The invention relates to high-strength lightweight concrete which is characterized by being prepared from the following components in parts by weight: 200 to 230 parts of Portland cement, 160 to 180 parts of mineral powder, 140 to 160 parts of fly ash, 30 to 50 parts of floating beads, 40 to 60 parts of rubber particles, 220 to 260 parts of ceramsite, 300 to 350 parts of pottery sand, 10 to 13 parts of a water reducing agent, 3.5 to 5.5 parts of an exciting agent, 5.5 to 8.5 parts of a tackifier and 160 to 180 parts of water. The invention also provides a preparation method of the concrete. Portland cement, mineral powder and fly ash are mixed to obtain a cementing material for later use; mixing ceramsite with pottery sand to obtain lightweight aggregate for later use; the high-strength lightweight concrete is prepared by adding the lightweight aggregate into the cementing material, uniformly stirring, and adding the high-performance reducing agent, the exciting agent, the tackifier and the water. On the basis of adopting ceramsite and pottery sand with lower specific gravity as aggregate, the strength of the concrete is ensured by adopting superfine mineral powder and a high-efficiency exciting agent, and the volume weight of the concrete is reduced on the basis of maintaining the performance of the concrete, so that the purposes of high strength and light weight are achieved.
本发明涉及一种高强轻质混凝土，其特征在于：以重量份数计，包括以下组分：硅酸盐水泥200～230份、矿粉160～180份、粉煤灰140～160份、漂珠30～50份、橡胶颗粒40～60份、陶粒220～260份、陶沙300～350份、减水剂10～13份、激发剂3.5～5.5份、增粘剂5.5～8.5份、水160～180份。同时本申请提供了一种混凝土的制备方法，将硅酸盐水泥、矿粉、粉煤灰混合得到胶凝材料备用；将陶粒和陶沙混合，得到轻质骨料备用；将轻质骨料加入到胶凝材料中，搅拌均匀后，并添加高性能减少剂、激发剂、增粘剂和水配制成高强轻质混凝土。在采用比重较低的陶粒和陶沙作为骨料的基础上，采用超细矿粉和高效激发剂来保证混凝土的强度，在保持混凝土性能的基础上，降低混凝土的容重，从而达到高强轻质的目的。
