The invention discloses high-performance lightweight concrete, and relates to the field of concrete, and the high-performance lightweight concrete is prepared from the following components by weight: 60-90 parts of fine aggregate; 180 to 220 parts of light coarse aggregate; 140 to 160 parts of cement; 30 to 40 parts of water; 3-5 parts of a water reducing agent; 0.7 to 1.2 parts of modified bamboo fiber; a preparation method of the modified bamboo fiber comprises the following steps: S1, preparing hydroquinone and triethylene tetramine into a mixed aqueous solution to obtain a modified solution; s2, adding bamboo fibers into the modified liquid, stirring for 1-4 hours at 23-28 DEG C, filtering, collecting solid substances, washing and drying to obtain coated bamboo fibers; and S3, mixing the coated bamboo fibers with a silane coupling agent aqueous solution, stirring at 45-55 DEG C for 2-4 hours, filtering, collecting solid substances, washing and drying to obtain the modified bamboo fibers. The lightweight concrete has the effect of improving the compressive strength, the splitting tensile strength and the thermal insulation performance of the lightweight concrete.
本申请公开了一种高性能轻质混凝土，涉及混凝土领域，其由包括以下重量份的组分制备得到：细骨料60‑90份；轻质粗骨料180‑220份；水泥140‑160份；水30‑40份；减水剂3‑5份；改性竹纤维0.7‑1.2份；所述改性竹纤维的制备方法如下：S1、将对苯二酚、三乙烯四胺制备成混合水溶液，得到改性液；S2、将竹纤维加入改性液中，在23‑28℃条件下搅拌1‑4h，过滤并收集固体物质，洗涤后干燥，得到包膜竹纤维；S3、将包膜竹纤维与硅烷偶联剂水溶液混合，在45‑55℃条件下搅拌2‑4h，过滤并收集固体物质，洗涤后干燥，得到改性竹纤维。本申请具有提高轻质混凝土的抗压强度、劈裂抗拉强度和保温性能的效果。
