The invention discloses a high-strength foamed cement block and a preparation method thereof. The high-strength foamed cement block comprises the following components, by mass: 2.2-3.0% of a reinforcing agent, 25-37% of an admixture, 0.05-0.10% of a vegetable protein foaming agent and 0.13-0.17% of HPMC (Hydroxy Propyl Methyl Cellulose) according to the mass ratio of P.O 42.5 ordinary Portland cement. According to the preparation method, a large amount of coal gangue, silica fume and chemical gypsum can be utilized, certain environmental protection benefits are achieved, the dry density of theprepared foamed cement block is 700 +/-30 kg/m <3>, the compressive strength is 8.0+/-0.3MPa and is higher than the strength of the foamed cement block under the same density, the performance of thefoamed cement block meets the requirements of FCB A 7.5 B 07 in JC/T 1062-2007, and a certain bearing effect is realized.
本发明公开了一种高强度发泡水泥砌块及其制备方法，按照P.O 42.5普通硅酸盐水泥质量比计如下：包括2.2‑3.0％增强剂、25‑37％掺合料、0.05‑0.10％植物蛋白发泡剂、0.13‑0.17％HPMC。该制备方法可大量利用煤矸石、硅灰以及化学石膏，具有一定的环保效益，其制备出的发泡水泥砌块干密度700±30kg/m3级，抗压强度8.0±0.3MPa，高于同级别密度下的发泡水泥砌块强度，其性能符合JC/T 1062‑2007中FCB A 7.5 B 07的要求，具有一定的承重效果。
