According to Zhang and Malhotra [34], the splitting tensile strength of high strength concrete incorporating SF is equivalent to high performance concrete, but lesser than RHA concrete at cement replacement level of 10% and water binder ratio of 0.4.
The correlations BC(1,4), DE[alpha](1,4), DE[beta](1,4), E[beta]D(4,1), E[alpha]D(4,1), and CB(4,1) show that both Rha residues are attached (1-4) to the following GalA residue in the chain.
Mixtures to which RHA and SF had been added presented contraction, unlike PS which presented the greatest expansion and a change in slope at ~503[degrees]C, suggesting further expansion of the sample over a narrow temperature range.
The fresh properties are given in Table 4 for all concrete mixtures incorporating RHA, FA, and GGBS; no bleeding or segregation was detected.
The major design variables for the concrete mixtures were water/binder (W/B) ratio (0.30-0.50), RHA content (030%), and air content (4-8%).
"It's not straightforward as far as the RHA is concerned," he added.
Geoff Dunning, RHA chief executive, said: "The news will certainly get a cautious welcome from UK hauliers.
