Coal-gangue lightweight aggregate concrete
Disclosed coal-gangue lightweight aggregate concrete is prepared by mixing water, cement, coal gangue aggregate, coal gangue sand, a water reducer and silica fume, the coal gangue aggregate is coal gangue large-particle-size composition, and the coal gangue sand is prepared coal gangue small-particle-size composition. The coal-gangue lightweight aggregate concrete possesses characteristics of being lightweight, high in strength, warm-keeping, fireproof and the like, is good in deformabiity, low in elastic modulus and relatively large in shrinkage and creep in an ordinary way, and is capable of reducing basic load, thereby reducing the whole building deadweight. According to the technical scheme, a large amount of coal gangue which is generated by coal mine and possesses pollution property is changed into valuables from waste, and is effectively applied to road paving and other municipal and building construction, and environment pollution is reduced.
