NCT A Malaysian Technology.
We all know that concrete is heavy and the No.1 ingredient usage for construction anywhere in the world today, but not many people knows that concrete's density and compressive strength can be control. Cement is concretes main bonding agent and others are just fillers like sand and aggregates. In NCT, it is exactly the same only we use air as another filler, we can control it's density by amount of tiny air pockets we add into the mix via foaming process.
We have developed a technology where we use a stable foaming agent and a foaming generator to create NCT. Not only can we control concrete's density precisely, we can control it's strength as well. Normal Concrete has a density of 2400 kg /m3, NCT's density range from 1800,1700, 1600 down to 300. This 16 type of densities have over a 100 type of mixes and can be applied onto so many applications that will change the way cement is use currently worldwide.
For the last 13 years, R and D has been done on multiple apply able possibilities ranging from low densities mix for heat insulation, thermal acoustic applications, void infilling, roof-deck insulations applications, bridge approach for undulating preventions, bridge decks, soft ground base for roads, for housing raft foundations and many more on infrastructure applications. Clay Bricks and cement bricks are successfully being replace by NCT proving its thermal and acoustic value, prefabricated load bearing panels, blocks and many other pre cast ad cast in-situ has been successfully applied.
NCT most successful methods to date is its house casting, you can cast a lightweight block or a lightweight panel but we recommend you cast a house instead as it is the same process but..., in pre-casting you need the ingredient, you need mold, you need manpower and most of all you need logistic and then skill labor to built it at site, NCT house casting is different, you set up Stay in Place Formwork ( NCT-SiPF) or Reusable Formwork (NCT-RF) at site and you cast, you PaintCoat (NCT-PC) that's it. In whatever methods currently being use nothing can be compare to NCT house casting, not only is it economical, it is fast to built and heat resistant, soundproof and most of will not collapse, it may crack in case of earthquake.
An innovative new technology is being developed for residential, industrial and commercial building applications. With strength to density ratios approximately double existing products in the market, the new innovative lightweight wall technology can potentially be used in both non-load bearing as well as load-bearing applications.
- bulk densities approximately half that of conventional concrete / 1200 kg +/- 50 % ( 600 kg/m3 to 1800kg/m3)
- compressive strengths up to 30 MPa ( up to 4 times stronger then traditional autoclaved aerated concrete )
- excellent thermal and sound insulation properties
- non-combustible, good fire rating
- cost saving through fast speed of construction and ease of handling
Collaborative Research
The environment friendly technology, which also makes productive use of waste into an alternative building material called NCT. The technology is easily executed at the project site itself. NCT is even simpler to produce than ordinary concrete, for it compacts by itself and does not warrant vibration or compaction.
This new technology is the result of a recently completed commercial R&D program with UiTM, KUiTTHO, UTM and a few other agencies. This 2 year R&D program redeveloped the technology to a pre-pilot stage and included development of practical advanced manufacturing procedures and extensive materials and structural testing of the new product. The R&D program was supported by the Malaysian Government through an R&D START grant from the IRPA R&D Industry. All you need to obtain foam concrete are a foam generator and a foaming agent, as foamed concrete is simply a mixture of a cement mortar slurry with foam, which can be prepared in an ordinary concrete mixer, or even without it, if only a small quantity of the material is necessary.
Foam concrete is a mixture of cement, fine sand, water and a special foam, which once harden results in a strong, lightweight concrete containing millions of evenly distributed, consistently sized air bubbles or cells.
The density of foam concrete is determined by the amount of foam added to the basic cement, sand and water mixture. Foam concrete is both fire- and water-resistant. It possesses high (impact and air-borne) sound and thermal insulation properties.
Foam concrete is similar to conventional concrete as it uses the same ingredients. However, foam concrete differs from conventional concrete in that the use of aggregates in the former is eliminated. Foam aeration or bubbling agent is used to absorb humidity for as long as the product is exposed to the atmosphere, allowing the hydration process of the cement to continue for its ever-continuing strength development.

NCT AL NASHI ALEX SDN BHD ( 668250 - A )
A MALAYSIAN TECHNOLOGY.
An innovative new technology has been developed for the construction of residential housing. The very versatile controllable lightweight concrete has excellent thermal and sound insulation properties, it is non-combustible, has good fire rating. It can be produced easily and can be used for casting into any shapes and can be pumped straight to where it is required.
Combining a series innovative and visionary method, we have come out with a systemize way of casting lightweight concrete houses which are stronger, better and most of all very much more economical then whatever current methods. Even projects infrastructures will gain tremendously from this system as roads, conceal perimeter drainage and storm water drainage can be cast in-situ as well with the system. By just using lighter weight walls for high-rise buildings, up to 25 % saving are achieve just on the pilings and structures not to mention its expected economical side of NCT wall castings.
NCT:
NCT-CORE FORMWORK SYSTEM (NCT-CFS)
This lightweight panel are strong, reuseable many times are easy to erect and dismantle. And most of all it is cheap. This systematic method helps speed up the productions of better walls. |
