Lightweight aggregate concrete
The invention discloses a lightweight aggregate concrete. The lightweight aggregate concrete comprises, by mass, 470-480 kg/m<3> of 525 cement, 50-56 kg/m<3> of silica fume, 60-64 kg/m<3> of stone, 580-590 kg/m<3> of fly ash ceramsite, 105-112 kg/m<3> of shale ceramsite, 150-260 kg/m<3> of fly ash pottery sand, 160-268 kg/m<3> of standard sand, 93-123 kg/m<3> of pottery sand, 120-130 kg/m<3> of water, 0.08-0.12 mass% of nano silicon dioxide, and 0.14-0.18 mass% of a polycarboxylic acid high-performance water reducing agent . According to the invention, fly ash ceramsite with relatively high cylinder compressive strength and relatively low apparent density is selected to redesign the mix proportion of the lightweight aggregate concrete, so that the strength of the lightweight aggregate concrete is ensured to be greater than or equal to 60 MPa; and the density is less than or equal to 1850 g/cm<3>.
本发明公开了一种轻骨料混凝土，包括以下各组分：525水泥470～480kg/m3，硅灰50～56kg/m3，石块60～64kg/m，粉煤灰陶粒580～590kg/m3，页岩陶粒105～112kg/m3，粉煤灰陶砂150～260kg/m3,标准砂160～268kg/m3，陶砂93～123kg/m3，水120～130kg/m3，纳米二氧化硅和聚羧酸高性能减水剂，其中纳米二氧化硅在配方中质量百分比为0.08～0.12％，聚羧酸高性能减水剂在配方中质量百分比为0.14～0.18％。本发明选用筒压强度较高和表观密度较低的粉煤灰陶粒重新设计轻骨料混凝土的配合比，从而确保轻骨料混凝土的强度≥60MPa；密度≤1850g/cm3。
