    Hydrothermal performance of pulverised fuel ash and the manufacture of autoclaved aerated concrete by Robert A. Carroll

    Published 1996
    “…Differences in the hydrothermal performance of the two PFA samples are evident, which cannot be explained by the bulk elemental composition. Ash fractions obtained from a centrifugal air classifier have different reactivities during autoclaving and can result in specimens with different compressive strengths. …”

    Durability of reinforced GGBS/FA geopolymer concretes by Thanh Nguyen

    Published 2017
    “…Moreover, 1% CO2 concentration seems to be aggressive to FA-based GC cured at 75 oC with a carbonated depth of more than 5 cm after 54 days, whereas in the natural condition, the carbonation depths of these samples were very low and similar to that of the high strength CEM I concretes after 147 days. …”

    A trade-off concept for lightweight concrete in chloride environments by D. Dunne, M.D. Newlands, Christian Christodoulou, Chris Goodier

    Published 2016
    “…Experimental work focused on concrete mixes with a fixed water/binder ratio of 0.50 and a constant total binder content of 330kg/m3. 28-day results indicate that with respect to aggregate influence, for CEM I only concrete, reduced concrete performance is obtained when replacing normal-weight aggregate with lightweight on a like-for-like basis. …”

    3D-printed limestone calcined clay cement concrete incorporating recycled plastic waste (RESIN8) by Adewumi John Babafemi, Chris Norval, John Kolawole, Suvash Chandra Paul, Kamoru Ademola Ibrahim

    Published 2024
    “…Furthermore, the use of LC2 in 3DPC causes the fresh material to be susceptible to increased deformation under sustained load, which can be improved with the addition of RESIN8. Incorporating 10 % RESIN8 into C- and LC-printed concrete systems reduced the workability by 3.8 % (CR) and 1.9 % (LCR) and enhanced buildability performance from 46 (C) to 59 (CR) and 74 (LC) to 90 (LCR) number of layers. …”

    Vibration analysis of various wooden ski cores using laser vibrometry by Michael Frisch, Niko Nagengast, Franz Konstantin Fuss

    Published 2024
    “…On the other hand, it is important that the ski adapts well to the ground in different snow conditions, which in turn is directly related to the bending and torsional stiffness. These properties can be measured on the ski with varying degrees of accuracy, for example with accelerometers, laser vibrometry, or with 3-point bending and torsion tests. …”

    Corrosion resistance of BS 8500 compliant concretes by D. Dunne, Christian Christodoulou, Chris Goodier, R. Yea

    Published 2015
    “…FA and GGBS were blended in binary combinations with the PC, at levels of 28% and 51% respectively. Two water/cement (w/c) ratios of 0.35 and 0.40 were investigated, together with total cementitious contents of 380kg/m3, representing typical structural reinforced concrete. …”

    Resistivity and water absorption of concrete by Chris Goodier, C. Xueting, Christian Christodoulou, D. Dunne, R. Yea

    Published 2015
    “…The results showed that increasing the PFA, GGBS or SF replacement contents significantly increased both the surface and bulk resistivity of the concrete (e.g. with the 70% GGBS replacement, up to 9 times greater when compared to the control concrete). …”

    A case study of a hypothetical 100 MW OTEC plant analyzing the prospects of OTEC technology by Subhashish Banerjee, L. Duckers, Richard Blanchard

    Published 2015
    “…Hydrogen production, as may be made at expense of the net power generated, from a 100 MW plant, would amount to over 35,000 kg/day or 20,000 kg of NH3/day. 21,773 kg of CO2/day from OC-OTEC (also from the hybrid type but not for CC-OTEC) would be available, which can be utilized as raw material for soda ash manufacture/urea production (along with NH3 as may be availed from H2 production). …”

    Effect of various mix parameters on the true tensile strength of concrete by Hamid Reza Azizipesteh Baglo

    Published 2013
    “…The tensile strength of concrete has traditionally been expressed in terms of its compressive strength (e.g. ft = c × c f ). Based on this premise, extensive laboratory testing was conducted to evaluate the tensile strength of the concretes, including the direct tension test and the indirect cylinder splitting and MOR tests. …”
