Low-water-absorption modified waste brick, preparation method thereof and sound insulation mortar
The invention belongs to the technical field of building materials and relates to a low-water-absorption modified waste brick, a preparation method thereof and sound insulation mortar The preparation method of the low-water-absorption modified waste brick comprises the following steps of: putting a pretreated waste brick into an alkaline solution for dipping the pretreated waste brick, then adding hydrophobic white carbon black into the alkaline solution, continuing dipping, taking out a product and drying the product to prepare a waste brick intermediate; and soaking the waste brick intermediate in an aqueous solution of a film-forming material, taking out, and drying a product to obtain the low-water-absorption modified waste brick. The waste brick is modified and reinforced in advance, so that the water absorption rate of the waste brick is effectively reduced; the technical barrier that the waste brick is applied to mortar is overcome; and mortar with good workability, mechanical property and sound insulation effect can be prepared.
本发明涉及建筑材料技术领域，特别涉及吸水率低的改性废砖及其制备方法和隔声砂浆。所述吸水率低的改性废砖的制备方法，包括以下步骤：将预处理后的废砖置于碱性溶液中浸渍，然后于所述碱性溶液中添加疏水型白炭黑，继续浸渍，取出后干燥，制备废砖中间体；将所述废砖中间体置于成膜材料的水溶液中浸泡，取出后干燥，得吸水率低的改性废砖。通过预先对废砖进行改性和强化处理，有效降低了废砖的吸水率，克服了废砖应用于砂浆中的技术壁垒，有利于制备出工作性、力学性和隔声效果好的砂浆。
