^aN55 was produced with normal-weight aggregates. W and D samples used wet and dried lightweight aggregates, respectively. The last two digits are w/b in percentage.
^bLWA content accounts for the weight of the water absorbed in them (15.4% by mass) while the mixing water content is constant for all mixes.
