Preparation method of high-temperature-resistant concrete
The invention discloses a preparation method of high-temperature-resistant concrete, and belongs to the technical field of concrete.The preparation method of the high-temperature-resistant concrete comprises the following steps that firstly, raw materials are sampled and detected, and then part of the raw materials are cleaned for standby application; step 3, adding broken stones into the first mixture, and stirring, so as to obtain a second mixture. According to the preparation method of the high-temperature-resistant concrete, the stable service life of the concrete at the high temperature of 750 DEG C can be realized, the problems of excessive thermal expansion and cracking are avoided, the quality and the structural strength in the whole service life are ensured to the greatest extent, the initial setting time and the final setting time can be ensured by adopting the additives, and the concrete can be ensured to be stable in hot working days. And stable transportation can still be achieved, solidification in the transportation equipment is avoided, and the transportation efficiency is improved.
本发明公开了一种耐高温的混凝土制备方法，属于混凝土技术领域，该耐高温的混凝土制备方法，包括以下步骤：步骤一、对原材料进行抽样检测，随后对部分原材料进行清洗，待用，步骤二、将粉煤灰、矿粉与砂进行初步混合，搅拌后制得第一混合物，步骤三、第一混合物加入碎石进行搅拌，获得第二混合物。该耐高温的混凝土制备方法，可以实现750℃高温下，混凝土稳定的使用寿命，避免产生过度的热膨胀和开裂问题，最大程度保证全寿命内的质量和结构强度，且采用外加剂，可以保证其初凝和终凝的时间，保证在较热的工作日内，依然可以实现稳定的运输，避免产生运输设备内部的凝固，提高运输的高效。
