High-strength lightweight concrete and preparation method thereof
The invention relates to the technical field of preparation of novel concrete, and provides high-strength lightweight concrete and a preparation method thereof. The lightweight concrete comprises the following components: cement, ceramsite, fly ash, quick lime, gypsum, polyvinyl alcohol fibers, a naphthalene water reducer, water and a reinforced aerogel complex. According to the reinforced aerogel complex, silicon dioxide aerogel is reinforced and modified through carbon aerogel fibers, the compressive strength of the silicon dioxide aerogel is improved, the carbon aerogel fibers and the silicon dioxide aerogel are both aerogel materials with very low density, the defect that the density is increased due to the fact that common fiber reinforced aerogel is adopted is overcome, and the concrete material with light weight and high strength performance can be obtained.
本发明涉及新型混凝土的制备技术领域，提供了一种高强度的轻质混凝土及制备方法。所述轻质混凝土的组分包括水泥、陶粒、粉煤灰、生石灰、石膏、聚乙烯醇纤维、萘系减水剂、水、增强气凝胶复合体。所述增强气凝胶复合体是采用碳气凝胶纤维对二氧化硅气凝胶进行增强改性，提高了二氧化硅气凝胶的抗压强度，并且碳气凝胶纤维与二氧化硅气凝胶均是密度很低的气凝胶材料，克服了采用普通纤维增强气凝胶造成密度增大的缺陷，可获得兼具轻质和高强度性能的混凝土材料。
