Abstract
The invention provides a lightweight concrete. The lightweight concrete comprises, by mass, 150 to 180 parts of water, 50 to 80 parts of cement, 300 to 350 parts of cobblestone, 120 to 180 parts of river sand, 0.3 to 0.5 part of a foaming agent, and 3 to 5 parts of an additive. The energy-saving environmental-friendly lightweight concrete is prepared via mixing cement with cobblestone, the conventional materials, and the additive.
Description
Technical field
The present invention relates to concrete field, particularly relate to a kind of light weight concrete.
Background technology
Light weight concrete is that a kind of profit is useless, environmental protection, energy-conservation, cheap and there is non-flame properties novel building energy-saving material.Light weight concrete (foamed concrete) needs the gases such as air or nitrogen, carbon dioxide gas, oxygen to introduce in concrete mortar according to application by the mode of chemistry or physics, shaping through reasonable maintenance, and formed containing tiny in a large number sealed porosity, and there is the concrete product of suitable intensity.The foaming agent aqueous solution is normally mechanically prepared into foam by the making of light weight concrete (foamed concrete).
Summary of the invention
Provide hereinafter about brief overview of the present invention, to provide about the basic comprehension in some of the present invention.Should be appreciated that this general introduction is not summarize about exhaustive of the present invention.It is not that intention determines key of the present invention or integral part, and nor is it intended to limit the scope of the present invention.Its object is only provide some concept in simplified form, in this, as the preorder in greater detail discussed after a while.
The object of this invention is to provide a kind of light weight concrete, object is to adopt common material to form the concrete material of energy-conserving and environment-protective.
The invention provides a kind of light weight concrete, it is characterized in that, comprise the material of following massfraction: water: 150-180, cement: 50-80, pebbles: 300-350, river sand: 120-180, whipping agent: 0.3-0.5, admixture: 3-5.
Concrete provided by the invention, by adopting pebbles and conventional material, forms the light weight concrete of energy-conserving and environment-protective by admixture.
Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, be clearly and completely described below to the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not paying creative work, all belongs to the scope of protection of the invention.
