Abstract: Provided are a nano-titanium dioxide (NT)/biochar (BC) composite, and a preparation method and use thereof, which belong to the technical field of cement-based materials. NT is introduced into a porous structure of the micron-sized BC, which not only addresses the high aggregation of NT, but also reduces Ca(OH)2 size and crystal growth orientation through effects such as filling and nucleation brought by NT in the porous structure of BC. In this way, more C—S—H gels are generated to fill the pores, thereby improving an interfacial transition zone (ITZ), which enhances the mechanical properties such as compressive strength and flexural strength. The NT/BC composite of the disclosure is doped into a cement-based material, which allows that in a surface layer of the cement-based material, CO2 absorption capacity could be improved through carbon sequestration properties and the porous structure of the composite, and the carbonization of the surface layer could be accelerated by hydration accelerating properties of the NT to form a calcium carbonate surface protective layer, thereby improving durability of the cement-based material.

Abstract: The present invention discloses a same-cavity integrated vertical high-speed multistage superfine pulverizing device and method for walnut shells. The same-cavity integrated vertical high-speed multistage superfine pulverizing device for walnut shells includes a double-channel sliding type feeding device and a same-cavity integrated vertical pulverizing device. The same-cavity integrated vertical pulverizing device includes a material lifting disc and a same-cavity integrated vertical pulverizing barrel. A first-stage coarse crushing region, a second-stage fine crushing region, a third-stage pneumatic impact micro pulverizing region and a fourth-stage airflow mill superfine pulverizing region are disposed in the same-cavity integrated vertical pulverizing barrel. Walnut shells falling through the double-channel sliding type feeding device are uniformly lifted by the material lifting disc to a wedge-shaped gap of the first-stage coarse crushing region to be coarsely crushed, and coarsely crushed materials are finely crushed by the second-stage fine crushing region through a two-stage wedge-shaped direct-through gradually reducing gap. The third-stage pneumatic impact micro pulverizing region performs high-speed collision on finely crushed walnut shell particles, and walnut shell fine particles are carried by a high-speed airflow and are collided and violently rubbed to be pulverized. The microparticle grading is realized by the fourth-stage airflow mill superfine pulverizing region by using arc-shaped blades, and microparticles conforming to a particle size condition are attracted out through negative pressure attraction.
