Digital aluminate concrete preparation method and digital aluminate concrete mix proportion
On the basis of a digital concrete model, the concrete strength increase rule is further discovered, so that the aluminate concrete preparation method directly spans from an empirical method to a digital preparation method. According to the Wang's sieve, the proportion of sieve pores conforms to the filling rule of aggregates; and if the density of the concrete or asphalt mixture prepared by screening the aggregate is higher, the void ratio is lower, the strength is higher, and the durability is higher. According to the invention, the refractory concrete mixture has set workability and is easier to construct; after molding, the strength, refractoriness and volume fixity are known to be controllable and adjustable before construction, and the thermal shock stability, refractoriness under load, high-temperature corrosion resistance and high-temperature corrosion resistance are further improved; and the refractory applicable temperature is increased. According to the invention, the low-alumina cement and the medium-alumina cement can be used for preparing aluminate (refractory) concrete with high refractoriness, high thermal shock stability and high refractoriness under load, so thatthe application range of the aluminate concrete prepared from the medium-alumina cement and the low-alumina cement is expanded, and the preparation cost is reduced.
本发明以数字化混凝土模型为基础，通过对混凝土强度增长规律的进一步发现，使铝酸盐混凝土配制方法从经验法直接跨越到数字化配制方法。本发明王宋氏筛，筛孔间比例符合集料间的填充规律；筛分集料配制的混凝土或者沥青混合料密度更大，空隙率更低强度更高，耐久性更长。本发明使耐火混凝土拌和物具有设定工作性，施工更容易；成型后各温度下强度、耐火度、体积固定性将在施工前先知可控可调，热震稳定性、荷重软化温度、抗高温侵蚀能力、抗高温侵蚀能力进一步提高；提高耐火适用温度。本发明使低、中铝水泥可用以配制高耐火度、高热震稳定性、高荷重软化温度铝酸盐(耐火)混凝土，扩大了中、低铝水泥配制的铝酸盐混凝土适用范围，降低配制成本。
