Abstract
A lightweight aggregate-based non-steam-cured high-performance pipe culvert and a preparation method thereof. The lightweight aggregate-based non-steam-cured high-performance pipe culvert is prepared from a raw material including the following components by mass per unit volume: 300-450 kg/mof a low-carbon sulfur-aluminum-ferric cementitious material; 800-920 kg/mof a solid waste-based lightweight aggregate; 300-550 kg/mof a solid waste-based artificial sand; 0-100 kg/mof a mineral admixture; 0-50 kg/mof an auxiliary material; and 110-160 kg/mof water; and the lightweight aggregate-based non-steam-cured high-performance pipe culvert further includes a water reducer and a retarder. The lightweight aggregate-based non-steam-cured high-performance pipe culvert of the present invention can be demolded within 4 hours during forming, with short demolding time and no need for steam curing, resulting in a low production cost and high production efficiency. The obtained product has high strength, good impermeability and durability, and can utilize solid waste in a high proportion.
