Sponsors and partners are the Housing Financing Fund and the Icelandic Road Administration.

Development of microscopic crystals on the surface of cement

Project manager: Kristjan F. Alexandersson.

This involves research on the development of microscopic crystals on the surface of cement grains as the cement hardens. Sponsors and partners are the Icelandic Research Fund and W.R. Grace (USA).

Stability and viscosity manipulation of concrete

Project manager: Olafur H. Wallevik.

The main aim of this project is to design a new device, Segrometer-4SCC, which builds in part on the experience of Rheometer-4SCC and can measure the stability of the concrete in terms of separation. Sponsors and partners are the Rannís Technical Development Fund, Steyputækni ehf (ConTec), Golden Bay Cement (New Zealand), Norcem (Norway), the Housing Financing Fund and Landsvirkjun.

Use of carbon fibres in cement-based materials

Project manager: Sunna O. Wallevik.

Research is performed on the use of carbon fibres in cement-based materials and comparative measurements are taken on other fibre-reinforced concrete.  The sponsor and partner is the Housing Financing Fund.

Effect of plastic supporting fibres on the rheology of SCC concrete

Project manager: Olafur H. Wallevik.

The effect of different amounts of polymers fibres in self-compacting concrete on the rheology of concrete is examined. The sponsor and partner is the Housing Financing Fund.

Icelandic basalt fibres for earthquake-resistant concrete

Project manager: Olafur H. Wallevik.

This involves the use of basalt fibres and products made out of basalt fibres for reinforcing concrete and repairing old concrete.Sponsors and partners are the Rannís Technical Development Fund, the Icelandic Road Administration, the Hi-Tech Center of Iceland, the Housing Financing Fund and Reykjavík University.

Rheomixer-4 Concrete

Project manager: Bjorn Hjartarson.

This is a field viscometer that measures rheological properties and blends of self-compacting concrete in a single process. The sponsor and partner is the Housing Financing Fund.

Coplate 5

Project manager: Jon Elvar Wallevik.

This is the development of the parallel plate system of Viscometer 5. Sponsors and partners are the Housing Financing Fund and Steyputækni ehf (ConTec).

Airless concrete with Icelandic aggregates

Project manager: Thorður I. Kristjansson.

Non-air-entrained, frost-resistant concrete with Icelandic aggregates is designed and tested. The sponsor and partner is the Housing Financing Fund.

RheoTruckmeter

Project manager: Olafur H. Wallevik.

This concerns development of an inbuilt viscometer in a concrete truck mixer and design of the most eco-friendly concrete in the world. Sponsors and partners are the Rannís Technical Development Fund, Steyputækni ehf (ConTec),Reykjavík University, Steypustöðin ehf., the Housing Financing Fund, Björgun ehf., Ready Mix Abu Dhabi (United Arab Emirates), Rescon Mapei (Norway) and Golden Bay Cement (New Zealand).

Effect of tensile strength and vibration on homogeneity of concrete

Project manager: Helgi Hauksson.

How pliable must concrete be when it is laid? The meld of fresh concrete is improved to ensure better durability after it has hardened. The sponsor and partner is the Concrete Commission.

New Icelandic borehole concrete mixture with new cement

Project manager: Sunna O. Wallevik.

This is a response to the closure of the cement factory at Akranes. It is highly probable that no more Icelandic cement will be manufactured, as Iceland Cement in Akranes stopped producing cement in 2012. Thus a new borehole cement blend must be redesigned with foreign cement for lining geothermal wells in Iceland. The sponsor and partner is Landsvirkjun’s Energy Research Fund.

Eco-friendly concrete with volcanic ash from Eyjafjallajökull

Project manager: Bjorn Hjartarson.

The load from Svaðbælisá river is utilized in eco-friendly concrete. The sponsor and partner is the Housing Financing Fund.

Polymer-cement concrete

Project manager: Sunna O. Wallevik.

This concerns development and observations on Icelandic polymer-cement concrete. The sponsor and partner is the Housing Financing Fund.

Computational materials science

Project manager: Jon Elvar Wallevik.

This involves computational materials science using OpenFOAM and computer modelling in super-computers where the flow dynamics of concrete is researched. Sponsors and partners are the Rannís Technical Development Fund and Steyputækni ehf (ConTec).

Standards on shrinkage in Icelandic concrete

Project manager:  Olafur H. Wallevik.

This involves research into the formation of fine cracks in Icelandic concrete, which could be the result of shrinkage. Is there more shrinkage in Icelandic concrete than in foreign concrete? The sponsor and partner is the Concrete Commission.

Technical research on concrete, aiming at high-strength concrete

Project manager:  Olafur H. Wallevik.

This concerns research into an extremely strong, thin concrete layer to repair worn asphalt roads. The sponsor and partner is the Concrete Commission.

Effect of air content on frost resistance for different grades of quality and open aggregates

Project manager: Olafur H. Wallevik.
