Fly ash – Limestone Synergy in Ternary Cements. FA 1 Environmentally friendly concrete. SP 1.1 Low carbon-footprint binder systems
(COIN Project report;46, Research report, 2013)The objective is to study the parameters of cements and fly ashes in combination with limestone that would optimize the synergistic chemical reaction between fly ash and limestone that leads to more bound water and thereby ... -
Characterisation of fillers < 0.125 mm used in Case Study Velde
(COIN Project report;61, Research report, 2015)The zeta potentials of five different fillers and three commercial plasticizers were explored in this report. The main purpose was to determine how these materials interact with each other to aid dispersions, in an effort ... -

(COIN Project report;56, Research report, 2015)One of the objectives of COIN's Focus Area 3.1 Crackfree concrete structures is to develop guidelines for recommended mix design for different types of structures subjected to restrained thermal dilation and autogeneous ... -
Round Robin Test program on Energy Absorption Capacity of Round Panels according to Norwegian Concrete Associations Publication no 7:2011
(COIN Project report;48, Research report, 2013)A Round-Robin test program (inter-laboratory study) on energy absorption capacity of round panels is presented. The panels were tested according to the procedure described in Norwegian Concrete Associations Publication no. ... -
Characterisation of concrete surfaces in Askimporten tunnel: COIN project report 45 - 2012
(COIN Projet report;45, Research report, 2012)This report gives the findings from a collaboration project between the Norwegian Public Roads Administration (NPRA) and the COIN FA 2.1 project managed by SINTEF Building and Infrastructure which was start in spring ... -
Confinement effect of fibres on the behaviour of lightweight aggregate concrete beams
(COIN Project report;67, Research report, 2015)This study focuses on ductility of lightweight aggregate concrete (LWAC) in compression. The major disadvantage of LWAC is the brittleness in compression at the material level compared to normal density concrete. Requirements ... -
Microstructure of clinker – fly ash interactions
(COIN Project report;69, Research report, 2015)The first objective was to find out why a white clinker from previous studies has a higher strength potential than the other 3 clinkers tested in the same study, as well as finding out whether or not it contains other ... -
Experimental study on flexural ductility in over-reinforced lightweight aggregate concrete beams : FA 3 Aesthetics and technical performance SP 3.3. Structural Performance
(COIN Project report;70, Research report, 2013)This study focuses on ductility of lightweight aggregate concrete (LWAC) in compression. The major disadvantage of LWAC is the brittleness in compression at the material level compared to normal density concrete. Requirements ... -
Stability of SCC – robustness for changes in water content and sand grading. FA 2 Competitive constructions. SP 2.1 Robust highly flowable concrete
(COIN Project report;47, Research report, 2013) -
Alternative binders based on lime and calcined clay
(COIN Project report;68, Research report, 2015)Alternative binders are in this report defined as binders without Portland cement. In this particular project it will be based on calcined clay or fly ash as a source of reactive silica and alumina in combination with lime ... -
Hardening accelerators for fly ash blended cement. FA 1 Environmentally friendly concrete. SP 1.1 Low carbon-footprint binder systems
(COIN Project report;71, Research report, 2015)A former developed hardening accelerator for fly ash blended cement should be replaced with another formulation free from thiocyanate and preferentially with equal or better performance in terms of compressive strength. ... -
Structural FRC – Design approach and experimental results. FA 2 Competitive construction. SP 2.2 Ductile high tensile strength concrete
(COIN Project report;66, Research report, 2015) -
Review report on dry and wet classification of filler materials for concrete : State-of-the-art : FA 2.3 High quality manufactured sand for concrete : SP 2.3.1 Filler technology
(COIN Project report;52, Research report, 2014)Due to depletion of natural sand resources in many central locations, it is an increased production and utilisation of crushed sand for concrete purposes. This crushed and processed sand is referred to as; Manufactured ... -
Workshop on Moisture in Concrete, Trondheim, Norway 6–7 February 2012. Measurement of moisture and relative humidity in concrete. FA 3 Technical performance. FA 3.2 Service life
(COIN Projet report;81, Research report, 2016) -
Practical methods to assess segregation risk of SCC on site. FA: Competitive constructions SP 2.1 Robust and highly flowable concrete with controlled surface quality
(COIN Project report;59, Research report, 2015)Many of the suggested methods for testing of SCC stability are quite demanding in execution and therefore seldom used in field. Furthermore, questions have been raised about how well they represent the stability problems ... -
A preliminary study on using manufactured sand from Jelsa Quarry for the production of plastic concrete mixes. FA 2 Competitive constructions. SP 2.3 High quality manufactured sand for concrete
