Description
Technical field
The present invention relates to a kind of with light heat-insulation mortar bed cross recycled concrete block and preparation method thereof, belongs to a kind of novel energy-conserving, sharp useless, complex heat-preservation concrete block.
Background technology
Along with the needs of development of social production and people's life, various forms of buildings are rised sheer from level ground.In these buildings, masonry is often used as load-bearing or space enclosing structure.For this reason, the consumption of masonry is also in sharp increase.The masonry type that loam brick uses in a very long time as China once was applied as in the load-bearing or enclosed structure in the building widely.A large amount of uses of clay solid brick have caused the irrecoverable property destruction of farmland and land resources, and this runs counter to China's STRATEGIES OF SUSTAINABLE DEVELOPMENT.In order to implement the fundamental state policy in China protection soil, country forbids strictly the use of clay solid brick and adopts other new wall material.
Concrete hollow block is exactly the optimal selection of loam brick as an alternative, and it has easy, the advantages such as making is simple, easy construction of drawing materials; And also have huge social benefit and environmental benefit at joint soil, sharp aspect such as useless.Therefore, the development concrete hollow block is an inexorable trend.But, on the one hand, along with the increase of concrete hollow block consumption, the more concrete of inevitable demand, correspondingly be that a large amount of natural sandstone aggregates are constantly exploited, it is exhausted that the natural aggregate resource also is tending towards; Along with the arrival of China's building cycle, the quantity of building waste has accounted for 30%～40% of municipal refuse total amount on the other hand, and wherein most important component is a discarded concrete; Available coagulation soil building-block masonry exists problems such as globality is poor, cracking resistance is poor, thermal insulation is poor, impermeability is poor on the one hand again; Existing common yi word pattern concrete block simultaneously a little less than the connection each other, especially in the junction of wall in length and breadth, also proves in all previous earthquake, in length and breadth the wall junction weak spot of earthquake especially.These have influenced concrete block applying in China to a certain extent.
Summary of the invention
The object of the invention is to provide a kind of cross recycled concrete block of energy-conservation complex heat-preservation of being used for interior exterior wall crossover sites that collection is in light weight, premium properties such as intensity is high, overall performance good, energy-saving heat preserving, sound insulation is good, anti-seismic performance is good, easy construction are one that is mainly used in exterior-wall heat insulation, to solve problems such as the order globality is poor, cracking resistance is poor, thermal insulation is poor, impermeability is poor.
