Description
Technical Field
The invention belongs to the technical field of building materials, and particularly relates to light high-strength lightweight aggregate concrete and a pouring method thereof.
Background
Modern buildings develop towards high-rise and large-span directions and simultaneously put higher requirements on comfort functions such as quiet environment and proper temperature, so that modern civil engineering needs novel building materials with light weight, high strength, heat preservation, heat insulation and sound insulation, and light aggregate concrete is a material with the potential. Lightweight aggregates are key factors that determine the performance of lightweight aggregate concrete. The traditional light coarse aggregate mainly comprises expanded perlite, shale ceramsite, clay ceramsite, fly ash ceramsite and the like. However, because the lightweight coarse aggregate has large internal porosity and weak material compressive capacity, for lightweight aggregate concrete, the traditional lightweight coarse aggregate is the weak defect of lightweight aggregate concrete and is the origin of crack development in the compressive process; in addition, due to the pores in the lightweight coarse aggregate, the aggregate absorbs the moisture of cement paste in the stirring and forming process, so that the defect of poor flowability of fresh concrete is caused, and a thicker water film is easily formed around the lightweight aggregate, so that a weak interface transition area is formed. For the above reasons, the strength of the conventional lightweight aggregate concrete is generally low, and the strength is sharply reduced particularly under the condition of low density. Therefore, the research and development of novel lightweight high-strength lightweight aggregate concrete, particularly the lightweight aggregate concrete with high strength under the condition of low density, has important significance.
Disclosure of Invention
The invention mainly aims at the problem that the strength of lightweight aggregates such as ceramsite is low due to more pores, and develops a novel lightweight high-strength lightweight aggregate concrete.
The invention adopts the following technical scheme that:
a light high-strength lightweight aggregate concrete comprises the following substances in percentage by mass: 15.1-36.6% of cement, 7.2-14.8% of fly ash, 3.5-9.1% of silica fume, 25.1-47.9% of sand, 10.5-22.3% of water, 5.2-19.5% of foamed aluminum lightweight aggregate and 0.2-0.5% of efficient water reducing agent.
The foamed aluminum lightweight aggregate is made of foamed aluminum materials, and is cut into small cylinders with the diameter of 8-20 mm and the height of 8-20 mm by utilizing a linear cutting technology. The foamed aluminum is closed-cell foamed aluminum, each air hole in the foamed aluminum is mutually independent and closed, the aperture is 1.5-3.0 mm, the porosity is 80-95%, and the bulk density is 320-658 kg/m3And the compressive strength is 8.2-20.5 MPa. The foamed aluminum is required to be closed-pore foamed aluminum, so that cement paste can be effectively prevented from entering the inside of the aggregate, and the density is improved, and the sound insulation and heat insulation effects are reduced; compared with common artificial aggregates such as ceramsite and the like, the foamed aluminum selected by the invention has high compressive strength, and can obviously improve the compressive strength of the lightweight aggregate concrete under the condition of the same concrete density; in addition, the traditional artificial aggregate belongs to a brittle material, sudden damage is shown under pressure, the foamed aluminum is a metal material with very strong deformation capacity, and after the foamed aluminum is combined with a cement-based material, the lightweight aggregate concrete shows excellent ductility and toughness and has an excellent energy absorption effect.
The foamed aluminum lightweight aggregate needs to be subjected to surface treatment according to the following steps so as to improve the alkali resistance of the foamed aluminum:
(1) soaking the foamed aluminum aggregate in a 5% sodium hydroxide solution for 5 minutes, then cleaning the foamed aluminum aggregate with deionized water until the surface is clean, placing the foamed aluminum aggregate in a drying oven at 60 ℃ for 60 minutes, and drying the surface moisture;
(2) compounding 20% by mass of myristic acid with 80% by mass of ethanol solution, uniformly stirring to prepare surface treatment solution, soaking the foamed aluminum in the surface treatment solution for 5 minutes, taking out, draining, placing in an oven at 80 ℃ for 60 minutes, and curing the surface treatment solution on the surface of foamed aluminum aggregate;
the pouring method adopting the cement-based composite material comprises the following steps:
(1) weighing cement, fly ash, silica fume and sand, and mixing to form a uniform dry material mixture;
(2) then weighing the water reducing agent and water, and uniformly mixing to form an aqueous solution;
(3) adding the aqueous solution into the dry material mixture, and uniformly stirring to obtain cement mortar;
(4) adding the foamed aluminum lightweight aggregate subjected to surface treatment, and stirring uniformly to obtain the lightweight high-strength sound-insulation lightweight aggregate concrete.
Compared with the prior art, the invention has the following advantages: the density of the building member cast by the light high-strength lightweight aggregate concrete provided by the invention is 750-1870 kg/m3The compressive strength is 18.3-76.8 MPa. Compared with the common ceramsite lightweight aggregate concrete, the concrete has the characteristics of remarkably improved compressive strength when the density is similar, light weight, high strength and sound insulation, and is very suitable for civil engineering buildings with super-large span bridges, large span spaces and high sound insulation requirements.
