The invention relates to a baking-free
brick which is prepared from the following raw materials in parts by weight: 30-45 parts of waste
asphalt concrete, 10-15 parts of regenerated
glass fiber reinforced plastic fibers, 15-20 parts of
fly ash and 15-20 parts of
lime powder. The baking-free
brick is prepared by taking the waste
asphalt concrete and the regenerated
glass fiber reinforced plastic fibers as main materials, taking the
fly ash and the
lime powder as auxiliary materials, adding 15-20 parts of water, stirring and mixing, and carrying out
compression molding and steam curing. The preparation method comprises the following steps of: crushing and sieving the waste
asphalt concrete;
cutting and crushing
glass fiber reinforced plastic plate-shaped waste to obtain glass
fiber reinforced plastic regenerated
powder and glass
fiber reinforced plastic regenerated fibers; adding water into the treated waste
asphalt concrete, the treated regenerated glass
fiber reinforced plastic fibers, the
fly ash and the
lime powder according to the proportion, stirring, and mixing well to obtain a mixture; weighing the mixture and pressing the mixture into a green
brick; and performing steam curing on the prepared green brick, and cooling to obtain the baking-free brick. The prepared baking-free brick is more compact in structure, and the average
compressive strength and the
breaking strength are further improved.
