The invention belongs to technical field of concrete, especially a kind of weight concrete；Its mass parts composition includes: iron ore 1,800 2200 parts, iron ore 1,000 1200 parts, cement 300 400 parts, additive 46 parts, 120 180 parts of water, corrosion inhibitor 58 parts；The weight concrete unit weight up to unit weight of the present invention can reach 3800 ~ 3900 Kg/m 3 , cost situation is moderate, and has obvious advantage at relatively common concrete of aspect such as durability, workability, wearability, bearing capacitys；The weight concrete price of the present invention is less than the price of essence iron ore, moderate cost；The corrosion inhibitor resistance rust efficiency added in the present invention reaches 95%, can delay weight concrete corrosion initial time more than one times, is greatly improved engineering service life.Concrete performance is had no adverse effect by organic corrosion inhibitor, slightly can improve concrete strength in early days. |
