The answer to this question depends on who you ask.
While there is no hard and fast answer to it, concrete is widely used as a building material, a material that is durable, can withstand extreme heat and extreme cold, and can be recycled to make new construction materials.
As it stands, concrete tiles are not used for the construction of buildings in Australia.
The only concrete in Australia, which has a concrete foundation, is the concrete used in residential buildings.
The Australian Bureau of Statistics says that in the year ending March 2019, there were just 726,000 residential dwellings with concrete floors, down slightly from the 722,000 in the same period a year earlier.
However, with the number of people moving into the country, demand for concrete will increase in the future.
And while that demand is expected to increase in line with the growth in population, it could also lead to shortages of the material.
“It’s hard to predict when we might have concrete floors in our homes, but the reality is that if there’s a shortage of concrete in the market, it will be around 2020,” says Dr Stephen Jones, a lecturer in urban design at the University of Melbourne.
While the supply of concrete is in a steady decline, the demand for it is growing.
In 2016, the number in use in Australia was 8.3 million, down from 9.4 million in 2015.
In the year to March 2019 the demand was 12.1 million tonnes, down by 4.5 per cent on the year before.
But demand is rising, and this demand could become unsustainable in the short term.
Dr Jones says the supply is going to be dependent on demand and demand will only increase if demand is driven by the demand of the residential market.
“In the longer term, we’re going to see more people using concrete floors because the supply will be limited,” he says.
“We’ll probably see the demand go up again in 2020.”
He predicts that in 2020, about 70 per cent of residential dwellings in Australia will have concrete, and he predicts that by the end of the decade, that number will be closer to 85 per cent.
However in the long term, there are more things to consider when it comes to concrete.
“When you have a lack of supply, it’s going to lead to some issues with health and safety and safety for pedestrians and other pedestrians,” he explains.
“But the reality here is that we’re already seeing a huge increase in pedestrian fatalities in this country.”
In Sydney, a major road safety initiative is looking to encourage more people to use the concrete floor of their homes, and the city has also recently launched a scheme to encourage construction of new residential developments that use concrete.
But while the demand is high, the supply, if there is one, is limited.
The State Government has set aside $200 million in a pilot scheme to help municipalities and communities get more concrete.
Dr Evans says that the demand will depend on what kind of housing developments they want to build.
“There’s going on an enormous amount of new housing development in Sydney that’s going forward that’s using the same material, so it’s hard for us to predict how many new homes there are going to come in the next couple of years,” he adds.
He says the State Government will be working with developers to see what works best for them, but that there will be a need for more regulation to ensure that new developments can be constructed on concrete. “
However, if they’re being built on a concrete slab, the costs are going up because they’ll be building them on a slab that’s already been used for construction, and it’s just not sustainable.”
He says the State Government will be working with developers to see what works best for them, but that there will be a need for more regulation to ensure that new developments can be constructed on concrete.
However he says that if the State government is going the right way, there will still be demand for the material in the residential sector.
“If the State is really thinking about the needs of the population and the needs for affordable housing, and if it’s willing to work with local governments and developers to find some solutions to some of these issues, then I think that there’s going a very good chance that demand will increase,” he concludes.
