A discussion of “Influence of fibrous additives on properties of aerated autoclaved concrete forming mixtures and strength characteristics of products” by A. Laukaitis, J. Kerienė et al. [Construction and Building Materials 23 (9) (2009) 3034–3042]

This discussion focuses on the feasibility of using non-hydrophilized and hydrophilized carbon, polypropene, basalt and kaoline fiber to reinforce the aerated autoclave concrete (AAC). It is shown that the four kinds of fibers are not appropriate for reinforcing AAC on the account of high thermal conductivity, no resisting alkali or high temperature, although they are appropriate for reinforcing concrete.
