Description
Technical field
The present invention relates to a kind of concrete, being specifically related to is a kind of LC concrete (light aggregate concrete).
Background technology
Concrete, referred to as " concrete (t ó ng) ": refer to the general designation that is cemented to overall engineered composite material by gelling material by gathering materials.Conventionally concrete one word of saying refers to cement makes gelling material, and sand, masonry gather materials; Coordinate by a certain percentage with water (adding or do not add admixture and adulterant), through stirring, moulding, maintenance and cement concrete, also claim normal concrete, it is widely used in civil construction project.
Normal concrete is the concrete that we commonly use under construction, and apparent density is 1950～2750Kg/ cubic meter, mainly formulated for mainly gathering materials with sand, stone.And light aggregate concrete, its apparent density is at 800～1950 ㎏/cubic meters, and gathering materials of LC concrete (light aggregate concrete) comprises: industrial waste slag, haydite, pearlstone, expanded slag powder, slag powders etc.As can be seen here normal concrete density too large, can not recycle waste construction material, overall performance is all not as light aggregate concrete, wasted greatly national resources, can not be energy-conservation, not environmental protection again.
Existing light aggregate concrete exists production cost high, and existence can not be in a large number the defect such as recycles to dump slag powder, industrial grain slag etc.

Described light-weight aggregate tap density grade Application Range is: 1200～1900 ㎏/cubic meters; Strength grade Application Range is: LC30～LC45; Thermal conductivity Application Range is: 0.57～0.76W/M.K;
Further, described cement is general cement, mainly: six large class cement, i.e. silicate cement, ordinary Portland cement, slag powders silicate cement, Portland pozzolana cement, Portland fly ash cement and composite Portland cements of GB175-2007 regulation;
Further, described Additive proportioning is: flyash 1%～10%; Surplus is slag powders, can part place of cement, and the ratio of place of cement can reach 40%;
Screening formulation one: cement 20%, building solid waste 9%, cinder 16%, slag 12%, industrial roach sintered particles 7%, industrial grain slag 14%, flyash 4%, slag powders 10%, water 8%;
Screening formulation two: cement 28%, building solid waste 9%, cinder 5%, slag 12%, industrial roach sintered particles 10%, industrial grain slag 14%, flyash 4%, slag powders 10%, water 8%;
Screening formulation three: cement 15%, building solid waste 5%, cinder 15%, slag 12%, industrial roach sintered particles 17%, industrial grain slag 14%, flyash 4%, slag powders 10%, water 8%.
The relative prior art of the present invention has following beneficial effect:
Cinder of the present invention, industrial grain slag and industrial roach sintered particles; the waste materials accounting examples such as building waste have reached more than 50%; can by a large amount of trade wastes, pollutent recycling and produce economic worth and social benefit, the object that can reach protection of the environment, economizes on resources.
Embodiment
