Lignin fiber lightweight high-strength ceramsite concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses lignin fiber lightweight high-strength ceramsite concrete and a preparation method thereof. A preparation method of lignin fiber lightweight high-strength ceramsite concrete comprises the following steps: soaking ceramsite in water, performing wetting treatment, adding a lightweight material into the wetted ceramsite, and uniformly mixing to obtain lightweight ceramsite; light ceramsite and anti-crack fibers are mixed, a primary mixture is obtained, and the anti-crack fibers comprise lignin fibers, quaternary ammonium salt preservatives and organic amine preservatives; mixing and stirring the cement, the natural sand, the water reducing agent and the floating beads to obtain a medium mixture; and stirring the primary mixture and the medium mixture to obtain the lignin lightweight high-strength ceramsite concrete. The ceramsite concrete has the advantages of light weight and high strength; in addition, the preparation method has the advantages that the tensile strength and toughness of the ceramsite concrete are improved, and the high brittleness of the ceramsite concrete is reduced.
本申请涉及混凝土技术领域，具体公开了一种木质素纤维轻质高强陶粒混凝土及其制备方法。一种木质素纤维轻质高强陶粒混凝土的制备方法，包括以下步骤：将陶粒浸水，进行润湿处理，向润湿处理后的陶粒中加入轻质材料，混合均匀后，得到轻质陶粒；将轻质陶粒和抗裂纤维混合，得到初混料，所述抗裂纤维包括木质素纤维、季铵盐类防腐剂和有机胺类防腐剂；将水泥、天然砂、减水剂和漂珠进行混合搅拌，得到中混料；将所述初混料与所述中混料进行搅拌，得到木质素轻质高强陶粒混凝土。本申请的陶粒混凝土具有轻质高强的优点；另外，本申请的制备方法具有提高陶粒混凝土的抗拉强度和韧性，降低陶粒混凝土的高脆性的优点。
