Abstract
The invention discloses a low-density aerated concrete product and a preparation method thereof, and belongs to the technical field of building materials. The preparation method adopting quartz micro powder and iron core tailing, which are respectively 25%-35% and 30%-40% of a dry material, as the primary materials comprises the following steps of: adding cement and lime for cementing; initiating by aluminum powder; and adjusting the component proportion and the steam-curing environment to prepare a light high-strength aerated concrete product with desiccated bulk density of 300kg/m<3>-525kg/m<3> and absolute-dry compressive strength of 2.0 MPa-3.0 MPa. According to the preparation method disclosed by the invention, low-carbon, environment-friendly and energy-saving production concept is adopted, and the quartz micro powder and iron ore tailing, which are discarded after quartz sand ore-dressing, are adopted as the primary materials for producing the low-density autoclaved aerated concrete product as the wall self-insulation material.
