Russia: Moscow authorities considering construction of roads from concrete

The Moscow authorities are considering the use of concrete for road construction. It is claimed that concrete is supposed to be more durable than asphalt; heats up less and does not crack and slip if it contains polymer additives (polymer concrete). However, it is also claimed that concrete pavement can produce more noise and their construction costs more.

Self-healing cement claimed to stop cracks during drilling

US researchers say they have developed a type of 'self-healing' cement that would enable an 87% reduction in cracks during drilling applications.

The government-run Pacific Northwest National Laboratory (PNNL) claims that its self-healing cement can outperform conventional concrete, offering a potentially pollution-preventing technology for the growing geothermal industry.

The new cement variant uses a flexible polymer ingredient to repair fractured surfaces and fill cracks, which the Richland, Washin
