用能降低水冻结温度的化合物拌合混凝土混合物的原理去研究如何进一步改善用非加热法浇灌混凝土时,首先要研究出混凝土外加剂使用效果的主要规律。这类外加剂能够改变:拌和水的物理化学性质水泥颗粒的电动力学性质;原相和新生成相的溶解度;水化生成物的相的成分。由于考虑到混凝土硬
With the principle of compound mixing concrete mixtures that can reduce the freezing temperature of water to study how to further improve the method of pouring concrete with non-heating method, we must first study the main rules of the effect of concrete admixtures. Such admixtures can change: the physicochemical properties of the mixing water; the electrokinetic properties of the cement particles; the solubility of the original phase and the newly formed phase; the composition of the phases of the hydration product. Due to considering the hard concrete
