QuantCrete nanoadditives are presented as an efficient & essential remedy for preventative road & infrastructure maintenance, in order to help curtail the high cost of road extensive repairs or future replacements, which can range from hundreds of millions to billions dollars per annum.
Asphalt or bitumen is used in road construction . It's a petroleum product which adds volatility to its pricing. Although its content in road construction is ~ 4 - 5 % , it is the most expensive component, averaging ~ $115,000 per kilometre ($184,000 per mile). It is also a significant environmental air pollutant and a carcinogen.
Asphalt concrete (AC) which is used to build roads, refers to concrete as a composite material composed of mineral aggregate adhered with asphalt/bitumen as a binder, which is the (heated) liquid portion of the mix.
Asphalt however, is less durable than concrete. We propose the use of QuantCrete to enhance the durability of concrete in aspects such as increased flexural strength to prevent cracking, resistance to heat- and frost-cycles and salt corrosion. With an increased durability, less asphalt is used.
QuantCrete also offers the ability to use between 15 - 40% less cement per cubic meter/yard of concrete without compromising its performance. This further drops the costs of road construction as well as its carbon footprint. The improved workability of concrete with QuantCrete also facilitates the surface modoification of roads during construction, for smoothner finishes and reduced noise.
Our QuantCrete nanoadditives offer pathways to circumvent and/or minimise the use of toxic construction materials by providing a means to render durability to more sustainable & less toxic systems. In concrete, QuantCrete nanoadditives enable :
lower porosity
High corrosion resistance
Low alkali reactivity
Mitigate sulphate Attack
Increase soil Stabilisation
Shield nuclear & electromagnetic radiation
Increase compressive & flexural strength
Improve waterproofing
As such, QuantCrete products resolve a vast range of issues that cause failure in concrete which will confer better durability, reduce maintenance frequency rates and lower road construction costs. Some of the issues that cause failure in AC and the QuantCrete products used to mitigate them entail :
- Heat & strong sunlight which causes asphalt to oxidise, stiffen and become brittle | QUANTCRETE FLEX
- Cracks caused by water trapped under the road freezing & expanding | QUANTCRETE FILLER , QUANTCRETE CURE & QUANTCRETE FLEX
- Potholes resulting from low support, water saturated sublayer silty or clay soil, sublayer soft soil stabilisation and sulphate attack mitigation | QUANTCRETE EARTH & QUANTCRETE CURE
- Low flexural strength that causes depressions in airport runways and highways due to material fatigue especially from heavier aeroplanes and slow moving (heavy duty) vehicles | QUANTCRETE FLEX
ENVIRONMENTAL BENEFITS
From an environmental perspective, QuantCrete can serve as a bitumen partial substitute so as to :
Help increase the resilience, longevity and durability of airport runways, bridges, roads and highways
Lower the concentration of bitumen used in road construction in order to improve air quality & as such
Reduce the negative environmental impact of bitumen/asphalt via the development of lighter-coloured roads that absorb less solar radiation thus minimising their contribution to the urban island heat effect.
Lower the carbon footprint of road construction by enabling the development of more robust concrete with less cement.
Shorten construction time, by providing rapid strength gain

QUANTCRETE RADIATION SHIELDING SYSTEMS
QUANTCRETE RADIATION SHIELDING SYSTEMS
Radiation shielding simply means having some material between the source of radiation and you (or some device) that will absorb the radiation. Radiation shielding is very crucial for the protection of people. Particularly, for the protection of personnel in nuclear power plants, medical centres and the environment, from the harmful effects of ionizing radiation.
In nuclear power plants, the central problem is to shield against gamma rays and neutrons. Of the various forms of radiation known to man, neutrons are considered to be the most severe and dangerous radiation to the body. This is due to their high kinetic energy and because they are uncharged, neutrons are more penetrating than alpha radiation or beta radiation. In some cases, they are even more penetrating than gamma radiation.
In nuclear power plants, fast neutrons create structural defects, which result in the embrittlement of material of pressure vessel in nuclear power plants. The neutron absorption reaction is hence the most important type of reaction that take place in a nuclear reactor.
BENEFITS OF NANOTECHNOLOGY
BENEFITS OF NANOTECHNOLOGY
Scientific studies unanimously show, that radiation shielding with nanoparticles is much more effective than with micro-particles. As the nanoparticle size decreases, the radiation shielding capacity increases. When such nanoparticles are infused in a grout prior to coating on a surface, only a thin layer is sufficient to shield thermal neutrons.
Pores in cement/concrete without nanoparticles create decrease the mechanical strength, density, as well as the ability of cement/concrete to attenuate radiation. When the pores in cement/concrete are filled with ultrafine nanoparticles with sizes smaller than harmless pores ( < 20 nm) the mechanical strength, density and radiation attenuation capacity of the cement/concrete system increases substantially. With the cement/concrete mixture performance maximized by virtue of such radiation-attenuating nanoparticles (< 20 nm), it performs achieves enhanced radiation shielding goal simultaneously with a higher heat and embrittlement resistance.

UNDERSTANDING RADON:
Radon (Rn) is a radioactive, odourless, colourless, tasteless noble gas. Rn is a contaminant, that affects indoor air quality, worldwide. According to EPA policy-oriented estimates, Rn is the number one cause of lung cancer, among non-smokers.
Rn enters a building most often directly through the soil at the lowest level of the construct that is in contact with the ground. This typical occurs through cracks in solid foundations and walls, construction joints, gaps in suspended floors, cavities within walls and around service pipes.
DIMENSION-BASED SOLUTION
Radioactive radon particles vary in size.
When attached to an aerosol, radon particles range in size from 50-300 nm (0.05 - 0.3 μm)
Unattached radon particles range from 3 - 5 nm (0.003 - 0.005 μm) in size
HOW TO USE QUANTCRETE IN RADON MITIGATION/MINIMISATION EFFORTS
To minimise the penetration of Rn into buildings, QuantCrete is hence offered to substantially lower porosity, air permeability and mitigate of crack formation in concrete and mortar. QuantCrete nanoparticles are of the same size range as unattached radon particles.
As such QuantCrete nanoparticles used to densify concrete and can form a dense structure therein, acting as a physical as well as chemical barrier, to prevent the diffusion of Radon, through a basement concrete floor.
To achieve this, the QuantCrete nanopowder can be used as an integral ingredient in the manufacture of precast slabs and foundation concrete or, mixed with a liquid cement and injected within particularly hard to visualise and detect sub-micron and nanoscopic pores, cracks & cavities that cement particles can not reach or penetrate, in order to create a denser seal, that minimises the likelihood of Rn gas infiltrating the building, via its ground level and sub-terrain/basement walls.
This nanotechnology-based approach offers a durable, sustainable, long term mitigation effort, to prevent Rn gas from entering the building through the underlying soil.
