Plastic bubbles in constructing
In recent years, great attention has been paid to research into new techniques and materials in the construction industry, in order to reduce costs, save time but keep the quality of construction.
One of the latest innovations are plastic balls or bubbles that are placed between two layers of concrete. Various types, shapes, textures of plastic surfaces, design of concrete mix and setting conditions can modify concrete properties when plastic is used as a substitute for sand. Reduced demand for sand in the construction industry can benefit the environment. Replacing sand with plastic balls results in the concrete being almost as strong as conventional concrete mix and large quantities exceeding several hundred thousand tons per year, and reducing plastic waste. This not only reduces the amount of concrete, which is one of the main emitters of carbon dioxide into the atmosphere, which accounts for 8% of world emissions, but also reduces the energy use required for transport.
After many researches on how to reduce the use of concrete and sand, the best results were given by the use of these bubbles or balls – a non-traditional system of concrete blocks. They are lined up at equal intervals to reduce the amount of concrete in the block. Thanks to the gaps in the balls, the use of concrete is reduced by about 30% compared to a classically poured block. With reduced use of concrete, this becomes a green product.
This construction technique involves placing balls between the upper and lower zones of the reinforcement in the zone of the block that is not the supporting structure, after which the concrete is poured. It is applied in those parts where concrete is not necessary for static reasons.
By using plastic balls or bubbles, the environment also benefits. The balls are made of 100% recycled plastic and allow the reduction of CO2 emissions into the atmosphere by less use of concrete. The weight of the building is decreasing. Optimal technique and economic realization of the project are achieved.
