Abstract

The invention provides lightweight high-strength waterproof concrete and a preparation method thereof, and belongs to the field of concrete. The lightweight high-strength waterproof concrete comprisesthe following components in parts by mass: 450 to 500 parts of Portland cement, 130 to 160 parts of mineral powder, 130 to 160 parts of fly ash, 70 to 80 parts of silica fume, 60 to 85 parts of glassmicro-beads, 16 to 18 parts of steel fibers, 180 to 210 parts of iron tailing sand, 350 to 400 parts of pore-sealing fly ash ceramsite, 180 to 200 parts of water, 15 to 25 parts of a water reducing agent and 4 to 5 parts of a permanent solidification liquid RMO. The pore-sealing fly ash ceramsite is prepared by a method comprising the following steps: immersing fly ash ceramsite into a mixed solution of RMO and water, pre-wetting, draining off water after 1 hour, and then carrying out coating treatment by using a mixture of Portland cement and iron tailing sand powder, so as to obtain the pore-sealing fly ash ceramsite. The concrete disclosed by the invention has the properties of light weight, high strength and water resistance.

Description

technical field

[0001] The invention relates to the technical field of concrete, in particular to a lightweight high-strength waterproof concrete and a preparation method thereof. Background technique

[0002] With the rapid development of my country's construction industry, building materials must have the characteristics of fire resistance and earthquake resistance while having excellent strength. Due to the above advantages, lightweight concrete has been widely used in the construction field. However, at present, lightweight concrete There are still problems such as low strength, poor water resistance and durability, and uneven distribution of lightweight aggregates, so it is necessary to further improve the performance of lightweight concrete. Coarse aggregate in lightweight concrete is prepared from lightweight aggregate, and the cylinder compressive strength of lightweight aggregate is low, and the low cylinder compressive strength causes the strength level of lightweig...
