must be clean and devoid of organic contaminants.
The sand are using for block production keep always in dry condition
Cement and aggregate must be mixed until the color is uniform
Only add enough water to the mixture to make it workable
Digital balance and wheelbarrows are using for controlling the ratio.
All mixtures never be retempered by adding more water because doing so wekens the final product and used up within two hours of initial mixixing
Ensuring the complete compaction
Blocks are curing carefully after Production. Curing is the process of keeping the blocks at an ideal temperature and moisture level to promote the hydration of the cement and the development of maximum strength. The curing period for blocks maintain at least 14 days.
