Lightweight high-strength concrete and preparation method thereof

Abstract

The invention belongs to the field of concrete preparation, and particularly relates to lightweight high-strength concrete and a preparation method thereof.The lightweight high-strength concrete comprises a supporting device, a processing cylinder is arranged in the supporting device, the inner wall of the supporting device is movably connected with the bottom of the processing cylinder, and a power source is arranged at the top of the processing cylinder; the top of the processing barrel is movably connected with the bottom of the power source, a sealing device is arranged over the power source, the bottom of the sealing device is movably connected with the top of the processing barrel, the sealing device comprises a sealing cover, supporting rods are evenly arranged at the top of the sealing cover, and the top of the sealing cover is fixedly connected with the bottoms of the supporting rods; a protective ring is arranged at the top of the supporting rod, and the top of the supporting rod is fixedly connected with the outer surface of the protective ring, aiming at the defects in the prior art, the invention provides the light high-strength concrete and the preparation method thereof, and the problem that a small amount of concrete cannot be well prepared when traditional concrete is used for repairing work is solved.

Description

technical field [0001] The invention belongs to the field of concrete preparation, in particular to a lightweight high-strength concrete and a preparation method thereof. Background technique [0002] With economic development, the process of urban spongeization is getting faster and faster. Road planning plays a very important role in urban construction. Most of the traditional pavements are impermeable pavements, which are easy to accumulate water and reduce comfort, which not only affects the strength of the pavement itself. At the same time, it will also affect people's travel because of the road surface and water, which will bring great inconvenience to people's travel and negative impact on the ecological environment. The strength performance of concrete pavement will balance the internal porosity as much as possible. If the porosity is too large, although the water permeability can be guaranteed, it will inevitably lead to a decrease in strength; and light and high-st...
