Self-healing concrete is being trialled by a group of researchers from Bath, Cambridge and Cardiff universities in the UK.

The Materials for Life project is investigating three self-healing technologies that could eventually be individually or collectively incorporated into concrete as it is made.

It is claimed that self-healing concrete could significantly reduce the annual bill for repairing concrete buildings and structures.

The trial is investigating three technologies: shape-memory polymers,

The Kolo milliona-based (the Moscow region) LafargeHolcim plant has begun production of the new cement base for mortars under the Kelma brand.

It is said to be characterised by high strength, fine adhesion to surfaces, and a long retention of mobility that provides for the mortar's plasticity necessary for construction works without adding extra water.

The product is being sold in 50kg bags.

Algerian construction material imports have receded by 27.4% in value to US$1.9 billion (€1.77 billion) and by 4.8% in volume to 8.39 million tonnes in the first three-quarters of 2015 compared to the same 2014 period, thus suggesting that the decrease is more due to a fall in prices rather than a genuine drop in imports.

Cement imports have fallen by 21.41% in value to $352.32 million, while they have only dipped by 2.11% in volume to 4.8 million tonnes.

Similarly, iron and steel imports have shrunk

According to Oficemen figures, cement consumption in Spain fell 2.4% to 1,025,120 tonnes during October 2015.

Consumption in the first ten months of the year rose 4.3% to 9,564,783 tonnes.

The Baselcement holding company's plants produced about 1.9 million tonnes of cement and clinker in January-September 2015, 12% down, compared with the similar period of 2014.

Almost 1.2 million tonnes of cement (+26%) was produced at Serebryansky Cement Plant in nine months.

Achinsk Cement doubled its high-grade cement supplies (PC 500-D0 and CEM I 42.5B) to 120,000tonnes. The plant increased the commercial clinker supplies 3.5-fold.

The Turkey-based consortium Dal Engineering Group and the Almalyk Mining and Metallurgical Company (MMC) has signed an agreement on construction of a cement plant in the Surxondaryo region.

According to preliminary information, its capacity will total up to 1.5 million tonnes of Portland cement/year.

The investments are estimated at some US$225 million (€208.94 million). Of that amount, about $90 million will be provided by the Uzbekistan Fund of Reconstruction and Development and US$24.4 million by t

The Ukraine-based companies Malo-Kokhnovsky Karier and Bekhovsky Granitny Karier have been licensed for crushed stone imports in Russia and have resumed their deliveries.

A total of 12,700tonnes was supplied as of mid-November. The Belgorod region (the Central FD) accounted for 93.4% and Moscow for 6.6% of the supplies.

The Crimean government has recommended geologists to activate the crushed stone prospecting works on the territory of the republic.

According to head of the republican Ministry of Ecology Gennady Narayev, crushed stone that is now being mined is unsuitable for use in the full cycle of road construction.
