Application method of limestone ultrafine powder in cement concrete
The invention discloses an application method of limestone ultrafine powder in cement concrete. The limestone ultrafine powder and the modified ultrafine fly ash are uniformly mixed and applied to the cement concrete, and the mass ratio of the limestone ultrafine powder to the modified ultrafine fly ash is (5-7): (2.5-3). According to the invention, the limestone powder fine particles are uniformly distributed in the base phase of the cement paste according to a reasonable adding proportion, so that a micro-aggregate effect can be achieved, a good densification effect is achieved, the void volume in the concrete is reduced, and capillary channels in the paste are filled, so that the concrete structure is densified, and the strength of the concrete can be improved.
本发明公开了一种石灰石超细粉在水泥混凝土中的应用方法。将石灰石超细粉以及改性超细粉煤灰混合均匀应用于水泥混凝土中，且所述石灰石超细粉与改性超细粉煤灰的质量比为5‑7：2.5‑3。本发明通过合理的添加比例，石灰石粉微细颗粒均匀分布于水泥浆体的基相之中，能够起到微集料作用，具有良好的致密作用减少了混凝土中空隙体积，填塞了浆体中的毛细通道，从而使得混凝土结构致密化，能够提高混凝土强度。
