Quick-setting early-strength concrete admixture, quick-setting early-strength concrete and preparation process of quick-setting early-strength concrete
The invention relates to quick-setting and early-strength concrete, in particular to a quick-setting and early-strength concrete admixture, quick-setting and early-strength concrete and a preparation process thereof.The quick-setting and early-strength concrete admixture comprises an exciting agent and an early-strength agent, and the exciting agent is composed of limestone, bauxite, fluorite and gypsum according to the mass ratio of (4-6): (1-2): (3-5): (2-3); the preparation method of the admixture comprises the following steps: 1) respectively crushing the limestone, the bauxite, the fluorite and the gypsum into powder, and jointly mixing the powder to prepare mixed powder; mixing the mixed powder with water to prepare a premix; the mass ratio of the water to the mixed powder is (1-2): (2-5); the preparation method comprises the following steps of 1) preparing a premix, 2) preparing calcined balls from the premix prepared in the step 1), and calcining the calcined balls at 1200-1300 DEG C for 30-40 min to prepare an activator, and 3) mixing an early strength agent and the activator prepared in the step 2) together to obtain the quick-setting early-strength concrete. The preparation method has the advantage of improving the compressive strength of the quick-setting early-strength concrete.
本发明涉及快凝早强混凝土的，特别涉及一种快凝早强混凝土外加剂、快凝早强混凝土及其制备工艺，包括激发剂和早强剂，激发剂由石灰石、铝矾土、萤石、石膏按照质量比（4‑6）:（1‑2）:（3‑5）:（2‑3）组成；外加剂的制备方法包括如下步骤：1）：将石灰石、铝矾土、萤石和石膏分别粉碎成粉料，将各个粉料共同混合制备成混合粉料；将混合粉料与水混合，制备成预混料；水与混合粉料的质量比为（1‑2）:（2‑5）；2）：将步骤1）中制得的预混料制备成煅烧球，在1200‑1300℃的温度下煅烧30‑40min，制得激发剂；3）：将早强剂与步骤2）中制得的激发剂共同混合，即得。本申请具有提高快凝早强混凝土的抗压强度的优点。
