Concrete is the main building material in the world, and reducing its cost can significantly reduce costs in the construction of houses. One of the most important and expensive components of concrete is the sand that must be mined, cleaned of impurities and sort — why haven’t scientists find a replacement? According to researchers from Australia’s Deakin University, the alternative can be small particles of glass which is unsuitable for recycling.
The researchers believe that created on the basis of glass the concrete is able to provide not only the structural integrity of their cheapness, but also can clean the planet from rubbish. Although glass and is considered a relatively environmentally friendly material, its tiny particles can be sent for reprocessing due to the complexity of sorting. At the moment, mankind has huge stocks of old glass, which can be used in the construction industry.
Solid and cheap concrete
University staff propose to use glass in polymer concrete is a relatively new material in which no deficiencies of cement concrete. Its pores are not filled with the standard binders like cement and silicate, and polymers. Thanks to them, the concrete can easily withstand moisture, extremes of temperature and even exposure to chemicals. The crushed glass, which it is proposed to use instead of sand, can enhance these properties.
The creators of new material to assure that it is perfectly passed the tests of strength. While it remains unclear at what level is the strength of the material. Currently one of the most reliable types of concrete is brand M1000 — it is widely used in the construction of such important objects as dams, mines and heliports.
Anyway, if the concrete is glass-based at least a little better than conventional concrete and thus less expensive construction companies should be sure to look at him. The development of new types of building material are engaged in other countries — for example, Singapore has created a concrete that is extremely hard to break.
