The invention provides a method for improving concrete strength. The method comprises the following steps of: (1) weighing raw materials including cement, coarse aggregate, fine aggregate, water and admixtures; (2) preparing slurry: adding the cement and the admixtures into a concrete stirrer in sequence to be evenly stirred, and then, adding half of water to be mixed into even slurry; and (3) adding the coarse aggregate and the fine aggregate into the slurry, meanwhile, slowly adding a residual quantity of water, and continuously evenly stirring, wherein the admixtures include the following raw materials: coal ash, silica fume and slag powders. The method has the beneficial effect of improving the concrete strength, and is suitable for the field of concrete preparation.
本发明提供的一种提高混凝土强度的方法，包括以下步骤：（1）称取原料：水泥、粗骨料、细骨料、水和掺合料；（2）制备浆体：将水泥和掺合料依次加入混凝土搅拌机内搅拌均匀，然后加入一半水，混合成均匀的浆体；（3）向浆体中加入粗骨料和细骨料，同时缓慢加入剩余量的水，继续搅拌均匀即可；所述掺合料中包括以下原料：粉煤灰、硅灰和矿渣粉；本发明具有提高混凝土强度的有益效果，适用于制备混凝土的领域。
